Ripper 37 Blades breaking on weld

[Youngstu]

Hi. 

After having my third ripper 37 blade (on Woodlands HM130) snap on the weld I was wondering if anyone else had had similar problems.

All three have been from the same pack of blades bought last September. Fortunately none have gone early on, but after quite a bit of cutting, but not at the point I was ready to change blade yet. Tension is set right, everything cutting well and all of a sudden... bang!

Thanks

That’s a shame.

Try heating the weld with a gas torch till its a cherry red and let it cool slowly . Don't quench it . ( before mounting the band of course )

Does sound like a annealing issue or lack of.

Three bands since last September? Most folk go through more in a day. These three bands have seen ''quite a bit of cutting', which implies sporadic use. Id imagine they have been work hardened and is nothing more that user error. Stubby is on the right path I feel. If you're gonna baby three bladed for the best part of a year then perhaps a schedule of PM is needed?

Blades bought last September. 

Three blades have snapped on the welds. 

Out of 30+ blades I've used over the last few years these are the only ones I've had snap/break. So after today's breakage I thought I'd see whether anyone else on here had experienced similar issues as I thought I remembered seeing someone discussing similar but it may have been on a woodland mills FB page.

I'm not really up on metal treatment etc, would I be right in assuming that this would improve a poorly finished weld and do no harm to one that should be ok anyway.

Thanks very much for the helpful responses Stubby and Khriss.

Define "quite a bit of cutting"  from an almost one year old blade,

Sand keeps the draft off, slowly slowly. Mass produced blades always will have a few odd ones( bloke goes fr a piss, etc) K
