Txias tawgyog vim li cas: tus neeg yuav tsum tau welding thaum lub zog tensile loj yuav torn tau yooj yim nyob rau hauv tus txheej txheem ntawm txias vuam cov ntaub ntawv hardenability; welding txias npaum li cas lig dhau lawm kom khiav tawm cov seem hydrogen nyob rau hauv lub weld, ib tug hydrogen atom bonded rau ib hydrogen molecules mus rau ib tug gaseous lub xeev mus rau hauv lub zoo pores ntawm cov hlau thiab ua rau lub siab ntau, yog li ntawd lub zos txias-tsim hlau tawg. siab ntau; welding kev nyuaj siab thiab tensile kev nyuaj siab tsom xam nrog rau kev tsom mus rau hydrogen embrittlement thiab hardening tshwm sim ib txhij yooj yim tsim thaum txias cracking.

Kev tiv thaiv kev tiv thaiv: preheat thiab txias txias tom qab vuam, tshav kub-cuam tshuam cheeb tsam austenite decomposition tuaj yeem yog qhov kub txaus, kom tsis txhob muaj cov tawv nqaij tawv, thaum txo lub luag haujlwm ntawm kev ntxhov siab hauv vuam; raws sij hawm hypothermia tom qab vuam annealing, dehydroepiandrosterone kev kho mob, tshem tawm kev ntxhov siab generated thaum lub sij hawm vuam, thiab mus rau diffusion ntawm hydrogen raws sij hawm mus rau sab nraud; xaiv cov khoom siv hluav taws xob tsawg thiab cov alkaline flux lossis austenitic stainless hlau vuam hlau, thiab lwm yam., cov khoom siv yuav tsum tau ziab thiab nruj tu qhov zawj; tiv thaiv thiab ntxiv dag zog welded welded ntawm qhov chaw tu, kom tsis txhob muaj kev cuam tshuam ntawm hydrogen; xaiv qhov tsim nyog vuam specifications, siv tsim nyog los ua ke thiab vuam ib ntus.
