• Evaluation of the Susceptivility of the Weld Solidification Cracking by Threshold Strain Method (Report 1)

抄録

A new method was proposed to estimate a susceptivility of weld metal to solidification cracking and various advantages in this method were made clear in this investigation. The results obtained are as follows; (1) The minimum strain to form solidification cracking is obtained by using this method.<BR>(2) The minimum strain was termed "TSSC (Threshold Strain for Solidification Cracking) value", and TSSC value is obtained by a following equation after performing a Trans-Varestraint Test. TSSC=ε₁ sin² θ, where ε₁ is augmented strain and θ is the angle between the welding direction and the normal to the solidiocation crack. (3) The following raltion exists between TSSC and CST value under the heat input per unit thickness of 19 kJ/cm² and the welding speed of 20 cm/min. TSSC=0.0807 (ln(CST))²+0.888 In (CST)+2.51 (4) The effect of the welding conditions on the susceptivility of the weld solidification cracking are able to be examined by using this method.
