Types of Electric Welding
1. Arc Welding: Uses an electric arc between an electrode and the workpiece to generate heat. Subtypes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and gas tungsten arc welding (GTAW).
2. Resistance Welding: Joins materials by passing current through the materials' contact points. Subtypes include spot welding, seam welding, and projection welding.
3. Induction Welding: This uses electromagnetic induction to heat the materials to be welded. This method is commonly used for continuous welding of pipes and tubes.
