What is fabrication vs welding?

Fabrication and welding are two processes that are used to join metal components together to create structures or machines. Both processes involve the use of heat and pressure to bond metal components, but there are some key differences between the two.

Fabrication is the process of cutting, shaping, and assembling metal components to create a structure or machine. This process can involve a variety of techniques, such as bending, rolling, punching, and sawing, to form the metal into the desired shape. Fabrication can be done using a variety of tools, including hand tools, power tools, and machines.

Welding, on the other hand, is a process that involves melting and fusing metal components together to create a strong, permanent bond. Welding can be done using a variety of methods, including gas metal arc welding (GMAW), shielded metal arc welding (SMAW), flux-cored arc welding (FCAW), and tungsten inert gas welding (TIG). Each method uses a different type of welding process and equipment to create the weld.

One key difference between fabrication and welding is the type of metal that can be used. Fabrication can be used with a variety of metal types, including steel, aluminum, brass, and copper, while welding is typically limited to ferrous metals, such as steel and iron.

Another difference is the type of joints that can be created. Fabrication can create a variety of joints, including butt joints, lap joints, and T-joints, while welding is typically limited to creating butt joints.

In terms of the strength of the joint, welding is generally considered to be stronger than fabrication. This is because the welded joint is created by melting and fusing the metal together, creating a bond that is stronger than the metal itself. Fabrication, on the other hand, relies on the mechanical strength of the joint, which may not be as strong as a welded joint.

One advantage of fabrication over welding is the speed at which the process can be completed. Fabrication can often be done more quickly than welding, especially if automated equipment is used.

In terms of cost, fabrication is generally considered to be less expensive than welding, especially for large projects. This is because fabrication does not require specialized equipment or training, and it can be done using a variety of tools and machines. Welding, on the other hand, requires specialized equipment and training, which can increase the cost of the process.

Overall, fabrication and welding are both important processes that are used to create strong, durable structures and machines. While they have some similarities, they also have some key differences, including the type of metal that can be used, the type of joints that can be created, and the strength of the final product.
