Re: Broken Skeg?? Force 125
The Key to any weld or braseing ,soldering is haveing the area very CLEAN. Flux is used to keep impurities in the sourounding air away from the weldment.
But yes it can be repaired useing a flux core Mig gun,( just not a clean weld bead after) my concern is the heat on cast alum. Its a process that needs to be done by a welder that has had experence in alum. repairs and cast alum. Cast anything has more pores and this allows more impurities in the base metal. You set the heat range on a MIG gun on the mach. then go strike an arc, a TIG is controled by a foot petal and you can strike an arc at a lower temp and bring it up to the welding point. Neat, clean bead .
I have seen guys strike an arc and just keep going and then (because the puddle looked good) then stand back and scrach there heads wondering how it got so warped out of shape. The first thing out of them was "I have Never Had Anything Like This Happen To Me Before) I just walk away saying "well I guess you haven't been welding long then".
Dont get me wrong, wire feed duel shelid , inner sheild, or just sheilded gas has its place, Me ,myself and I just prefer tig on items like this.
A lower unit is hollow to allow seals ,gears ect. and must not be warped at all or it will not seal and your back to needing a lower unit houseing. If you get so much as a small "bubble" the houseing the gears and seals will not go back into place. There are welders out there that can weld it with all the seals and stuff inside but your going to pay for it. First thing a welder will tell you is they can't garentee it wont warp.
