I have an old buzz saw blade with a 3" crack in it. Any ideas on how to weld it would be great thanks.
Reply:UH, You can't and then spin it. It will come apart! If you are going to use it, then go to an auction and buy another.
Reply:That's what I thought .. But I was told of two different ways of doing it. 1. put a bevel on both sides, pre heat, weld, post heat. 2. bevel both sides and use heat sink and use a filler with nickel.

Reply:make it a nice wall hanger before you become a victim of flying metal....spend the money for a new blade............Of all the things I lost I miss my mind the most...I know just enough about everything to be dangerous......You cant cure stupid..only kill it...
Reply:High carbon steel, metal fatigue, a recipe for disaster. Not that it couldn't be saved, but at what cost? Anneal before welding , weld with a low-hydrogen process, grind, re-heat treat, balance and tension.  Woof!"USMCPOP" First-born son: KIA  Iraq 1/26/05Syncrowave 250 w/ Coolmate 3Dialarc 250, Idealarc 250SP-175 +Firepower TIG 160S (gave the TA 161 STL to the son)Lincwelder AC180C (1952)Victor & Smith O/A torchesMiller spot welder

Reply:Can it be done?  Yep.Should it be done?  Nope.These blades are usually around 45-50Rc and over hardening is an issue.  You can anneal the welded area to bring the hardness back down, but do you have the hammers and anvils/rollers to re-tension the blade?  New blades like this are generally under $300 buy a new one - those savings are not worth someone getting seriously hurt or killed.BradFulcrum Saw & Tool
Reply:Where you located ?  I have one you can have , sharp and great shape.  If you are close let me know and I'll measure the arbor and diameter.
