TIG bronzing, by the looks of it, and a remarkably nice process it is to use.

I'll be having a go at some point. No real reason ither than I can, so I will at this point, but a good technique to have in the drawer

I must try this at some point too. I believe I already have the brazing rods in the drawer 
I also have Arc rods for cast iron repair. From memory I did use them once on a vice and they seemed OK. I suppose a dirtier process than the TIG brazing?
I'm also sure that I've been able to get regular mild steel arc rods and TIG filler to stick to cast vices before to build them up. Like this:

Out of interest did you use any preheat? I have done quite a few cast iron braze repairs with OA that have worked out well and still in service today. I have been trying my hand at TIG brazing for some more delicate repairs but struggle to get the SiB or AlB to wet out as well as mang bronze or nickel bronze with flux and OA. I'm finding I need to basically start the base metal melting slightly before I can get the bronze to wet out properly even if I clean/grind everything really well before hand.
Anyway great looking repair

You can use copper wire (stripped twin and earth)
Not as strong as Bronze but it works .
AC also works with the balance set at 10% cleaning .

I have had good success using the 99% nickel stick rods, cleaning the flux off them and using them as TIG filler. I bought out an engineering shop that was closing down entire 40 year collection of various MMA rods for next to nothing. I found 15-20kg of various cast iron repair rods in the mix, they didn't run very well as mma electrodes but after cleaning the flux off, work as excellent nickel TIG filler rods. I thought I should buy a few new CI electrodes and a 10 pack costs about 3 times what I paid for the entire load of old rods, I'll keep cleaning off the flux and using them with TIG for now, probably have enough to last me until I die considering the small amount of cast iron work I end up doing.
I'm keen on improving my TIG brazing skills as I think its a more gentle process than TIG nickel rod repairs. Though they both certainly have there place.

Thats useful to know! I have some high nickel mma rods and I must try them out as tig filler.
