Process Analysis of Laser Welding Method with Polybutyleneterephthalate (PBT)
The present study introduces the use of absorption energy as a parameter in thermal diffusion for explaining and predicting experimental results in laser welding. The developed parameter was utilized for the welding experiments of polybutyleneterephthalate (PBT). It was found that maximum welding strength values lie almost in the same range of absorption energy values for all cap thickness and scan velocity values considered in this work. One may then conclude that the absorption energy in thermal diffusion is an essential parameter for predicting experimental results in laser welding.
