| titleOfInvention | A kind of technique reducing X80 pipe line steel Cold Cracking Susceptibility |
| abstract | The present invention relates to pipeline welding technical field, particularly relate to a kind of technique reducing X80 pipe line steel Cold Cracking Susceptibility, comprise preheating, welding and post weld heat treatment step.Adopt higher preheat temperature to slow down the cooling velocity of postwelding, be conducive to the effusion of diffusible hydrogen in weld metal, also reduce the degree of hardening of weld dimensions simultaneously, improve the crack resistance of welding point.Postwelding is heat-treated immediately, and Slow cooling after first high-temperature heating is also incubated, and to eliminate postwelding residual stress, impels the diffusion of residual hydrogen excessive.The cold crack because constraint stress and hardened structure cause can be reduced like this. |
