Yog, nickel tuaj yeem welded rau hlau los ntawm ntau yam txheej txheem vuam. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov sib txawv ntawm cov khoom ntawm cov npib tsib xee thiab cov hlau thiab xaiv txoj kev vuam tsim nyog kom ua tiav qhov muaj zog thiab txhim khu kev qha. Qhov kev xaiv ntawm vuam txoj kev yuav nyob ntawm seb yam xws li cov qib tshwj xeeb ntawm npib tsib xee thiab hlau, daim ntawv thov, thiab cov khoom xav tau ntawm kev sib koom ua ke.
Cov txheej txheem welding feem ntau rau kev koom nrog nickel rau hlau muaj xws li:
Shielded Hlau Arc Vuam (SMAW los yog Vuam Vuam):
SMAW suav nrog kev siv lub tshuab hluav taws xob-coated los tsim hluav taws xob arc nruab nrab ntawm cov electrode thiab cov ntaub ntawv hauv paus. Nws yog txheej txheem ntau yam tsim nyog rau vuam nickel rau hlau, tab sis nws yuav tsum tau ceev faj xaiv cov ntaub ntawv muab tub lim thiab preheat tej yam kev mob.
Gas Tungsten Arc Vuam (GTAW lossis TIG Vuam):
TIG vuam siv lub tungsten electrode los tsim ib qho arc, thiab cov khoom sib cais tuaj yeem muab ntxiv yog tias tsim nyog. TIG welding feem ntau yog siv rau vuam npib tsib xee rau hlau vim nws qhov tseeb thiab muaj peev xwm tswj tau cov cua sov.
Gas Metal Arc Vuam (GMAW or MIG/MAG Vuam):
MIG/MAG welding yog siv cov khoom siv hluav taws xob siv hluav taws xob thiab hluav taws xob tiv thaiv. Txoj kev no yog tsim rau vuam npib tsib xee rau hlau, thiab nws tso cai rau kev vuam nrawm dua piv rau lwm cov txheej txheem.
Flux-Cored Arc Vuam (FCAW):
FCAW yog txheej txheem uas siv cov tubular xaim uas muaj cov dej ntws los tiv thaiv lub pas dej ua ke. Nws tuaj yeem siv rau vuam npib tsib xee rau hlau, muab cov nqi tso nyiaj siab thiab kev nkag mus zoo.
Submerged Arc Welding (SAW):
SAW feem ntau yog siv rau vuam thicker seem ntawm nickel rau hlau. Nws suav nrog cov khoom siv hluav taws xob tsis tu ncua thiab cov khoom siv hluav taws xob uas npog lub pas dej ua ke. SAW yog lub npe hu rau kev vuam ceev thiab kev sib sib zog nqus.
Explosion Vuam:
Thaum tsis yog txheej txheem vuam ib txwm, kev tawg vuam yog cov txheej txheem siv los khi cov hlau tsis sib xws, suav nrog npib tsib xee thiab hlau. Txoj kev no suav nrog kev siv lub zog tawg los tsim kev sib txuas ntawm cov khoom siv hlau.
Thaum welding npib tsib xee rau hlau, nws yog ib qho tseem ceeb uas yuav tau xav txog tej yam xws li kev sib koom tsim, preheating, tom qab vuam thaum tshav kub kub kho (PWHT), thiab xaiv cov khoom muab tub lim tsim nyog. Tsis tas li ntawd, cov txheej txheem vuam thiab cov txheej txheem tsim nyog yuav tsum tau ua raws li kom ntseeg tau tias muaj kev sib koom ua ke muaj zog thiab ruaj khov. Kev sab laj nrog cov kws tshaj lij vuam lossis cov kws ua haujlwm paub txog kev sib txawv ntawm cov hlau vuam yog pom zoo rau cov ntawv thov tshwj xeeb.
