Abstract

The present study examined the characteristics of high speed welding thin metal sheet using single mode fiber laser of averaged maximum output power 300 W. Due to the fiber laser that has a good quality of beam can make a very small focusing beam size, thin metal sheet welding and high speed key hole welding can be peformed by high power density.
