Welding is a huge facet of custom manufacturing, but it is not as simple as “To weld, or not to weld.”  While the allure of this trade usually balances on the ornate sparks and powerful equipment, there are several other complexities that are taken into account by your manufacturer.  Technique and processes are different depending on your specific project and the materials being used.  Each project requires a steady hand and professional understanding of what will be most efficient and cost effective. Two such techniques taken into consideration are MIG and TIG welding.

MIG Welding

Metal Inert Gas or MIG welding is the most widely used technique.   The welder will use a continuous feeding wire to burn, melt and fuse both the base and parent metals together quickly while also allowing a range of material thicknesses. MIG welding, another term for “gas metal arc welding, ”or GMAW can cover a lot of ground quickly with a variety of materials such as mild steel, stainless steel and aluminum.

TIG Welding

Tungsten Inert Gas or TIG welding is a more delicate process.  It is more commonly used for thinner gauge materials and allows the welder to use lower power and not blow through the metal.  TIG welding also allows the welder a more precise finish and will require little to no grinding or sanding for weld cleanup.
