Default Part 2 how to clamp exhaust tubing

Please show pics or post how you hold exhaust pieces together for welding.

I do all the fabricating but do not weld. My welder is very good but it seems to me he lacks a shop/tools to hold stuff and do a proper job.

If I can provide him with pieces already clamped it would be a help.

Im kind of a newbe with exhaust systems....what is the protocal for clamping round stuff....(2.5")

Usually held by hand and lightly tacked every 90 deg for me.

This is the current project. Can one use masking tape to hold while tacking?

nice tight gap....tape wont hold it, just have someone hold it square and then tack it.
If it is being tig welded it will be even easier. A good welder could do that by himself.

Sounds like you need to make a fixture.

You could try to make one out of wood. Have the flange bolt to it and the other side surround the tube.

Very nice fitI would just number the pieces; you are saving someone a lot of work & hopefully they account for that. I would enjoy welding that.

Ive used hose clamps before. Just weld right through the damn thing to tack it up. Cut the excess off and finish welding. Thats not usually needed though. Just get a second pair of hands to positioning it and then tack it.

last time I welded tubing I held it while tacking it. How well do MIG welds work for an exhaust?

Grab a hose clamp and drill as large of a hole in it as possible in three positions spaced around the circumference. Tighten the hose clamp across your joint and tack weld right in the holes being careful not to weld the hose clamp to your work. Should work fine for most applications.

If you have enough room for a clamp you could also use these: http://www.summitracing.com/parts/SUM-693330/

Or even make your own.

I use a piece of angle iron on an adjustable "A" frame stand, put the two pieces in the V and support in position to tack, use hose clamps to hold steady if needed.

Strong hand clamps with the optional swivel jaws. Easy and quick but not super cheap.
