ZION Posted June 7, 2013 Posted June 7, 2013 Hi allLooking to fix a cracked frame,whats the correct welder to get. Aluminum specific?Low cost would be good aswellhttp://www.e-weld.co.za/images/stories/200a%20pwm%20june%20special%20end%20user.jpg This do the job ?Ty in advance
pastapouch Posted June 7, 2013 Posted June 7, 2013 nope, its a specialised job, alu has to be welded in a vacuum free from oxygen if I don't have my brains scrambled. Very tricky to weld.
Baaisikilist Posted June 7, 2013 Posted June 7, 2013 It neads proper heat treating or the welds just re-crack. Tried having my rear triangle alu welded at Castweld, lasted a week then cracked worse than before. Ended up buying a new swingarm...

Christie Posted June 7, 2013 Posted June 7, 2013 Cant fix an alu frame by welding it, it will crack again at or close to the weld.
ZION Posted June 7, 2013 Author Posted June 7, 2013 Ty for the replies.So there is no other way to fix alu frame ?

Guest Omega Man Posted June 7, 2013 Posted June 7, 2013 (edited) Ty for the replies.So there is no other way to fix alu frame ? No that's not true. I've had an Alu frame welded and I rode it for a good while before retiring it. Take it to someone who knows what they are doing and you might luck out. You might also strike out like the guys above depending on where the crack is. If it's on a suspension linkage or head tube for example you might want to steer clear cos a break there could lead catastrophic frame failure and that will ruin your day. Don't spend too much money cos there's every chance it could crack again. Edited June 7, 2013 by Omega Man
Overlord Posted June 7, 2013 Posted June 7, 2013 nope, its a specialised job, alu has to be welded in a vacuum free from oxygen if I don't have my brains scrambled. Very tricky to weld. Huh? Do alu welding everyday and have never had to do that. And no not just a quick weld here and there. Some of the jobs are tanks that transport flammable liquids. Certification is needed on welds like these so its not joe average welding.

DIPSLICK Posted June 7, 2013 Posted June 7, 2013 Please direct me to the right one Buying a welding machine to weld a crack( and u don't know how to weld, I am assuming this since you asking about a cheap and nasty welding machine ) makes zero sense, there are many places that will weld that for R300 and problem solved
Sniffie Posted June 8, 2013 Posted June 8, 2013 Tyvm for the offer,it is a friends bike im trying to get back into mtbing , need to fetch it. Cracked at join between seat tube and top tube. Would Pros weld and heat treat again ? Sounds like a Giant Anthem? They have lifetime warranties on the frame and normally don't argue about replacing.
ZION Posted June 8, 2013 Author Posted June 8, 2013 @ZIONTY for replyThats the price of a new dual frame ,tryna get the dude back on bike with minimal costs.So no cheap decent welders. TIG welders even more expensive ?

My stoop awnings need a weld here and there,think it will pay itself off. I have welded before ..well stuck metal together with bird poo.... .The way i see it is couldnt service my own bike before now i can,didnt know how to anodize parts.. now i can...Sure i can learn to weld too ..But i hear you 100%
