cyrus Posted February 24, 2006 Share Posted February 24, 2006 People make a big deal out it, but once the welder is dialed it is easy. Quote Link to comment Share on other sites More sharing options...
HizAndHerz Posted February 24, 2006 Share Posted February 24, 2006 You are an inspiration to all of us welding newbies! I'm suprised to see no references to http://www.autobody101.com on this site. There's a great begginer's guide to welding and painting that can be downloaded there. The forums are a great resource, too. Check it out if you have not!

JMortensen Posted February 24, 2006 Share Posted February 24, 2006 I stitch welded mine, and that is considerably harder, especially underneath. Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted February 24, 2006 Share Posted February 24, 2006 Cyrus, you have your car apart again? Stiffening the chassis I suspect Quote Link to comment Share on other sites More sharing options...
Guest Trudge Posted February 25, 2006 Share Posted February 25, 2006 Doesn't spot welding like this promote rust? I mean, on the back sides of the spot welds the metal is bare and you can't get to the backside to paint or otherwise protect the metal from rusting.

Chewievette Posted February 25, 2006 Share Posted February 25, 2006 I have always been told that fully welding a unibody is the easiest way to stiffen it, but I'm curious would that take out too much of the flexibility?(aka promote stress cracks) Should I spot or stitch weld it and call it done? Thanks. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 25, 2006 Share Posted February 25, 2006 Stitch welding is the way as far as I know. I've never heard anyone espouse the benefits of spot welding and full seam welding is supposed to be less stiff than stitching, but stitch welding is pretty common: http://www.betamotorsports.com/services/index.html (click chassis and suspension) http://www.rally.subaru.com/rally/servlet/CarBuildingDetail?part=1&imageId=6 Quote Link to comment Share on other sites More sharing options...

I mean' date=' on the back sides of the spot welds the metal is bare and you can't get to the backside to paint or otherwise protect the metal from rusting.[/quote'] any welding is prone to rust. you must cover it with a sealer/primer/zero rust/por 15 etc because it will start to flash rust in about 1-2weeks.

Guest Trudge Posted February 25, 2006 Share Posted February 25, 2006 you must cover it with a sealer/primer/zero rust/por 15 etc because it will start to flash rust in about 1-2weeks. Maybe I'm being overly paranoid but..... What about the bare welded area between the fender well and frame rail flange. I mean, inside the seam where the fender well and frame rail join/touch. You can't get into that area with sealer/primer/zero rust/por 15 type products. The sealer might seep into those areas but you can't be sure because you can't see it. How do you protect the "Back Side" of the weld? For example, I welded up the holes in the fenders, doors, and rear quarters that were from the body side molding which turned out to be a rookie mistake. I painted the outside but forgot about the backside of the weld and rust began to collect inside the fenders, doors, and quarte panels where the backside of the weld was not protected. I have now sealed the backsides but with the type welding shown in the first post, bare metal is created from the weld that you can't reach.

Brad-ManQ45 Posted February 26, 2006 Share Posted February 26, 2006 I wil back jmortensen on stich welding. Any welding will cause the metal around it to get brittler. Full seam welding is not a good idea because then you have brittle metal all along the weld seam, whereas with stitch welding, there is a lot of strong metal left. Can't remember the site I read all this off of, but there are definite reasons to go stitch welding route. Quote Link to comment Share on other sites More sharing options...
