Do not overweld. … Use intermittent welding. … Use as few weld passes as possible. … Place welds near the neutral axis. … Balance welds around the neutral axis. … Use backstep welding. … Anticipate the shrinkage forces. … Plan the welding sequence.

What are the ways of controlling distortion?

• using tack welds to set up and maintain the joint gap.
• identical components welded back to back so welding can be balanced about the neutral axis.
• attachment of longitudinal stiffeners to prevent longitudinal bowing in butt welds of thin plate structures.

How do you prevent warpage and distortion?

Weld the assembly from inside to outside to avoid high shrinking stresses. Avoid the need to force, spring, or restrain components during welding. Avoid over-welding and use as few weld passes as possible. Continuously weld thick sections; however, thin sections may benefit from staggered welding.
