How I Mig welded a Bandsaw Blade

[@johngurney1069]

hi watched some videos on how to join blades copied them exactly as shown the blade joint lasted no more then 2 minutes, watched your video, pulled out my mig and wow very easy and still cutting steel with it. after wasting all that time and effort like cutting the ends square, bevelling them cleaning the blueing then hoping the silver solder holds never again i will be using a mig always and the blade i welded was 1/2 inch wide, thank you great help,

Glad it worked for you!

Thank you for demonstrating that repairing a bandsaw blade by MIG welding is viable. I am fairly new to using a bandsaw and to welding. I have broken two blades that are still fairly sharp. I really don't want to keep buying new blades if I can weld the old ones back together. I'm going to go with flux core since I don't haven't set my welder up with gas.

I was having a hard time buying silver solder & bought some solder that was Tin, Copper & silver but not sure if that would work good being, it is lead-free and I was worried about it heating up while cutting & come back apart since lead-free solder melts at a lower temp. Think I will try this way out first. Thanks for the tips!!

I have to try this..your method is same as shop uses to make custom cut blades. I have a blade that was made a bit too long,,cant tighten blade on pulley so I'll shorten the blade.

Thanks much, this is exactly what I needed.

[@masonryjoe]

I wonder if tig would work well, one would think so ?

[@longsspeed]

Would be would a try for sure.

From my very vague understanding bandsaw blades are high carbon. Our typical mig wire is mild steel unless you buy hard facing wire (I believe). I might try my hardfacing wire, then harden the welded joint, after hardening I believe tempering by heating it up to a specific temperature and letting it cool slowly. Allegedly this will make the steel somewhat hard but also springy. That's the most preferable properties for a blade. Spot welding would probably be good too because like tig you'd be using the steel in the blade to fuse it together... My untested theories at this point.😬

to much thought just do it, i did and the blade is still working fantastic idea

[@crazyDIYguy]

@@johngurney1069 mine blew apart, I brazed it and it snapped right next to the braze. Definitely sucked.

[@johngurney1069]

@@crazyDIYguy have since mig welded another blade just encase first blade was just luck but second blade used copper under blade when welding and after welding just warmed up blade not to hot, all worked great

[@petrusjohannesnel9934]

My friends asked me to have a try with MIG Weld on their broken blades. Due to safety concerns - I hesitated Thanks - for video,- I gonna try now

[@longsspeed]

The blade is still together. I replaced it cause it got dull!

Hello. I'm just curious if it is possible to weld a bandsaw blade using oxy-acetylene?

[@longsspeed]

From my understanding it’s the preferred way and I believe you use silver solder with it. I didn’t have that so that’s why I tried this way.

[@jamaicafrancisco_]

@@longsspeed thanks a lot.

[@newfoundlandsawmilling9023]

How did the blade hold up. Ive been using silver solder for my sawmill blades but looking for another way.

[@longsspeed]

Great. Still working and I’ve cut a lot of steel with it and pushed it pretty hard. I should have ground the back down a bit better as it bumps over the wheels a bit. But doesn’t seem to bother it.

[@newfoundlandsawmilling9023]

Good news. Im going to give it a try on a sawmill blade.

[@crazyDIYguy]

@@newfoundlandsawmilling9023 how did it work out?

[@montwolfman]

I would have used a copper or brass plate under the blade to prevent a blowout.
