[TheForge] Repairing power hammer dies

[Ralph Sproul]

	Cameron,  Thanks for this info on the die repair.  I have a chipped die and
will try this.

	It sure make sense that a medium carbon spring wire would lend itself to a
tough but not to hard repair in tig welding - I see that 5160 is a
low chrome alloy for springs.  So a tough repair with a chrome (being that
it has good impact qualities makes a lot of sense) should be a good one
for impact and toughness.
	Just curious as to your results - what is the largest repair area you've
done on a die?  about a 1/4" square - or something 1/4 x 3/4 as like
 a chipped edge?  Or have you filled scale abraded hollows with good success
as well?

Thanks,

Ralph

On a set of little giant dies I've repaired chips by tig welding the
void using an uncoiled spring (~1/8" diam wire) as filler material.
I'd guess most springs are 5160 -ish in composition. I've had
surprisingly little cracking of these repairs.
