Effects of hydrogen upon the properties of thermo mechanical controlled process (TMCP) steel

Research into the effects of hydrogen on the mechanical properties of the material is wide- ranging and time-consuming, since there is no single way of predicting cold cracking that would be applicable to all steel grades. Some research on the action of hydrogen in the weld area has focused on the effects of filler materials, welding parameters, the welding environment and welding process upon the hydrogen content of the weld metal and final effect of the hydrogen content upon the properties of the material.
