Abstract

Nowadays, laser welding is a process that been used in the industry. This process is one of the advance technologies that really need in the industry because of the short time processing and non-contact tool with the workpiece. But, the disadvantage of this process is required high cost in order to setup a new laser welding machine. Hybridizing is a solution whereby laser cutting machine is used in order to do the laser welding process. Hybridization is the process by which two different sets of process are bred together in one machine. This study is to investigate the potential of hybridizing laser welding onto CO2 laser cutting machine. From the hybridizing process, it provides the economical solution in material processing. Investigation is made in order to find the optimized process parameters that are laser power, travel speed, frequency. Then, Design of Experiment (D.O.E) analysis is structured and result is obtained from the experimental process. The results give an excellent weldability in joining mild steel ss400 with the thickness of 2.6mm.
