1.75x1.75x1/8 Butt weld Questions

admin

I am making a swingout tire carrier for the Jeep I am building the kid, and I have  a few questions prior to welding things up. I will be using a Lincoln PM215 to do the welds with solid wire and C25 gas.1 - Do I need to bevel the edges on the 1/8" square stock prior to butting it to another piece, or will I be able to get sufficient penetration that it is not necessary?2 - If I do need to bevel, how much of a land (I believe that is the correct term) do I leave? 1/16"?3 - To prevent distortion, do I tack one side, rotate 180, do another, then tack the other two sides in a similar fashion before running full beads?Thanks for all the help. With the price of steel these days I don't want to make any mistakes if I can help it.Mike
Reply:yeah i'd bevel the edges and then clean it again..tack the ends..make a small tack in the middle flip it over and tack the middle again..small welds about 1" per weld..start at the ends and work twards the middle.....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:Thanks for the reply zap. When you say tack the ends, I do all 4 corners, then tacks in the middle, then complete the beads from the outside in?Thanks,Mike
Reply:is there any way at all to post a pic?i'm getting confused as to what your doing.. but you have the order of finish correct ...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:Zap,I am building the swingout tire carrier shown here:The vertical part of the A-frame needs to be butt welded to the horizontal member. That is the joint I am talking abbout, but I guess the weld process would apply to the 45 degree gussets as well.Thanks for all the help and patience,MikeLast edited by Wannabe; 08-10-2006 at 04:54 PM.
Reply:ok now thats better..i did not know you were refering to tubing..i thought it was flat bar..yeah just tack the corners and on the fourth tack..thats where the full weld would begin.. go around the whole tube in one motion...its best  to get all the pieces together and tack the unit and then make sure that it will go where you want it the first time..that would suck having it all welded and oops...somethings wrong  i only did that once..and getting my stuff apart is a major hassel.. ...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:Great,Thanks for the help zap.Mike
Reply:One last question (hopefully):Since I am bevelling the end of the tube (down to a 1/16" land), do I still set the welder for 1/8" (thickness of the tube), or do I lower the settings so it doesn't blow through?Thanks,Mike
Reply:I would leave it on the 1/8 settings for your machine. But thats just me
