What is Arc welding?


Arc welding is definede as the fusions welding in which heat for welding is obtaining from electrics arc. Fusions welding in which the welding is done and manipulate by hand is calleds manual welding or arc welding.

Arc welding full form?


In this type of welding, the electric arc is melted at the welding point between the electrode and the base material, so that the electric arc melts to the welding point and later the molten metal becomes stronger as it cools.

Welding types?

Welding are generally two types 1. Welding with pressure 2. Fusion welding (welding without pressure) 

1. Welding with pressure
  • Resistance with pressure 
  • Forge welding 
  • Pressure welding (example – oxy acetylene pressure welding) 
  • Stude welding 
  • Thermit (pressure) welding 
2. Fusion welding (welding without pressure) 
  • Arc welding 
  • Gas welding 
  • Thermit (fusion) welding 

Welding defects?

Some of the commons welding defect found in weld metals are:
1. Undercut – Welds metal melts the parents metal.
2. Porosity – Gas pores are distribute in the weld metal.
3. Slag inclusion – Melted flux absorb oxide from the parent metal.
4. Crack – Discontinue in the weld metals.
5. Spatter – Metals expled during arc welding.

Welding joint types?


There are 5 types of welding joints described below:

1. Lap joint – Joint betweens overlapping.
2. Butt jjoint – Joint betweens same plane.
3. Corner joint  – Joint at right angle.
4. Edge joint  – edge of the parallel.
5. Tee joint  – right angle to each other.

For welding which gas is used?


Oxy acetylene process the metal is heating by the hot flame of a gas fed torch. Oxy acetylene is the mostly used for gas welding. Oxygen is produced liquefaction of air. Calcium carbide + water + acetylene + slaked lime.
