hydrogen-welding

基本解释

Because of the fast cooling of flowing medium, the hydrogen cracking occurs easily under in-service welding.
在役焊接过程中，管内流动介质的快速冷却，易使接头出现氢致裂纹。
The microcrack is developed quickly into nucleus in the second stage by hydrogen-assisted cracking in welding seam.
第二阶段是氢助裂纹作用使微裂纹迅追扩展而成为白点核。
Evaluation of welding process and hydrogen -resistant peeling test of the clad plate shows that this product possesses excellent, reliable manufacturing and operation properties.
复合钢板经焊接工艺评定和抗氢剥离试验证明，该产品具有优良可靠的制造和使用性能。
