What Are the Sheet Metal Fabrication Techniques?
Description of processes used for laser cutting
Laser cutting is an effective process used to cut or engrave materials in sheet metal fabrication. This method involves pointing a high-powered light beam directly on the sheet metal surface and then heating it up until it melts or vaporizes, thereby forming the desired shape. Laser cutting perfectly deals with complex designs that have clean edges and minimum waste. The reason behind this technique being commonly used when cutting stainless steel, aluminium and mild steel is because of its accuracy and quickness. These procedures enable enhanced customization and repetition thus are vital in industries like automotive, aerospace, manufacturing etc.
Welding and joining help to fabricate sheet metals, putting together metallic parts in such a way that they become useful. The welding process consists of using high temperature, pressure or both to melt together two or more pieces of metal, usually with the aid of an additional material. Examples include Metal Inert Gas (MIG), Tungsten Inert Gas (TIG) and Spot Welding.
For thicker sections MIG Welding is used extensively because it is fast; material deposition rates can be as high as 8-10 pounds per hour.
Again, Thin materials are suited for TIG Welding which enable welding that has minimal distortion.
Within automated systems Spot-Welding joins overlapping sheets of metal at a rate of between 500 and 1000 welds per minute respectively.
