How Metal Fabrication Is Used In The Agricultural Industry

Metal fabrication is a crucial aspect of modern agriculture that enables farmers to increase efficiency and productivity. From customizing machinery to improving the durability of tools, metal fabrication has numerous benefits for the agricultural industry. In this post, we’ll explore the different processes involved in metal fabrication and how they can positively impact the agricultural industry.

Understanding Metal Fabrication in the Agricultural Industry

Metal Fabrication

What is Metal Fabrication and what processes are considered fabrication?

Metal fabrication refers to the process of transforming raw materials into finished products through
a variety of processes such as cutting, bending, and assembling a product e.g. typically by welding individual components together. Other processes that sometimes are included under metal fabrication are stamping, punching and even CNC machining as well as various surface treatments, i.e. hot dip galvanising, powder coating and wet spray painting. The end-result is a finished product that is both functional and durable, which is essential for the demanding environment of the agricultural industry.

Cutting: There are several methods for cutting large steel plates in the manufacturing industry, including:

  1. Oxy-Fuel Cutting: This is a traditional method that uses a flame and a mixture of oxygen and fuel gases, such as acetylene or propane, to heat the steel plate to its ignition point and then burn through it.
  2. Plasma Cutting: This is a high-precision cutting method that uses a plasma torch to create a high-temperature plasma arc that cuts through the steel plate.
  3. Laser Cutting: This is a highly precise method that uses a laser beam to cut through the steel plate. It is commonly used for intricate cuts and is ideal for cutting thin or delicate materials.
  4. Waterjet Cutting: This is a process that uses high-pressure water to cut through the steel plate. The water is mixed with abrasive particles, such as garnet, to increase its cutting power.
  5. Saw Cutting: This method uses a saw, such as a band saw or circular saw, to cut the steel plate. It is typically used for rough cuts and is not as precise as other cutting methods.
  6. Shearing: This method uses a shearing machine to cut the steel plate by applying pressure to two opposing sides. It is commonly used for straight cuts and is suitable for cutting both thin and thick plates.

Each of these cutting methods has its own advantages and disadvantages, and the most suitable method will depend on factors such as the thickness of the plate, the type of steel, the desired accuracy of the cut, and the size of the plate.

.

Bending: Bending is often used in the manufacturing industry to shape metal or other materials into specific shapes. There are several methods for bending metal, including:

  1. Roll Bending: This is a process in which a metal plate is passed through three rolls that gradually bend the metal into the desired shape. It is commonly used for large, heavy plates and is capable of producing tight radius bends.
  2. Press Brake Bending: This is a process in which a metal plate is placed between a punch and die and then subjected to force from a hydraulic press. The punch and die shape the metal into the desired bend.
  3. Folder Bending: This is a process that uses a folder machine to bend metal into complex shapes, such as those found in metal forming and welding.
  4. Tube Bending: This is a process in which a metal tube is bent into the desired shape, usually using a tube bender.
  5. Hydraulic Pipe Bending: This is a process in which a metal pipe is bent into the desired shape using a hydraulic press.
  6. Mandrel Bending: This is a process in which a metal tube is bent around a mandrel to maintain the shape of the interior of the tube during the bending process.

The choice of bending method will depend on factors such as the thickness and type of metal, the desired radius of the bend, and the complexity of the bend shape.

Welding: Welding is a metal fabrication process that joins two pieces of metal by heating the surface to the melting point and fusing the metals together. This is accomplished through the use of heat sources such as electric arc or gas flame, and filler materials are sometimes added to enhance the bond. The final result is a solid, homogeneous joint between the two pieces of metal. There are several types of welding, including:

  1. Shielded Metal Arc Welding (SMAW): This is also known as stick welding and is one of the oldest and most versatile welding methods. An electrode is coated in flux and used to create an arc between the electrode and the metal being welded. The heat from the arc melts the metal, and the flux creates a shield to protect the weld from contamination.
  2. Gas Tungsten Arc Welding (GTAW): This is also known as Tungsten Inert Gas (TIG) welding and is a precision welding method that uses a tungsten electrode to create an arc. A shielding gas, such as argon, is used to protect the weld from contamination.
  3. Gas Metal Arc Welding (GMAW): This is also known as Metal Inert Gas (MIG) welding, and is a semi-automatic or automatic welding method that uses a continuous wire feed and a shielding gas to protect the weld from contamination.
  4. Flux Cored Arc Welding (FCAW): This is a variation of MIG welding that uses a flux-cored wire instead of a solid wire. The flux in the core of the wire provides shielding, eliminating the need for a separate shielding gas.
  5. Submerged Arc Welding (SAW): This is a highly automated welding method that uses a consumable electrode and a granular flux to produce a deep, high-quality weld.
  6. Resistance Welding: This is a welding method that uses electrical resistance to generate heat and melt the metal being welded. The metal is then brought into contact, and the pressure from the electrodes creates the weld.

Although a lot of welding is still performed manually, the implementation of robotic welding is increasingly popular. Robotic welding is a type of welding in which a robot is used to perform the welding process, typically using the Gas Metal Arc and Flux Cored Arc Welding discussed above.

The robots are programmed to perform specific welding tasks and can be reprogrammed for different tasks as needed.

Advantages of robotic welding over traditional welding include:

  1. Increased Efficiency: Robotic welding can operate faster and more consistently than manual welding, leading to increased productivity and lower costs.
  2. Improved Quality: Robotic welding provides consistent and precise welds, reducing the risk of errors and rework.
  3. Increased Safety: Robotic welding reduces the risk of injury to human operators, as the robot performs the hazardous and repetitive aspects of the welding process.
  4. Repeatability: Robotic welding provides consistent results every time, making it ideal for mass production and high-volume manufacturing.
  5. Flexibility: Robotic welding systems can be programmed and reprogrammed to perform different welding tasks, making them suitable for a wide range of applications and industries.
  6. 24/7 Operation: Robotic welding systems can operate continuously, eliminating the need for breaks and increasing the overall output.

However, it should be noted that while robotic welding offers many advantages, it also requires a significant investment in equipment, training, and maintenance. In addition, the initial setup and programming of a robotic welding system can be complex and time-consuming.

Finishing: There are many finishing processes, in metal fabrication, and each has its own purpose and function. Some examples of common surface treatment include:

  1. Anodising: This is a process used to increase the thickness of the natural oxide layer on the surface of aluminium and its alloys, improving its resistance to corrosion and wear.
  2. Electroplating: This is a process in which a metal is deposited onto the surface of a workpiece by means of electrochemical deposition. It is used to add a protective layer, improve conductivity, or to change the appearance of the material.
  3. Painting: This is a process in which a paint or coating material is applied to the surface of a material to provide protection or enhance its appearance.
  4. Powder Coating: This is a process in which a dry powder material is electrostatically applied to a surface and then cured under heat to form a protective and decorative coating.
  5. Sandblasting: This is a process in which abrasive particles are propelled at high speed onto the surface of a material to clean, texture, or prepare it for further processing.
  6. Shot Blasting: This is a process in which abrasive particles are projected at high velocity onto the surface of a material to clean, surface finish, or prepare it for further processing.
  7. Polishing: This is a process in which a material is mechanically abraded to produce a smooth, reflective surface finish.
  8. Passivation: This is a process in which the surface of stainless steel or other metal alloys is treated to remove impurities and improve its resistance to corrosion.
  9. Heat Treatment: This is a process in which a material is subjected to high temperatures to alter its properties, such as its strength, hardness, or ductility.

The choice of surface treatment will depend on factors such as the material, the desired properties and appearance, and the end-use of the product.

New Innovations in Agricultural Mechanization: Improving Efficiency and Productivity

Agricultural-Machinery

The agricultural industry is always looking for ways to improve efficiency and productivity. Over the years, new innovations have been developed to help farmers meet these goals. From precision agriculture to autonomous tractors, there have been significant advances in the field of agricultural mechanization. Here are a few examples of new innovations that are revolutionizing the way we farm:

  • Precision Agriculture: Precision agriculture is a rapidly growing field that involves using technology to improve the efficiency and productivity of farming. This includes the use of GPS, drones, and sensors to gather data about the health of crops and soil, as well as to automate tasks such as planting and harvesting. Precision agriculture has the potential to revolutionize the way we farm, allowing farmers to make more informed decisions and maximize yields.
  • Autonomous Tractors: Autonomous tractors are another new innovation in the field of agricultural mechanization. These tractors are equipped with advanced navigation and sensing systems that allow them to operate without human intervention. This technology has the potential to increase efficiency and reduce labour costs, making it an attractive option for farmers looking to improve their bottom line.

As increasingly more manufacturing companies become environmentally conscious and farmers become more demanding of high efficiency machines, new technologies are starting to gain popularity, not just in agricultural machinery manufacturing, but across all manufacturing industries. Some of these new technologies are:

  1. Additive Manufacturing (3D Printing): This is a process in which three-dimensional objects are built up layer by layer from a digital model, allowing for the creation of complex shapes and structures. This process is being used in the production of small and lightweight parts for tractors and other agricultural machinery.
  2. Robotic Welding: This is a process in which a robot is used to perform welding tasks, improving efficiency and reducing the risk of human error. This process is commonly used in the production of large, complex agricultural machinery components.
  3. Hydroforming: This is a process in which a metal tube is placed inside a die and then subjected to high pressure to form it into a complex shape. This process is being used in the production of high-strength and lightweight structural components for tractors and other agricultural machinery.
  4. Composite Material Processing: This is a process in which composite materials, such as fibre-reinforced plastics, are moulded and shaped into complex components. This process is being used in the production of lightweight, corrosion-resistant components for tractors and other agricultural machinery.

When to Stick with Simple Traditional Fabrication

While new innovations have the potential to bring many benefits to the agricultural industry, it is important to remember that sometimes, simple traditional fabrication methods are still the best option. For example, traditional fabrication methods may be preferred in certain situations where:

  • Reliability is a top concern: Simple, traditional fabrication methods have been tried and tested over many years, and they are known for their reliability.
  • Complexity is not necessary: In some cases, simple machinery may be all that is needed to get the job done. When weight is not a critical factor, there is no real need to consider 3D printing or composite materials as these are a lot more expensive and require an adequate amount of expertise, which most manufacturers would have to invest in.
  • Cost is a factor: new innovations often come with a higher price tag. Farmers may not be able to justify the much higher price point unless the expected achievable performance is seen as an opportunity to gain great returns.

Common Applications of Metal Fabrication in Agriculture

agricultural-machinery

There are several common applications of metal fabrication in the agriculture industry, including:

  1. Tractors: Tractors are widely used in Australian farming for a variety of tasks, such as ploughing, cultivations, planting, and harvesting. They are also used to power a variety of implements, such as tillage equipment, cultivators, and mowers.
  2. Combine Harvesters: Combine harvesters are used for the simultaneous harvesting of crops such as wheat, barley, and canola. They cut and thresh the grain, separating the grain from the straw.
  3. Sprayers: Sprayers are used to apply fertilizers, herbicides, and pesticides to crops. There are both ground-based and aerial sprayers available, depending on the type of crops and the size of the farm.
  4. Hay Balers: Hay balers are used to make bales of hay and silage, which are then stored for use as animal feed. Round balers and square balers are the two most common types of hay balers used in Australia.
  5. Irrigation Equipment: Irrigation equipment, such as centre pivot irrigation systems and drip irrigation systems, are used to supply water to crops in areas where rainfall is insufficient.
  6. Ploughs: these are used to turn over the soil and prepare the ground for planting. They can be either mounted on tractors or pulled behind them.
  7. Mowers: Mowers are used to cut grass for hay or silage production. They can be either trailed behind tractors or mounted on them.

Every cultivation requires different machinery. In cotton cultivation, for example, farmers require a wide range of machinery, for example:

  • Cotton Pickers: Cotton pickers are specialized harvesting machines used to harvest cotton bolls from the plant. They have multiple spindles that spin and grab the cotton bolls, which are then stripped from the plant and deposited into a basket for collection.
  • Cotton Strippers: Cotton strippers are used to strip the leaves and branches from the cotton plant prior to harvest. This helps to reduce the amount of green material in the harvested cotton and can improve the quality of the fibre.
  • Bed Formers: Bed formers are used to create raised beds for planting cotton. The beds can be either flat or raised, and they help to improve drainage and reduce soil erosion.
  • Row Crop Cultivators: Row crop cultivators are used to control weeds and prepare the soil for planting. They have adjustable shanks that can be set to the correct depth for different crops, and they can be used to cultivate between the rows of cotton plants.
  • Irrigation Equipment: Irrigation equipment, such as centre pivot irrigation systems and drip irrigation systems, is used to supply water to cotton crops in areas where rainfall is insufficient.

Compared to the agricultural machinery used for cultivating grain crops, the machinery used for cultivating cotton is generally more specialized and designed specifically for cotton production. Cotton pickers and strippers, for example, are not used for grain crops, and the shanks on row crop cultivators are often set at a different depth for cotton than for grain crops. Additionally, cotton crops are often irrigated, which is not as common for grain crops, so cotton production requires specialized irrigation equipment.

Macadamia Nut harvesting requires dedicated machinery as well. Some of these are:

  • Harvesters: Macadamia nut harvesters are specialized machines used to harvest macadamia nuts from the trees. They typically have a shaking mechanism that is used to shake the nuts from the tree, and they are designed to minimize damage to the nuts and trees during the harvest process.
  • Nut Graders: Nut graders are used to sort and grade the harvested macadamia nuts based on size, shape, and quality. This helps to ensure that the nuts are processed and marketed according to their value.
  • Nut Shellers: Nut shellers are used to crack open the tough macadamia nut shells and extract the kernels inside. They can be either manual or automatic, and they are designed to be efficient and produce high-quality kernels.
  • Orchard Maintenance Equipment: Orchard maintenance equipment, such as tractors and mowers, is used to maintain the health and productivity of the macadamia nut trees. Tractors can be used to plough the orchard, and mowers can be used to cut grass and weeds.
  • Irrigation Equipment: Irrigation equipment, such as drip irrigation systems, is used to supply water to the macadamia nut trees in areas where rainfall is insufficient. This helps to ensure consistent and optimal growth of the trees and high-quality nut production.

Compared to the machinery used for cultivating other crops, the machinery used for macadamia nut cultivation is often smaller and more specialized. Macadamia nut harvesters, for example, are typically smaller than grain harvesters, and macadamia nut shellers are designed to handle the specific challenges of cracking macadamia nut shells. Additionally, macadamia nut cultivation often requires precise irrigation, which is why specialized irrigation equipment is often used.
