Cold crackzvikonzero: munhu achaiswa pasi pewelding kana hombe tensile simba inogona kubvarurwa nyore mukuita kutonhodza welding zvinhu kuoma;welding kutonhora mwero wakanonoka kutiza yakasara yehydrogen muweld, atomu yehydrogen yakasungirirwa kune mamorekuru ehydrogen kune gasi mamiriro emukati mapores akanaka esimbi uye kukonzera kudzvinyirira kwakawanda, zvekuti simbi inotonhora inoputika inotsemuka. kudzvinyirirwa kwakawanda;welding stress uye tensile stress analysis ine tarisiro pane hydrogen embrittlement uye kuoma kunoitika panguva imwe chete nyore kuumba kana kuchitonhora kutsemuka.

Matanho ekudzivirira: preheat uye kunonoka kutonhora mushure mekuputika, kupisa-kukanganisa zone austenite decomposition inogona kuva yakakwana tembiricha renji, kudzivirira kuomarara matishu, nepo ichideredza basa rekushushikana muwelding;panguva yakakodzera hypothermia mushure mekugadzira annealing, dehydroepiandrosterone kurapwa, kubvisa kushushikana kunogadzirwa panguva yewelding, uye kupararira kwehydrogen panguva yakakodzera kuenda kunze;kusarudzwa kweyakaderera hydrogen type electrode uye alkaline flux kana austenitic Stainless steel welding wire, nezvimwewo, zvinoshandiswa zvinoda kuomeswa uye zvakasimba kuchenesa-up groove;kudzivirira uye kusimbisa welding yakakandwa pamusoro pekuchenesa, kudzivirira kupindira kwehydrogen;sarudza zvinonzwisisika welding zvirevo, uchishandisa zvine musoro kuungana uye kutevedzana kwewelding.
