摘要
为了研究堆焊单一E309L熔敷金属的焊接工艺和接头性能,采用埋弧焊(SAW)在14Cr1MoR基体上堆焊一层EQ309L焊带,焊接过程中严格控制焊接热输入和采用有效的消应力退火热处理制度,保证堆焊层顺利通过无损检测以及弯曲、化学、铁素体数量、硬度试验、金相组织分析和晶间腐蚀等理化性能检测。结果表明,采用埋弧焊(SAW)堆焊单层EQ309L时堆焊层的塑韧性能满足要求,晶间腐蚀试验合格,可以用在压力容器的表面堆焊中。
In order to study the welding process and mechanical properties of surfacing welding E309L, surfacing one layer EQ309L strip electrode on 14Crl MoR base metal using the submerged arc welding（SAW） , strictly eontrol tire welding heat input and adopt effective post weld heat treatment time in tire wehling proc：ess. The above measures ensure that the results of nondestructive examination, bending, chemical con,position tests, harduess tests, metallographic examination and intergranular corrosion test are qualified. The test results show that tire plasticity and ductility of surfacing one layer EQ309L strip electrode using the SAW meet the requirements, the results of intergrauular con＇osion test are qualified, the welding proceess could be applied in tire surfacing welding of pressure vessel.
