multi pass mig vert down

admin

Ok folks I really wanted to weld this 1940 chevy coupe's new brake linkage vert up;however, in hot-rod industry looks matter. A big also is that this was a major out of position weld. Not the best but for a multiple pass  mig I thought it was ok.  Customer would not take body off for the welding.. here it is .. multi pass vert down.Customer did not want to weld to bottom channel of frame...so any way thought I would share this one with the guys.....Mig vert up and down is a topic....and my point is, atleast in this situation it paid off.    My certs clearly want vert up.....; but looks matter..  and I believe this should be well enough being multipass to maintain structual integrety.Let me know what you Mig folks think,,,the fish eye technique, or the weeve pattern I choose.  weld it like you own it
Reply:Looks like you got it plenty good.
Reply:That looks great. A little thicker than I usually do vert. down, but I am a big fan of it. Crank the amps up a bit, get it going right, and carry it down. Nice job!! And not really a good place to try and grind downa nasty weld, so definitely the way to go in that situation.And then, after so much work...... you have it in your hand, and you look over to your side...... and the runner has run off. Leaving you holding the prize, wondering when the runner will return.
Reply:I should be quiet.  You asked for it.  I would never weld down on  a structured piece.  If that is JUST the brake pedal it may be ok as far as your weld looking.  Should have been done UP.My other criticism is you welded the wrong way on the frame and created a stress point to crack later. LOOKS do count.  It would look great done properly UP, but would still create a place to break.  That car has some HP to it, and when he "gets on it" are you sure it will be OK?I would have welded a plate to the frame the long way top and bottom then welded the brake pedal to the plate.  That is the master cylinder mount too right?See this thread.  http://www.weldingweb.com/vbb/showthread.php?t=11338TRY it your self.  DavidLast edited by David R; 07-19-2007 at 06:44 AM.Real world weldin.  When I grow up I want to be a tig weldor.
Reply:Yep seen  that thread before; hence, thats why I wanted to post this one.  I've done  those test too.   Hammered em and tested them with concern.And with proper prep work and beveling with MULTI PASS I never had a problem. Also with 92% argon 8% mix with spray and globular and pusled transfers.  Very familiar with AWS structural steel certs.Also this was not the cylinder bracket just pedal assembly and this was welded to plate from the Camaro front end conversion done by a previous owner.  This was a major concern of mine if this was welded to 1940 thin walled frame.The top was welded too horizonal flat. just no pics. More than one way to skin a cat!!Last edited by lewray; 07-19-2007 at 08:09 AM. weld it like you own it
Reply:I am not dead set against verticle down.  I use it occasionally my self.  It just depends on each situation.  The weld looks nice.  DavidReal world weldin.  When I grow up I want to be a tig weldor.
Reply:Looks OK to me..But I would have tig'ed it.. ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:Most of my vert ups looks like hand packed crap. I watch for and worry more about digging in and pentration than I do about appearance. If I'm pretty certain it'll be a two pass ordeal, I'll do vert up first then a verticle down will cap it off nicely. As nice as it gets for me anyway.
Reply:Sound point there... weld it like you own it

Reply:Who made the vertical uphill weld on the right? For vertical uphill, that is one for the books! Getting real close, anyway. If uphill penetration is too much, or you fear it being too much, turn the voltage down a bit and match wire speed, of course. John, my semi-automatic instructor was brutal!! "Do another one." ...

Reply:I don't see why you couldn't do vert-up on that.  You can make it look even cleaner going up and you will know the weld is strong.  Not trying to give you too much criticism, but on something like that you don't want it to break.I find myself putting welds down daily where I can't see where I am welding.  I am reaching up behind something and literally welding blind in a vertical up weld on 1" plate and having to wrap the weld and everything.  So it can be done.But anyways, it looks good either way.  Hey, if it sticks.
