Types of welding 1.Plastic Welding • In Plastic welding or pressure welding, the pieces of metal to be joined are heated to plastic state and then forced together by external pressure. 2. Fusion Welding • In fusion welding or non pressure welding , the material at the joint is heated to molten state and allowed to solidify. Welding Processes 1.
Arc Welding Circuit. The electric arc winding circuit can be formed by an electric arc among the electrode as well as the workpiece. The temperature of the arc may arrive at 5500°C (10000°F), which is enough to combine the edges of the workpiece. Once a long join is necessary then the arc can be moved through the joint line.
