【Abstract】 The new model suited to various laser processings is established by analysing the thermal conduction Model. This model is then used to a computer simulation calculation of laser pro-cessings (weldings). The results show that the theoretical calculation values are approximately identical to the practical test ones. Therefore, it is proved that the model is rights.更多还原
