WELDING AND TOOLS 3–5
NOTE: Below is an example of how not to perform gas
welding, avoid operations like this.
3. CARBON DIOXIDE ARC
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.
• Welding the bending angle of a flange
• Melting the finger end of a flange
