结果显示，一定的母材厚度和焊后热处理条件，使熔合线附近氢浓度峰值提高，从而使氢剥离倾向增大。
The results show that certain thickness of the base metal and the regime of heat treatment will increase the peak hydrogen concentration and promote the tendency of disbonding.
当氢含量大于0.2%(质量分数)时，由于此时氢元素的固溶强化起主导作用，因此随氢含量的增加，峰值应力随之增加。
When hydrogen content was bigger than 0.2%, the peak stress increased with the increase of hydrogen content, because hydrogen played a main role of strengthening.
