焊接坡口必须符合产品设计的有关规范标准;还要考虑母材的焊接性,结构的刚性、焊接应力、诸焊接方法的特点及其熔深;对于奥氏体耐酸钢的焊接,要注意焊接坡口的型式和尺寸对抗窝蚀性能的影响。本文针对实际生产中焊接坡口型式与尺寸存在的情况,从设计焊接坡口的依据,无钝边V型坡口和有钝边Y型坡口,手工焊V型或Y型的坡口角度值等方面进行探讨研究,为焊接坡口的合理设计提供了有用的参考。
Welding bevel must meet the relevant specifications of product design; also consider the base metal welding, structural rigidity, welding stress, the characteristics of welding methods and penetration; for austenitic acid-resistant steel welding, pay attention to welding Effect of groove type and size on erosion resistance. In this paper, the actual production of welding groove type and size of the situation, from the design of welding groove basis, no blunt edge V-groove and blunt Y-groove, hand-welded V-type or Y-type groove angle Value and other aspects of the study, the rational design of the weld groove provides a useful reference.
