WELDER(MIG ARC WELDING)
This welding process uses inexpensive carbon dioxide
instead of expensive inert gases as a shielding means.
Consumable metal electrodes are employed. It has a
wide range of applications, including butt welding of thin
plate, fillet welding, plug welding, and MIG spot weld-
ing. In terms of the weld strength, it is also highly stable.
