So far from what I have seen, a laser welder is the wrong tool for the job. This requires penetration and if you are going to machine the surface again I really do not see any advantage at all to a laser. Tig is the way to go.

No disrespect meant Steve, but Ken Eversull who uses a laser weld, and Abe Chaber who says replacing the hinge pin is the only proper way to go, would disagree with you on the best way to put a gun back on face. Frankly, I'm confused as to the BEST way to do this as there are so many different opinions regarding this matter. I think the cheapest way to do it would be to tig weld and most expensive would be to replace hinge pin, but I'm not even sure about that.

as I understand it Ken uses a spray welding technique and has excellent results with it. Spray welding is not laser welding. I have stated that this is one way to do the job, not the only or the best way. I also replace pins and would usually choose to do so before welding the hook. Lots of ways to get it done. Which one is best? That remains to be seen, but I feel very confident in offering this as one of the methods we use in this shop to get the job done properly.

The best way is the way that is both most efficient and economic . It will also depend on the gun and how much work will be needed to do the job correctly and permanently .
There is no best way just that some methods better than others and some merely bodge jobs temporary to say the least.
I do not know how many guns I have rejointed but it must run into hundreds ,it sometimes seems that you spend longer deciding which way to do the job than you take doing it .

Thanks for sharing Steve. The jig is impressive. What about soldering on a steel shim? Is there a downside? I've never done it, but it seems like it would work fine with high force solder. Just curious.

Eversull uses a very expensive laser welder. No spray welding in his shop. Alot of high end gunmakers, here and overseas have bought into the laser welding method. I had a Brit gun put back on the face last year using this method, even under a jewelers loup you cannot tell there was any work done at all. There is a gentleman in Michigan that laser welds for the trade. Next to Eversull, he's the best in the business. Extremely precise work.

interesting, but I have had issues with laser welded filler bonding to the parent metal the one time I contracted out the work. Lots of ways to do things. I'm happy with my methods and I have heard nothing but good things about Kens method. The final result and a happy customer is all that counts.

This is an interesting subject Steve, and your procedure looks great to me. I am confused and I hope you can explain why your procedure is unsatisfactory for chopper lump barrels? I know the laser procedure is used on chopper lump barrels because Ken Eversull rejointed a gun with choppers for me by that procedure.

chopper lump barrels are joined using high temp silver solder. The silver solder will act as a contaminant when the TIG welder goes add his filler rod and it usually results in porosity in the weld
