I made a jig to hold mine whilst being welded but the welder didn't think it was necessary and took it out of the jig to weld it. Also didn't use the bottle of purge gas I supplied so got it full of sugaring too but that's another issueAnyone?
Not all of them.Are the welding induced stresses not due to heat from the welding process ?
Just worl slowly and keep cooling the workpiece.
