对焊接材料纳入修订的标准《压力容器——分析设计》材料篇的探讨
|
摘要
焊接材料属于压力容器用材料最薄弱的环节,它影响着压力容器质量和运行周期。但是,焊接材料的质量和选用尚未得到应有的重视,未纳入GB/T 150和JB 4732—95等相关标准的材料篇。近年来,经行业同仁的努力,在新修订的GB/T×××××—201×《压力容器——分析设计》标准中,首次将焊接材料作为重点纳入材料篇。根据分析设计的特点,对本标准中规定的焊接材料熔敷金属试验项目及合格指标进行探讨,并提出选用高端焊接材料时应注意的事项,以供同行借鉴。
Welding material is the weakest link of the materials for pressure vessels,which affects its quality and operation cycle.However,the quality and selection of welding materials have not received the due attention in China,and they have not been admitted in material section of related Chinese standards such as GB/T 150 and the original JB 4732—95. In recent years,through the efforts of industrial colleagues,welding materials have been included as a focus for the first time in the latest revised standard GB/T × × × × × —201 ×"Pressure Vessel—Design by Analysis". According to the characteristics of the design by analysis,the author explored the test items and qualification indexes of the deposit metals of welding materials specified in this standard,and put forward some precautions when selecting high-end welding materials for colleagues' reference.
