What welding processes use constant current arc welding machines?

A. MIG Welding
B. TIG Welding
C. Stick Welding
D. Flux-Cored Arc Welding

Answer :

Final answer:

TIG Welding and Stick Welding are the two primary welding processes that utilize constant current arc welding machines, employing precise current control for quality joins. MIG and Flux-Cored Welding, on the other hand, generally use constant voltage systems. Hence the correct answer would be option b and c.

Explanation:

Welding is a sculptural fabrication process that joins metal materials using solder and heat. Among the various welding processes, certain ones specifically utilize constant current arc welding machines. These include:

  • TIG Welding
  • Stick Welding

TIG (Tungsten Inert Gas) Welding and Stick (Shielded Metal Arc Welding) operations are well-suited to constant current arc welding machines due to their need for precise current control, which is essential for the creation of strong, reliable joins in a wide range of metal types and thicknesses.

In contrast, processes like MIG (Metal Inert Gas) Welding and Flux-Cored Arc Welding generally utilize constant voltage systems designed to maintain a steady voltage level during welding, which is better suited to their specific operational requirements.
