yo2001 Posted March 22, 2009 Share Posted March 22, 2009 I was hoping someone can teach me few things on the general rule how to seam weld the chassis. How long does the weld has to be? I've been running a bead about 1.5 to 2 inches. What about the spacing between the weld? I'm using TIG to weld, I guess it's acceptable. Do I need to run a second bead to convex the bead? Here is a picture of the weld. Let me hear what you guys think. Thanks Quote Link to comment Share on other sites More sharing options...
locodrftr Posted March 22, 2009 Share Posted March 22, 2009 Hmmm i think most people do spot welds every inch or so kinda like... ---0---0---0---0---0---0 as opposed to ---0000000---0000000--- lol dont know if that helps or not but its done that way to as to not cause distortion in the metal from the excessive heat from a full bead. I assume you are trying to stiffen up the chassis right? If so then go with the stitch welding, thin gauge sheet metal warps like crazy. If you must weld a full seam the go with the stitch welding and keep jumping around to avoid overheating the metal and making it warp kinda like.. ---0---0---0---0--- then --00--00--00--00--- then -000-000-000-000- finally 0000000000000 then u have a full seam.... hope this helps.

JMortensen Posted March 22, 2009 Share Posted March 22, 2009 Weld an inch, skip two. I started at one inch welds one inch apart and was told to spread them out:http://forums.hybridz.org/showthread.php?t=95739 I wouldn't do it with a tig unless you have a lot of time to kill. I'd also STRONGLY recommend building a rotisserie. When you start doing all the frame rails underneath you're going to want one bad. Quote Link to comment Share on other sites More sharing options...

I guess I should shorten up the bead and add few extra. Right now, all I have is time and tig welder. lol I can go borrow my friend's millermatic if I must. The rotisserie is to come, right now I'm just trying to weld up what I can reach. Quote Link to comment Share on other sites More sharing options...
