Electric Arc Welding
The welding in which the electric arc is produced to give heat for the purpose of joining two surfaces is called Electric arc welding.
Gas Arc welding

Gas welding is the process in which a gas flame is used to raise the temperature of the metal to be joined. The metals are heated up to melting. The metal flows and on cooling it solidifies. A filler metal may be added to the flowing molten metal to fill up cavity made during the end preparation. Many combination of gases are used in Gas welding. But most common of these in oxygen and acetylene.
Welding Techniques
Forge welding:
This welding is done by the black-smiths. In this two similar metal pieces are heated upto the plastic stage in the furnace. Then it is hammered so that a homogenous mixture is formed at the joint. The surface to be joined should be cleaned and made free from any foreign particle this is done by brushing.

Welding is a process of joining two materials with the help of heat or pressure or by some other means. The cost of welding is very less as compared to other processes and forms a strong joint.
