minimizing distotion
(OP)
We have to weld several 0.50 thk. CS weld joints that have double bevels and backing straps. These weld seams are 70 - 80 ft. in length. The contractor wants to use 3-4 welders per seam & divide up the weld length equally. They want to preset the weld seams about 10 mm and secure them with temporary bracing. I am looking for a weld sequence that would minimize the distortion. I have some ideas but my experience in this type of welding is limited. The welding code is AWS D1.1 & they will be using GMAW or SMAW.
