The problem you have with any welding is the dissipation of the heat affecting the soldered ribs, barrels, hook etc. IF you place steel bars in the barrels, steel blocks adjacent to the welding area to act as heat sinks and perhaps wrap the barrels with a wet rag you SHOULD be okay.It really depends on the welders skill if he gets it set up properly and just runs a bead cleanly and efficiently you will be okay.Remember to prevent welding spatter with Mig. He'll know what to do.Good luck.
