29 gru 2007 · An advantage of bolting the clamps together is you could have several base plates made for different angles, not just 90 degrees. Typical ones might 22.5, 30, 45 and 60 degrees. Or other angles if you want to get fancy (72 degrees if you want to make a pentagon, for example).
19 mar 2023 · I have tried various methods for maintaining the 90-deg angle of a "T" joint with mild steel, say 1/8-inch thick. My best results have been obtained when I was able to rigidly clamp the pieces at 90 degrees, then: Tack one side, allow to cool, reverse the clamping, tack the other side.
Here's an old school corner clamp fixture used for welding 90* tubing and angle iron. This design has been around for ages. I didn't see it on the site so I thought I'd do a quick instructable and snap a few pictures. While a corner clamp can be bought, good ones can cost up to $100 or more.
12 gru 2022 · In order to make a 90 degree welding clamp, you will need the following materials: two metal plates, a welder, and some wire. The first step is to weld the two metal plates together at a 90 degree angle. Next, you will need to take the wire and wrap it around the joint between the two plates.
12 lut 2023 · Clamp the angle iron in place: Secure the angle iron in a vice or welding jig to prevent it from moving during the welding process. Tack weld the joints: Use small tack welds to hold the pieces together before making a full pass, ensuring they are aligned correctly.
6 lut 2015 · This Northern Industrial 90 degree angle clamp is made of cast steel with slotted base mounting holes and copper plated screws to help withstand weld spatter. The jig should hold materials up to 2 3/8 inches.
I always had the best luck with a simple heavy plate and some tubing tacked on--something like a 16" square made out of 3/4" plate. Torch the corner out so you can weld all around your parts when you jig them up. I've tried those 90 degree clamps, but they're so finicky and a bit gimmicky.
