Edge delamination

Recommended Posts

Having some time at hand i decided to continue whit the " less air" pointers which worked out almost perfect.

But i have some concerns on the ricasso area where the weld dint stick even after centralizing the heat/flux and trying for a second time.

 

OK so this is my project, spingsteel, mild, edge of twisted tool damascus

This worries me, should a couple of days in some vinegar be the best approach ?

It's normal for steel not to take weld at ends like that. If you grind the crummy portion out and be ginger with the welds for the rest of the forging it should all be fine.

Grinding it out and adjusting your design would be your best bet. At this point it's near impossible to fix by rewelding.

Grinding will expose the mild steel to the edge, i need to give it another try ;)

Ah I see how you did it now, was thinking you did a San-mai blade. Collin is right though, welds near the end are usually the ones to give way first. You're going to have a very difficult time fixing that. If that happened to me I would just scrap the design and come up with something that will fit the usable steel.

for now i used a chisel to cut open the weld until solid. Need to do some forge modifications first then go for the second try after cleaning up the surface.
