Welding C Purlin. On repairs 6011 and 6010 332 will weld over paint and rust. The heat produced in welding will affect the material properties of the high yield strength cold-formed steel used in purlins.
Getting galvanized in terms of longevity and durability. I work as a Mig welder welding bumpers up all day. In many instances considerable stress concentrations are likely to arise even with good quality welding.
They are welding a lot of the c purlins to each other with a mig welder and seemingly no prep work.
C Purlin 6 X 2 X 14 GA-25FT In Stock For additional item location Click Here. Ive recently purchased a Hobart 250 generator welder and got a deal. I plan to use 316 4x4 tubing as the support posts with 20 ft 4x4 I beams welded to the top of the posts. My question is about what amp range would be the best to weld the c purlin.
