Abstract

This paper put forward a mathematic model of point-line combined heat conduction,shows the computer solving procedure and plotting to describe the laser deep penetration welding profile and HAZ isotherms.Using the model to analyze the various laser bead welding shapes, it is proved that the calculation results are well coin-cide with actual welding, So,the model can be used to solve the practical welding problem.
- laser deep penetration welding,
- heat transfer model
