Metal Fabrication is one of the traditional ways of creating heavy equipment and today many welding companies are providing a modern touch to this technique. Metal fabrication may be described as a value addition process that entails the construction of machines and structures from various raw materials.There can be no doubt that metal fabrication welding imparts strength and stability for a working equipment or device. Metal Fabrication and welding for heavy industrial devices lends itself to different work patterns and outputs.Fabrication is rather a wide term to denote building metal structures through the three different steps -cutting, bending, and assembling. The cutting part of fabrication is done by sawing\/shearing\/chiseling (either manual or powered); cutting is done via CNC cutters using laser, torch, or water jet). The bending is by means of hammering (manual or powered) or press brakes. The assembling is achieved mostly by welding - if not, through adhesives, riveting, threaded fasteners etc.Structural steel and sheet metal are the standard materials for fabrication - not to speak of the plastic pipe cutter wire, flux, and fasteners that will join the cut pieces. There are fabrication shops that undertake these jobs. The products produced by welders, which are often referred to as weldments are classic examples of fabrication. The field of welding continues to evolve with significant advancements in technology. There are highly skilled infrastructure fabrication welding operators who are adepts in basic welding and fabrication methods, blueprint reading etc.Several welding processes are used in metal fabrication. The two most common welding processes we know for fabricating metals are TIG (Tungsten Inert Gas) welding and MIG (Metal Inert Gas) welding. The other name for TIG is GTAW (Gas Tungsten Arc Welding) and MIG also is oftentimes referred to as GMAW (Gas Metal Arc Welding).
