Respect for Tool Welders

[vicegrip]

This is the kind of challenge a Tool Welder gets.
He welded it last spring , I just never finnished the milling.
I can't tell him what the alloy is ,
A tiny file scrape tells me it's 46-54 RC (crack-pot guess)
I don't want to file any deeper, for a better reading.
I can't tell him what the plating is.

I can ask for 48-52 RC
I can ask him to keep the part as cool as possible .
I can ask him to avoid melts adjacent to the remaining sharp edges.
I can ask for minimum build-up.

I also reasure him (as usual) go with your instinkts, and don't sweat it if it aint perfect.
I'm asking allot.

Here's the buildup.

He said the first filler gave him the eB gB's and whacked the little bit
back off...the second was keeper.

Here's the finnished repair

I can say by the feel and sound of the carbide end-mill
he aced the rockwell.
Infact aced the job as far as I'm concerned
:cool::cool:

Hehe....you'd love the stuff we weld, when we're done we can often have it 60-62 Rc. Skip the carbide milling, it's either grinding or edm for this stuff. Heat shrink around the weld area has to kept to under .0004", often it's closer to .0001, or .0002", so that we can often grind real close, then lap to blend it in.

Unfortunately, so much of it's proprietary parts (customer owned dies) that pics are out of the question.
