Re: Chain Preparation for Welding

I like your style.........I would do this myself as well.....just like you have done....it looks great........but I would also do a couple of test links and wrap that chain around a tree and take a couple of runs at with my tractor.....just to sleep better in a blow

Re: Chain Preparation for Welding

I joined my chain using the same slotting method (the cutting of ‘V’s in the material has been around for centuries in kid’s puzzles) but on the long side of the link.

Then TIG welded it so a complete build-up of material to the exact size of original link with no shaping/grinding required. It’s hard to find the welded links on the chain.

I wonder why there is a perception that a post-production weld properly done is weaker than the induction weld on every other link in the chain. I’ve never used a big tree and a tractor to test the thousand links welded in the chain factory - I just assume they’ll be OK.

Am I being “cheap” welding two bits of chain together. Yes, maybe but I was given 20m of perfectly good, near-new chain and bought another 65m of new chain. Welding two links to join them didn’t feel “cheap”, just financially prudent.

Re: Chain Preparation for Welding

I have never seen so many over think such a simple task. I spent much of my life welding in refineries, This aint rocket science. weld the damn thing. BTW probly most pipe welds in the US use 6010 root and hot pass. Switching to lo hi (7018) to fill and cap depends on code and customer.

The brain surgeon said “I’ve never seen so many over-think such a simple task. I spent much of my life opening people’s skulls in operating theatres. This ain’t rocket science. Open the damn thing.”

Applies to Boeing 747 pilots, free divers, landscape artists, concert pianists, well, just about any specialist really.

Just saying . . . . .

I was an oil driller and our philosophy was "If it moves and ain't painted yellow weld the bugger down".
