cygnusx1 Posted January 15, 2008 Share Posted January 15, 2008 Friction Stir Welding. http://www.msm.cam.ac.uk/phase-trans/2003/FSW/aaa.html Basically, a high speed/pressure tool melts the parts together along a seam using no filler materials. Mainly good for aluminum. Quote Link to comment Share on other sites More sharing options...

HoustonZ Posted January 15, 2008 Share Posted January 15, 2008 I've done this before in the milling machine, on accident Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 15, 2008 Share Posted January 15, 2008 My wife did that to a car when the oil change place didn't put the oil cap back on the engine.... Quote Link to comment Share on other sites More sharing options...
johnc Posted January 15, 2008 Share Posted January 15, 2008 Its been around for about 20+ years. Its only become practical for non-aerospace use due to cost reductions. Its can effectively weld ferrous and non ferrous metals. Quote Link to comment Share on other sites More sharing options...

Pop N Wood Posted January 16, 2008 Share Posted January 16, 2008 Z car stub axles are friction welded together. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted January 16, 2008 Author Share Posted January 16, 2008 "New Welding Method" I stand corrected. "New-to-me-Welding Method" Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted January 16, 2008 Share Posted January 16, 2008 I'm a member of the AWS (american welding society) and get their welding journal every month. Very cool stuff in the magazines. It's like $25 to sign up if your a student and worth it! Quote Link to comment Share on other sites More sharing options...
jerryb Posted January 16, 2008 Share Posted January 16, 2008 Ya it has been around for a long time....I believe another "new" way of doing this is by melting the two materials with an electron beam. Quote Link to comment Share on other sites More sharing options...
TONY C Posted January 16, 2008 Share Posted January 16, 2008 Not exactly going to find a welder like that in your garage tho. Or your neighbors. Quote Link to comment Share on other sites More sharing options...
johnc Posted January 16, 2008 Share Posted January 16, 2008 Actually, there's a difference between Friction welding and Friction Stir welding. Friction welding, spinning two parts real fast and mashing them togehter, has been around for 70 years or more. Friction Stir welding is different in that a high speed bit is mashed into the two parts and dragged along the weld seam. Quote Link to comment Share on other sites More sharing options...
