I'm new to welding and playing around with a tig. Whenever I try to weld two pieces of steel (angle iron or square tubing) together at a right-angle, even using a right-angle vise, the shrinkage after cooling reduces the angle to something less than 90 deg. What tricks or techniques do people use to end up with a solid 90? Thanks.Involute
Reply:Lots of tacks, or I open the angle up a little so it pulls back to 90.David Real world weldin. When I grow up I want to be a tig weldor.
Reply:Like David saysAlso if it's a manageable piece. Tack it at 90 degrees, but on one side first. Take a hammer and adjust it back to 90 after it shrinks, then tack the other side.Tack one side....square/plumb.....tack other side"Any day above ground is a good day"http://www.farmersamm.com/
Reply:weld the top and the bottom first and then weld the inside and outside of the angle. comes out pretty close if you start with lots of tacks. put a square on it after the top and bottom are welded and if it has tightend up weld the outside first or vise versa
Reply:here is a video that has a good explaination. pretty funny too tanglediver posted a while back.fred
