Interim Report on Submerged Arc Weld Toughness Distribution

 

Interim Progress Report on Toughness Distributions in a Submerged Arc Weld

TWI Industrial Member Report Summary 110/1980

By G O Johnston

Background

Crack opening displacement tests have been carried out on submerged arc weld metal with the same base plate (BS 4360 Grade 50D steel) as a previous plain plate programme of tests. This should enable a statistical comparison of data to be carried out as part of future work. The results are reported in an analogous manner to the first set on plain plate and best fitting normal, lognormal and Weibull distributions were found. The results varied according to the testing conditions.
