摘要：The invention relates to a method for forming a welded joint between abuttingpieces of steel. The welded joint is produced by first forming a strength weld and thendepositing additional weld metal on the toe of the strength weld to form a toughnessweld. The fusion interface of the toughness weld forms a minimum angle with thedirection of the maximum tensile load across the welded joint. The toughness weld toe isseparated from the heat-affected zone of the strength weld to effectively preventpropagation of a crack initiated at the toughness weld toe into the heat-affected zone ofthe strength weld. The welded joint so produced is substantially resistant to failure bybrittle fracture.
