Hardfacing chain?

admin

Just got a call today regarding hardfacing loader chains... What would be the best approach on a job like this? He mentioned the hard facing needs to be spot welded per the instructions to maintain base metal strength. I'm picturing getting a good ground may be an issue. The chains are large (roughly 5'x15') and weigh about 400#.  Is this a job to avoid? Time/material rather than bid it...?Miller Dynasty 200DXMiller 252 Miller 250xMiller Syncrowave 250Miller AEAD200 LegendMiller 375 Xtreme plasmaLincoln WeldPak 100Victor O/A
Reply:I would avoid it. Even if you have really detailed instructions from the manufacturer on how to do it without affecting base metal strength, in case of a failure you would have to prove that you followed them exactly which is not always easy.

Reply:I think he's talking tire chains, they are put together like a big chain net for more traction.

Reply:Never done it but I'd just do cost plus on it and get them to sign off after saying done to customer specification
Reply:Well, I passed on the job after discussing it with some other welding buddies. Sounds like it is a major PITA and I really don't need the work at this point.Miller Dynasty 200DXMiller 252 Miller 250xMiller Syncrowave 250Miller AEAD200 LegendMiller 375 Xtreme plasmaLincoln WeldPak 100Victor O/A
Reply:Loader chains are also used for snow moving work. It wears them a lot, as they are running on dryish pavement a lot of the time too. I've seen hardfaced chains in that application a lot.
Reply:As a young kid I built up truck tire chains.  I put small beads on the flats and they seemed to work ok.  No fractures and the links lasted as long as new.  I just used old reliable E 6013 :')  I would be more concerned hard facing links since they would be more prone to fracture if not done correctly.
Reply:I use to do Log Skidder Chains in my off time out in Northwestern PA/ Southwest NY.Lay them on a sheet of plywood, start at one end and slowly work your way through each piece.Of course you always had to repair and build up a bunch of worn out junk first as these guys hated buying new chains!
