is there anyone doing alloy welding , i need a water pump housing welded a small hole ,not looking for a freebie just looking for someone in the perth area. any info would be very helpful
yeah no worries .. just go to a workshop with a boiler maker & he will weld it for you . Too easy mate 
cast alloy ,its a water pump housing off a toyota ,cant get a new one so need to give this one some attention
Ahh , I see. Thier cast rubbish and dont weld too well at all. Is the hole caused from corrosion? If so welding would only blow the hole bigger and not penetrate at all. You could just try it with the MIG but I doubt it would last very long.
My advice would be to hunt wreckers or if not hit up toyota. Surely there has to be something around if its a Toyota?
If still no go give me a PM and I'll machine something up
Ive used aloy welding rods that i bought at a boat show once..using just propane gas. They work a treat, they are actually zinc based with a lower melting point than ally.
If the part is damaged is from corrosion you might be chasing your tail a bit.
thanks for the replys . its a timing case cover that has the water pump bolted to it . its not leaking but the water jacket that goes to the block has corrosion and it is only a matter of time before it starts leaking . i am reboring and rebuilding the motor as i do a lot of miles in the bush and want to fix any problem before it shows up . . the alloy is not thin that has to be welded . thanks for the offer kearnsy but theres nothing to machine just need a some ally welding
only a six pack . i would thought at least a carton and $ cash$ , but your on holidays . i guess i will have to do it the old fashion way and have a look in the phone book for someone interested in $100 for 5 minutes work . these windy days really make it hard for those of us who work to get any thing done ....
get it really clean with degreaser ,a non ferrous wirebrush, then acetone, then fill with a epoxy metal or even just araldite. I repaired a Hiace thermostat housing that way years ago on the Nullarbor and bought a new one when we got to adelaide. 250,000 km s later the new one was still in the toolbox 
Dunno about araldite - it soften considerably at 80deg ish and fails completely at 100 - 120 (?)
Maybe quicksteel or similar
you could try some of the "Devcon" products I have seen them hold up in some pretty agressive enviroments.I've just used some a few weeks ago (liquid ali) to reclaim an old bus waterpump manifold along its sealing face gave it a quick skim on the mill and seems to be holding up,the owner of the bus has a few more old Perth "MTT"buses and has used it on them with good results.Still would source a replacement for long term peice of mind.

Devcon is good but once applies from a welders point of view will create slag inclusions and unwanted porosity.This unwanted deposit will make it virtually impossible to weld.
DEvcon is good for non ferretic cast metal.
Dont use devcon on ferretic metal.
(metal which has iron in it.)
