      "Welding" pot metal to steel

      Wanting to weld my 69 Javelin front and rear fender extensions (pot metal) to the fenders. What is the best way to do this, so that the joints will not crack in the future?

      Thanks,
      Mike

      Maybe you can do something like this to get an idea.

      I believe this is what they use.

      I would go to a site like http://www.allmetalshaping.com/index.php and see if somebody can copy them in sheetmetal. I don't think anything else would give me the smooth and seamless results I'd be looking for that would last.

      Not going to work, different expansion rates, it will always separate at the joint.

      Powder coat or paint them the same color and attach in the normal fashion.

      i have seen all sorts of show cars doing this, looks great but how will it last over time as paint and body work will always shrink and swell thats why those Eleanor cars look terrible all the time i ever saw one. these extensions on any old car fit like pure garbage most of the time no idea how they manufactured this stuff so poorly from the get go. I do know some welding gurus can weld to pot metal with special tig or brazing rods but i never saw this done

      I've never seen anyone weld "pot metal" It's cast, and not a very good material either in my opinion. Listen to Don Hutton on the 3M 8115. This material has been mentioned several times before, and I use it for just about everything. I'm serious, before I retired I used it to glue stainless steel sinks to the underside of granite countertops. Never had one to come loose. Had to destroy a vanity sink once because the customer decided to change the sinks after I had it glued up.
