Abstract
In order to investigate the effect of different welding parameters on the welding width and depth,the mathematical and finite element model of plastic transmission welding were proposed,and the welding temperature distribution was calculated by means of ANSYS,and the welding width and depth for different parameters was predicted.The results show that the welding depth increases with increasing of the laser energy absorbed by polymethyl methacrylate (PMMA) in a unit area and unit time,the welding width is affected by the laser diameter and the laser energy absorbed by PMMA in a unit area and unit time,and the welding depth increases firstly and then decreases with the laser diameter increasing.
