Question

admin

I have two dumbbells to weld for an athletic club, one 80# and the other 100#.  These are cast in the shape of a hexagon, about 5"W and 7"H w/ a knurled mild steel ( I think) 1" handle separating them.  These are dropped by the muscle heads in the weight room onto concrete, even though we have a rubber pad on top of it, the constant dropping has shredded it!  These are connected to the cast iron by a collar that the 1" runs into.  Someone welded one and it broke off the cast completely, the other was repaired w/a liquid metal of some kind and it broke also.  The question is, can this be welded w/mild steel stick, cast rod or brazed.  I have an AC Century that does a great job w/stick, I also have a Lincoln 175 handler that may not be big enough and have an oxy/acet. set too, with a variety of tips and blow pipes.  I would like to  weld these and not have them break in the future.  I cannot send pictures w/o waiting for an hour or more for them to upload since I am on a POOR dial-up!  The handle on the 100#er is even bent!  Some of these guys work out with two of them at once!!  The 120#er seems to be ok!  Any help?

Reply:I would pre/post heat the cast with the oxy torch and stick weld it with nickel cast rod.  I've had good luck with that method for welding cast to cast and mild steel to cast.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
