The welding processes

Welding Welding is a process of joining similar metals by application of heat, with or without application of pressure, with or without adding the filler material, with or without using flux. The welding processes generally used are classified into two main groups: (a) Pressure Welding (b) Fusion Welding or Welding without Pressure In pressure welding, the surfaces to be joined are heated to a plastic state. Then forced together by external pressure to make the joint. This process is used in Forge Welding, Resistance Welding and Pressure Thermit Welding. Fusion…
