birmabrite is a mix of aluminium and magneseum and i wouldnt attempt to weld it if i were you unless yer use a spot welder and leather it good n proppa as exessive heat can set magneseum on fire ( remember the pretty blue flame off the metal in chemistry )
just be bleddy carefull
way back in 1971 when Rolls Royce aero went tits up, my old govner sought engineering work where he could.
I ended up profile turning magnesium wheels from castings for team Lotus racing. they looked like an hour glass with a very small middle like a waist.
was told to HURRY UP and dont fap about clearing all that mag sawarf from the swarf trays...............................................................
WHOOSH it all went one day...
filled the shop floor in seconds with acrid white smoke..
it self ignited through friction of the cutting tool..
firemen came and put wet sand on the glowing embers...
WHOOSH and crackle it then went again... lol...
november 5th has never quite matched that day.. lol..
I used to repair Rolls Royce Gas Turbines (very similar to the Aero Jet engines) and my old work burned down when a Magnesium case in the store ignited then caused a heap more to combust.
On the other hand they used to weld them all the time. I'd guess that's because it's safe enough to weld as the argon shields the molten weld pool from oxygen.
Cheers for all replies guys
