Need a welding jig

Working on a little project that requires welding a 3/8" Sch 40 pipe nipple to a piece of 1/4" angle iron. The angle iron has a hole bored to let the pipe pass through and then the pipe is to be welded at that point. The pipe must be perpendicular to the angle iron. I can start with the pipe straight but after the first tack weld the weld draws up and overcomes every clamping device I've come up with yet. Appreciate any thoughts.

Ray, maybe you need to make up an adjustable jig with the metal going up against set screws. Put one in, weld it and then adjust the set screws till you get the parts like you want them....lock the set screws with nuts and make the weld the same way everytime. I've made jigs that the part went in crooked but came out straight after weld warp. Also, have welded parts in fixture and after welding, had to straighten long slender members with a jack and chain with fabrication hanging from a forklift L8R....Fred OH

Hi Ray,

You can run a rod/bolt thru the pipe then tack that to the welding bench on both sides. If the rod/bolt is tight enough then the pipe will not move side/side or up/down. I would still tack as Bill instructed. Being as small as the parts are, if you don't tack the "jig" down to something solid, I think it will move out of square when you put on the cover pass.

With the magnetic holders I found the arc will be very difficult to control because of the magnetic field. The same reason why you don't want welding lead coiled.

I use those magnetic 90 degree magnets to hold it straight,you need two one 90 degrees from the other.

I'm no expert, but have played with similar set-ups before. I've found that with pipe, you tack one side (enough to hold but still bendable); when it cools, tap it over until it is straight and tack the other side of pipe, 180 degrees from the first tack weld. Then do one at 90 degrees, straighten, and the final one 180 degrees from that. When the last weld has cooled, de-slag and weld all the way around. I used this method to weld a steel rod to a backing plate to attach wheel weights to my compact tractor, they both came out very straight.
