Weber Q grill cracked hood

admin

I emailed Weber telling them mine was cracked, and asked what the hood was made of, and if it was weldable. I didn't get an answer to work with. They said I might be able to tack it, but didn't say what it was.My guess its aluminum. Anyone know for sure, or try and weld on it? Thanks
Reply:Did you try a magnet test? I have looked at those grills several times, I always thought the weight made me think it was steel.

Reply:most of the grills I see are some sorta cast aluminum.   A magnet or a grinder would tell. Either way I'd say weld it!It seemed like a good idea at the time!
Reply:Its non-magnetic, it must be cast aluminum. I thought maybe someone has repaired one. I'll try PP MIG.
Reply:Cast aluminum. Perfect candidates for spool gun repair.

Reply:I've repaired lots of aluminum things from wheels, motorcycle parts, boat motors, dump trucks and aluminum is like a sponge, it'll soak up oil, carbon form exhaust and it will have pockets of impurities.  Best to clean it with a carbide burr or grinding wheel, then I run the TIG torch over it till its clean and shiny then brush with SS tooth brush, then TIG weld both sides.It seemed like a good idea at the time!

Reply:Not being an expert with aluminum I’d venture to say you might have good luck cleaning the coating off “ ceramic ? “ followed by some of the aluminum brasing rod or some other higher temp brazing rod.  Using this meathod you won’t burn through the cast aluminum and  it might just hold up to the heat from grilling but hard to say.  How hot does that grill get when grilling with the lid on.  Other alternative is keep browsing cl, OfferUp, eBay and the likes for a cheap replacement grill if you are dead set on on keeping this grill.  Kind of reminds me of the older Hibachi grills.  If it were me, I’d stick a fork it that one!  Looks like a goner imo.  OK time for the experts to bash me for my lack of experiance and knowledge.Last edited by N2 Welding; 2 Weeks Ago at 11:08 PM.Lincoln, ESAB, Thermal Dynamics, Victor, Miller, Dewalt, Makita, Kalamzoo.  Hand tools, power tools, welding and cutting tools.
Reply:The clamshells are actually pretty good but the quality of the cast grills has gone down a lot. I’ve had a couple. I wouldn’t bother to fix that, it still works. MTTIW.Do not believe everything that you think.

Reply:Muffler tape?
Reply:I might play with a couple things, but the muffler cement sounds good also. It still works just fine, a little smoke leak doesn't hurt anything,  The back does look pretty nasty, but inside it has a lot of life left in it.

Reply:Not sure if it exists but if so high temp jb weld is another option.  JB weld sticks and works pretty good on cast aluminum.  Works on cracked engine oil pans.Lincoln, ESAB, Thermal Dynamics, Victor, Miller, Dewalt, Makita, Kalamzoo.  Hand tools, power tools, welding and cutting tools.
Reply:Man that's totally doable.  if it was in the SW Florida area I'd o it.It seemed like a good idea at the time!
Reply:You should stop-drill all those cracks so they don’t spread…Do not believe everything that you think.
Reply:That top sells for about $70.00 new.  I’d think you might be able to find a good used one for about $50.00 or so.Lincoln, ESAB, Thermal Dynamics, Victor, Miller, Dewalt, Makita, Kalamzoo.  Hand tools, power tools, welding and cutting tools.
Reply:you will probably have to drill stop the crack.  When you hit it with heat it will probably take off like a ruptured duck for parts unknown.  I messed with an older grille that I had and found it to be some type of cast aluminum.  Get hold of some aluminum bronze filler and tig it from inside after cleaning.
