Paper Title:
Research of Laser Welding for Hot Rolling Strip Steel
  Abstract

Focused on the question of laser welding break of hot rolling strip steel JZZ, The causings of defect of laser welding were studied experimentally with the Trumph TLF12000 fast-flow CO2 laser,. and the methods of avoiding the defect were porposed. The results showed that owing to the steel plate was thicker and big welding velocity, resulted in large depth/breadth ratio and high cooling velocity , the solidification crack occurred during welding process. When the method of laser welding with filling metal was used,the welding defect was avoided , the better performance index of weld as good as that of base metal is available.
