Hi
A friend has asked if i can 'recover' the work done on an aluminium cover plate by their usual welder. The cover is purely a cover with no stressed parts etc. It is about 26" x18" and 1/4" thick cast aluminium. It is from a bomag type road roller and covers the gears on the side so can get a bit of rough treatment. As it is its scrap and a new one is £600 ish.
The 'usual welder tried to mig it but clearly has not pre heated it so the weld has cracked. Then gave up and said it couldn't be done.
I think it can be done with a very good clean and pre heating and patience.
I have looked on the miller website and it suggests a starting point of....
2.4 Tungsten
2.4 filler
190-220 amps
I have a tetrix 230 ac/dc machine and 5356 and 4043 filler.
Any helpful advice on anything so far and balance and frequency suggestions.
