There are two types of welding methods.
- Leftward welding (forehand welding).
- Rightward welding (backhand welding).
The welding rod is held in left hand and blowpipe is held in right hand. Leftward welding is used for the metal plate thickness up to 3 mm. Welding proceeds from right to left. It is also known as forward or forehand welding. The inclination of welding rod with plate is 30°–40° and inclination of blowpipe with plate is 60°–70°.
Right-ward welding is used for thicker plates and proceeds from left to right. The inclination of welding rod is same as in the leftward welding but inclination of blowpipe is 10°–20° less than that in the leftward welding, i.e., at 40°–50°. It is also known as backward or backhand welding.
