摘要
通过一系列高强钢熔敷金属扩散氢含量的试验,系统地研究了空气湿度和钢板初始温度对焊缝扩散氢含量的影响。结果表明,空气湿度和钢板初始温度对高强钢焊接接头中扩散氢含量有十分明显的影响,通过降低空气湿度和提高钢板的初始温度,是降低高强钢的焊接接头扩散氢含量的有效措施。
The effects of air humidity and initial temperature of steel plate on the content of hydrogen diffused in deposited metal of high strength steel were researched by experiment. The results indicate that the effects of air humidity of welding environment or initial temperature of the base material have great influences on the content of hydrogen diffusion. Decreasing air humidity and increasing the initial temperature can effectively reduce the content of hydrogen diffused in deposited metal of high strength steel.
