The Demand of Welders in Metal Fabrication Industry

1 Dec , 2015  

The working of a metal fabrication industry involves bending, cutting and reassembling of metals to create new products and beautiful designs. It also involves designing and manufacturing machines using various raw materials. Their work involves many processes for creating the finished product. These include cutting, welding, forming and designing. Welding is an integral part of this process, which is why good welding equipment and tools are in high demand in this industry.

The two main processes in which the welding machine comes in handy are cutting and reassembling of metal parts. Though cutting the metals can also be done using saws, shears and chisels, modern multi-purpose welders are equally effective in carrying out this process efficiently.

As far as reassembling of the metals is concerned, this is done using a welder. The final design of the blueprint can only be achieved with meticulous welding. Many different types of welders are used for this task in fabrication units. The welder used depends on the type of welding method being used. The three common types of welders are:

  1. Arc Welder: Also known as Shielded Metal Arc Welding (SMAW) or Manual Metal Arc Welding (MMA or MMAW) or even Stick Welding, this is one of the most common types of welding methods in the world. Stick refers to the electrode covered with a flux. To describe the process simply, as current flows through the electrode, it slowly melts and in the process, causes the metals in contact to melt and integrate creating a weld.
  2. TIG Welder: Also known as Gas Tungsten Arc Welding (GTAW), Tungsten Inert Gas (TIG) welding uses tungsten as the electrode. In this process, the electrode does not melt during the process but works towards protecting the welded area from any further contamination from atmospheric sources. It is done using an inert gas like argon.
  3. MIG Welder: Metal Inert Gas (MIG) welding is known as Gas Metal Arc Welder (GMAW) uses an electrode that melts during the process of melting. It protects the welded metal from atmospheric contamination by shielding it using an inert gas like a mixture of argon and helium.

Other than these there are other welding methods like Flux-Cored Arc Welding (FCAW) and Submerged Arc Welding (SAW) that are widely used in industrial fabrication units. The welders used for such processes are not suitable for home or workshop use. Multipurpose welders that integrate MMA, TIG, and MIG welders described above have also gained popularity in the metal fabrication industry.
