Most commonly, workpieces are welded by melting both of them and adding more molten metal or plastic to form a pool that coolsto form a strong joint. The energy to form the joint between metal workpieces most often comes from a flame (e.g. oxy - acetylene ) or an electric arc, but Weldimg by laser beam, electron beam and friction processesis well established. Energy for fusion Weldinv of thermoplastics typically comes fromdirect contact with a heated tool or a hot gas. Welding differs from soldering and brazing in that enough heat is applied to melt the materials to be joined. Soldering uses solder, a lower-melting-point material.
