Experimental investigation and numerical modeling of plasma and laser microwelding processes

Abstract

In the growing technological field like micro electro mechanical systems MEMS and biomedical devices the microwelding has potential application as encapsulation of miniature components This thesis work is primarily motivated to develop plasma microwelding system for butt joining of different materials At first the major efforts are put forward to experimentally investigate the thermo mechanical and microstructural behavior for joining of titanium alloy stainless steel and low carbon steel
