Hi Robert
Looking forward to hearing how the welding was done.
I have used oxo acetylene with fair success in the past but I do not have access to tig or mig so maybe these are ether for blade repair. I also do stick welding but this would be too harsh for blade work.
When repairing breaks, I found it no real problem when working at the spine of the blade but where the blade becomes very thin Towards the cutting edge I found it quiet difficult not to burn through the blade.
Did you find differential cooling a problem, I did in so far as I had to heat the blade either side of the weld to help ease the contraction of the metal from forming cracks.
Best regards
Ken
