Welding of A2-70 Bolts
Welding of A2-70 Bolts
(OP)
Good Day
M6 A2-70 bolts (ISO 3506) are tack (spot) welded using a 1x2mm fillet weld 6mm long onto a 316 SS plate to prevent rotation during bolt up. Is there a concern regarding the degradation of mechanical properties of the bolt for a service life of 30 years?
Any suggestions or further reading will be appreciated.
Kind Regards,
Richard

I'll get back on that one
And this one too...
Yes, I'm concerned about chromium depletion in the heat affected zone
