TWI Industrial Member Report Summary 73/1978
By D N Shackleton
Background
Crack opening displacement and Charpy impact tests have been used to examine the toughness of electroslag welds in C-Mn and low alloy steels. The results obtained have indicated that acceptable values of toughness could be achieved in electroslag weldments in the as-welded and stress relieved conditions provided care is taken in the selection of steels and welding consumables. Variations in toughness have been encountered between nominally similar welds and these have been attributed to changes in the heats and batches of steel plates and welding consumables and to small differences in the welding conditions used.
