The lower critical stress of weld metal of 60, 70, 80, 90 and 100kg/mm^2 steels in strength levels was measured by the LB TRC test, previously reported, with SMA and GTA argon and argon-hydrogen mixed shielding gases welding. Moreover the susceptibility of cold cracking was evaluated by "Embrittlement Index", I, etc. Consequently, it was seen that the lower critical stress of weld metal decreases rapidly with an increase in diffusible hydrogen content in the range 0 to 3ml/100g and the weld metal of 100kg/mm^2 class steel in strength level was most susceptible to cold cracking.
