Some-Guy Posted August 7, 2007 Share Posted August 7, 2007 I smashed off a chunk of bondo and found this hole on saturday.We were wheelin and I landed on a big ass rock and smashed the step so I just pulled them off. They probly can be repaired but I didnt like em anyways. So I ground it out and formed this piece of sheet metal and started to weld it in only to find my stick welder was WAYY to hot for this. Ill be finishing the welding job at work tomorow with one of our migs. Hows it look so far? keep mind this is the first time I have ever tried anything like this.

naviathan Posted August 7, 2007 Share Posted August 7, 2007 Looks decent so far. Stitch it in, don't try to run a bead or you'll warp it. Quote Link to comment Share on other sites More sharing options...
Some-Guy Posted August 7, 2007 Author Share Posted August 7, 2007 I was having a real bad problem with blowing through. Iam not worried about warping it at all since its already horribly warped and there was about an 8th of bondo on there anyway. Iam going to bondo it up and try and match the original shape as best I can. During the week Ill be starting on the other side since it has abit of rust bubbling coming in also.

v8dats Posted August 7, 2007 Share Posted August 7, 2007 looking good so far! Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted August 7, 2007 Share Posted August 7, 2007 Idk it depends on the metal there but I wouldn't run a bead, I would just stitch as much as possible alternating spots. Just mho Quote Link to comment Share on other sites More sharing options...
Careless Posted August 7, 2007 Share Posted August 7, 2007 you're doin pretty good. as long as the bondo is real thin, you can consider it a well done job. 1/8th is not much at all, and I think it will turn out in your favour =) git'r done!

Some-Guy Posted August 7, 2007 Author Share Posted August 7, 2007 This job should require less than an 1/8th of bondo Iam thinkin anyway considering I bent the piece of the edge of my bench with a hammer its pretty damn straight. I need to borrow some ones mig welder to finish since my work said I can not weld in the shop its an explosion hazard (my ass). Quote Link to comment Share on other sites More sharing options...
Sam280Z Posted August 8, 2007 Share Posted August 8, 2007 it may seem counter-intuitive, but try turning the heat up to help with the blow-through problem. The weld puddle will form very quickly with a smaller area. I have had good results with this approach. Sam Also, looking closely at the picture, it looks like you are getting most of the blow though where the metal is pitted. You might need to cut farther back.

Some-Guy Posted August 8, 2007 Author Share Posted August 8, 2007 Ill give it a go and If turning the heat up doesnt help Ill cut the pannel off and make a new one to go higher up which I guess is what I should have done originally. Thanks for the tip I never woulda though of that! Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted August 8, 2007 Share Posted August 8, 2007 I personally think body metal is too thin and soft to use high heat to prevent blow through, thats just me though. Quote Link to comment Share on other sites More sharing options...
Some-Guy Posted August 9, 2007 Author Share Posted August 9, 2007 Yea I cant make it work I tried moved the panel up 1/2" and I blew through pretty bad still I need to find some one with a mig or a tig machine. This stupid AC stick welder is making me MAAAAAAD. Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted August 9, 2007 Share Posted August 9, 2007 Ya but just lower the power and stitch it. If you just tac real quick back and forth at dif points for long enough you can use even the cheapest of welder. I have been doing all of my work lately with a mig 100 the cheapest welder I have ever touched lol, its horrid but it works. If you scroll down in my pics you will see what I am talking about. http://forums.hybridz.org/showthread.php?t=123172 Quote Link to comment Share on other sites More sharing options...
Some-Guy Posted August 9, 2007 Author Share Posted August 9, 2007 I tried low amps I was down to 70 amps with a 1/8th 7014 rod and it was too hard to start. lam going to see if we have some small rods at work tomorrow. hell I would be happy to use a horribly cheap mig right now! atleast it would do this job.

Guest TeamNissan Posted August 9, 2007 Share Posted August 9, 2007 I know its really hard with a stick welder, keep at it though. There is always the mig 100 too, cost me 100$ on ebay haha. Quote Link to comment Share on other sites More sharing options...
Some-Guy Posted August 9, 2007 Author Share Posted August 9, 2007 AHHH Ok I think I can do this Iam going to grind it all off tomorrow and start again I just need to get some smaller rods this 1/8 crap is too huge and at 70 amps I cant even lay a 1/4" bead. the flux goes every where like its a decent bead but then when I chip it off she looks like utter hell! Anyone live close to me that wants to lend me the use of their mig for a while???? Quote Link to comment Share on other sites More sharing options...
Sam280Z Posted August 9, 2007 Share Posted August 9, 2007 Oh jeez. I have to aplogize. I didn't read your post close enough and ASSumed you were using a mig. I would not attempt this with a stick. Maybe a lap joint, but definitely not a butt joint. Sorry, Sam Quote Link to comment Share on other sites More sharing options...
mikeatrpi Posted August 9, 2007 Share Posted August 9, 2007 I would cut farther into the car body work. Looks like you have some soft metal waiting to happen in the vicinity. Quote Link to comment Share on other sites More sharing options...
Some-Guy Posted August 10, 2007 Author Share Posted August 10, 2007 I cut up another half inch or so and removed that it should be into the decent metal now. No worries Sam I gave up on the high heat after blasting a few holes in! I got it mostly patched mostly nothing alot and I mean ALOT of grinding wont fix now haha.

Techtron Posted August 10, 2007 Share Posted August 10, 2007 Great job man! I rarely post either. The more you practice the better you will get. It seems like you are picking up things quickly. Take it one patch at a time and make small goals. That helps me when I start working on my project. When you are done the wheel wells you will be well practiced to make excellent work out of more visible bodywork. This is all possible with a stick welder. Use some small rods. I think the 7014 rods you are using are the easiest to start an arc with but the downside is they also have high penetration so this is prolly why you are burning through. I could be wrong though. Look at the site:http://www.metalmeet.com/forum/index.php? those guys will have lots of help to offer you if you need it. Good luck! Quote Link to comment Share on other sites More sharing options...
panachedk Posted August 10, 2007 Share Posted August 10, 2007 okay, you guys ready for a really dumb question? alright, on a body piece like that, if you stitch it in, how would you fill the rest of the gap (ie, the gaps between beads)?
