KEY DRIVERS AND PRIORITIES OF CONSUMER DECISIONS FOR REFURBISHED ELECTRONICS: A MIX-METHOD APPROACH


Optimization of process parameters of rotary friction welding of low alloy steel tubes using response surface methodology

Rotary Friction Welding (RFW) is a solid-state welding process that is becoming increasingly popular due to advantages such as low weld heat input, high production efficiency, ease of manufacture, and environmental friendliness.Rotary friction welding can weld materials that are difficult to fuse using fusion welding techniques.The main objective o
