Welcome to the New Year celebration events in the Leisure Area. The more you participate, the more you share – it’s a time for joyful communication and fun. HaiChuan’s 2016 year-end work summary sharing event – http://bbs.hcbbs.com/thread-1663239-1-1.html (Source: HaiChuan Network). Pick up your phone and contribute recipes for Spring Festival dishes from various places in the Food section! http://bbs.hcbbs.com/thread-1666032-1-1.html (Source: Haichuan Net) [Haichuan·The Road Home] Sharing Event http://bbs.hcbbs.com/thread-1655900-1-1.html (Source: Haichuan Net) ---------------------------------------------------------------------------------------- Friction welding is a method in which heat generated by the friction between the end surfaces of the workpieces is used to bring those surfaces to a plastic state, after which forging is carried out to complete the welding process ； Working principle of friction welding: During friction welding, the workpieces come into mechanical contact under pressure; at the same time, rotation or relative movement between the workpieces generates frictional heat, causing plastic displacement of the atoms on the friction surfaces. Under the combined effect of pressure and frictional heat, the atoms near the friction surface of the welded parts are activated (atomic diffusion increases, and the surface oxide layer and contaminants are pushed out), thereby migrating to form a bond. ...The common friction welding method involves welding column-shaped parts to other column-shaped parts in this manner
I saw on the internet a video of friction welding a long-shaped workpiece, which is quite unusual; I’d like to share it with everyone
A video screenshot of a workpiece being processed
I once watched a video about the welding of external threaded casings to drill pipes and main pipes; it showed a complete set of equipment, including the subsequent machining process to flatten the outer surfaces.
Conventional rings can be friction welded to other rings; for example, the universal joint heads in cars. I’ve seen the serpentine tubes in the water cooling walls of boilers being welded using friction welding
I always feel that friction welding isn’t durable; I don’t know why
Should flux also be added to this weld?
