高强度低合会钢焊接时产生的层状撕裂,对重要的结构件是十分有害的。在角接接头,T型接头,开坡口的、不开坡口的,或是它们的组合焊缝的热影响区会产生很大的焊接应力。这种产生于板厚方向上的高拉伸应力的大小,取决于焊缝的尺寸、焊接方法和构件接头处的拘束应力。 Layered tearing during high-strength low-profile steel welding is very detrimental to important structural parts. In the corner joints, T-joints, grooved, non-grooved, or their combined weld heat-affected zone will have a great welding stress. The magnitude of this high tensile stress in the direction of the sheet thickness depends on the size of the weld, the method of welding and the restraining stresses at the joint of the component.
