A new welding method?
« on: January 17, 2005, 16:30:30 »
I'm sure we all get involved in welding, especially us Landy owners.   :lol:

I don't want to say where I heard this (some anti snoopers may already know), but this sounds interesting.

Steel has friction properties that can allow it to generate incredible heat levels.  Apparently, two pieces of steel, rubbed together in a vacuum, will weld together.  Hmmm.  Anybody know anything about this?

The name Lehr has been mentioned, but I thought he had something to do with glass.  Well, machines with the same name (Lehrs) are use to anneal glass (AFAICR).

when i visited the JCB factory some years ago they were friction welding their hydraulic rams together by holding the eye and spinning the rod at high speed then pushing the two together until they were one

Friction welding, and it's variant, friction stir welding have been around for quite some time.

I believe it's been touted as giving a more homogenous grain structure between the weld and parent metal, and having a smaller heat-affected zone.

I vist JCB on a regular basis as part of my job so I will ask next time (if I remember) and see what info I can collect.

Lots of axle casings are put together using friction welding. Not sure wether landy ones are one of them tho'

One the front loader, probably not (Us Fordies call it Timken or 'english' axle) but on the salisbury or rear-loaded quite possibly.  The salisbury axle for Escort I/II and Cortina I-V were friction welded.  It wasn't new then, but what is.
Apparently the Japanese (please forgive me if I'm wrong) built ships using electric arc welding before the war.  They sank due to fracturing in the heat effected zone around the welds, which don't give as easily as rivets did.

Isn't friction welding what you get when the grease on the wheel bearing doesn't to its job anymore :cry:

You then spend all that time trying to get the racer of the stub
