Paper Title:
Weldability of Ca Microalloyed HSLA Steel
  Abstract

The welding cold cracking tendencies of Ca microalloyed HSLA steel was evaluated using crack sensitivity index Pcm, oblique Y-groove cracking test and the hardness of simulation CGHAZ(coarse grain heat affected zone) in this paper. The organizational structure and mechanical properties of simulation CGHAZ at different t8/5 was analysised in this paper two. The results show that:steel welding cold crack is less sensitive; the CaO pinning austenite grain boundaries effectively, fining the grain size of CGHAZ, increasing the amount of IFA, and improving the toughness of CGHAZ.The weldability of Ca microalloyed HSLA steel is good.
