How Does Arc Welding Work?
Arc welding works by creating an electric arc between an electrode and the workpiece. This electric arc generates intense heat, which melts the metal surfaces and the electrode. The electrode, often made of a filler material, provides additional molten metal to join the parts together.
The process begins with the setup of the welding machine, which generates the electrical current. An electrode is then brought close to the workpiece without touching it. When the gap is small enough, the electrical current jumps across, forming an arc. The arc’s heat quickly melts both the base metals and the electrode.
As the operator moves the electrode along the joint, the molten metal pools together and solidifies, forming a strong bond as it cools. Shielding gas or protective coatings often surround the arc to shield the molten weld from contamination. This process allows for effective and efficient joining of metal parts in various applications.
