Pipe-to-pipe joint arc welding in galvanized iron (GI) involves specific considerations to ensure safety and a strong, durable weld.
Set Up the Welding Machine: Adjust the welding machine to the appropriate settings based on the electrode type and the thickness of the GI pipes.
Tack Welds: Start with tack welds to hold the pipes in place. Place tack welds at evenly spaced intervals around the joint.
Weld the Joint:
Begin welding at one end of the joint, maintaining a consistent speed and angle.
Use a weaving motion to ensure good penetration and coverage.
Avoid excessive heat, as it can cause burn-through or weaken the joint.
