Does arc welding utilize an electrical current to melt metal and fuse parts together?

Explanation:
Arc welding relies on an electric arc that generates intense heat between an electrode and the workpiece. This heat melts the metal at the joint, creating a molten pool that fuses the parts as it solidifies. The electrical current, which can be AC or DC, is the energy source driving that arc. Shielding gas or flux protects the molten metal from contamination, ensuring a strong weld. Because the heating and joining come from the electric arc, this process uses electrical current to melt metal and fuse parts together.
