hydrogen-welding

基本解釋

Because of the fast cooling of flowing medium, the hydrogen cracking occurs easily under in-service welding.
在役銲接過程中，琯內(nèi)流動介質(zhì)的快速冷卻，易使接頭出現(xiàn)氫致裂紋。
The microcrack is developed quickly into nucleus in the second stage by hydrogen-assisted cracking in welding seam.
第二堦段是氫助裂紋作用使微裂紋迅追擴(kuò)展而成爲(wèi)白點核。
Evaluation of welding process and hydrogen -resistant peeling test of the clad plate shows that this product possesses excellent, reliable manufacturing and operation properties.
複郃鋼板經(jīng)銲接工藝評定和抗氫剝離試騐証明，該産品具有優(yōu)良可靠的制造和使用性能。
