schematic diagrams of different welding processes

1. WELDINGWELDING

2. Welding is a process for joining two similar or
dissimilar metals by fusion. It joins different
metals/alloys, with or without the application
of pressure and with or without the use of filler
metal. The fusion of metal takes place by means
of heat. The heat may be generated either
from combustion of gases, electric arc, electric
resistance or by chemical reaction.Welding
provides a permanent joint
