The metal in question is heavily pitted, but appears to be solid enough to clean up, no holes justr chewed up a bit. My question is can I take my mig welder and lay consevutive beads of weld along this area to build it up. My thought is to then grind it smooth and level w/ the good metal.
Whould this create any risk such as annealing the metal in this area? I think it would work but am by no means a very proficient welder. I can weld a nice bead on a flat surface though. | | | | | Joined: May 2001 Posts: 46 Member | | Member Joined: May 2001 Posts: 46 | I'd say you'd be OK.Clean the area down to shiny metal. Go slow,let the weld kool to touch between passes. Is the frame boxed or formed channel?(Edit;Did I read your Q. right?) If formed channel try to stay away from the edge of the flange 1/4 to 1/2 inch to prevent it from cracking.Otherwise you can put a strap on the back side of the flange. Have fun.  | | | | | Joined: Jun 2001 Posts: 27 Member | | Member Joined: Jun 2001 Posts: 27 | The frame is a formed channel, and the repair is in the rear area of the frame right where the Crossmember rivets in, I have removed the crossmember, and will be attmepting to repair the flat section of the C channel on the inside, The section that is 2" or so long. I will try to post a photo. What do you mean by cracking it along the edge, I think the edge is preaty solid I will be working in a 1/4" or so from the edge. | | | | | Joined: May 2001 Posts: 46 Member | | Member Joined: May 2001 Posts: 46 | Sorry,I didn't mean to cause any worry. My concern was you about placing a weld along the very very egde of the flange.Could cause crack to start Due to what known as the weld affected zone and the frame flexing.Usually due to extreme conditions.(Like,lone your truck to the dukes of hazzard.)  | | | | | Joined: Jun 2001 Posts: 27 Member | | Member Joined: Jun 2001 Posts: 27 | Well it was a little worse then I expected when I cleaned it up I could see a bit of daylight, So I got very brave and cut the small section out of the frame lower flange, I cut a peice to match out of another frame, and beveled the edges at a 45 and mig welded the patch in I have only done the top and will flip chassis over tomorrow to weld bottom. It looks good so far, hell my weld even looks pretty. What do you think, a disaster waiting to happen I hope not. | | | | | Joined: May 2001 Posts: 46 Member | | Member Joined: May 2001 Posts: 46 | I'm guessing it was rusted where the X-member came in contact with the frame. Just keep it under 120 mph in the curves.....should be fine  | | |
