Has anyone built a band saw blade welder?
I have a small portable spotwelder that I tried welding blades with. I just clamped the blades to the sides of the electrodes and was only able to get it to weld one time.
When I handeled the blade the weld cracked.
(didn't realize it had to be annealed)
Being that real blade welders are going for more than I can afford on Ebay. I want to build a jig of sorts to connect to the spotwelder for making band blades. I'll have to experiment with annealing time.
Has anyone made something like that?
Any ideas that would make it simpler or better?
I would like to be able to weld blades up to 3/4" wide.
The spotwelder outputs a maximum of about 2200 amps at about 1.5 volts.
Thanks in advance
BTW when I need to forge just one item I can sometimes use the sotwelder to heat it in seconds to red yellow or white heat, depending on the thickness. The largest I tried was a 1/2" nut (3/4" AF) to weld it to a piece of threaded rod. Heat it and hit it on all flats on the anvil. Then arc weld on the end and grind smooth. Takes less time to do it than to describe it.
