Muaj cov txheej txheem vuam sib txawv rau cov kav dej tsis sib haum uas siv cov txheej txheem vuam sib txawv. Cov txheej txheem vuam ntawm seamless square raj yog tsuas yog txiav txim siab raws li cov khoom siv, qib, tshuaj muaj pes tsawg leeg, hom qauv vuam, thiab vuam kev ua tau zoo ntawm cov welded seamless square raj.
Ua ntej, nws yog ib qho tsim nyog los txiav txim siab txoj kev vuam:
Cov txheej txheem vuam rau cov kav dej tsis sib haum tuaj yeem muab faib ua cov vuam tiaj tiaj, hla lub taub hau, thiab ntsug vuam.
Cov vuam vuam yog muab faib ua txoj kev vuam sab laug thiab txoj cai vuam txoj kev.
Qhov zoo ntawm txoj kev vuam: Lub vuam seam muaj qhov sib sib zog nqus qhov tob, tso cai rau kev pom tseeb ntawm qhov vuam seam thiab txo qhov kev pheej hmoo ntawm vuam sib txawv.
Qhov tsis zoo ntawm txoj kev vuam sab laug yog lub pas dej molten tsis tuaj yeem pom.
Qhov kom zoo dua ntawm txoj cai vuam txoj kev yog tias nws tuaj yeem pom meej lub pas dej molten, uas pab txhawb kev tsim thiab tswj ntawm seamless square tube welds.
Qhov tsis zoo ntawm txoj kev vuam txoj cai yog qhov tob ntawm qhov vuam yog qhov ntiav thiab nws yooj yim rau vuam sib txawv.
Vertical welding yog muab faib ua downward welding thiab upward welding.
Pav ca vuam yog haum rau ntau yam tam sim no welding, thaum nyiaj siv ua haujlwm thiab ntsug vuam tsuas yog tsim rau cov vuam tam sim no. Qhov ntev ntawm cov hlua hlau txuas los ntawm cov khoom siv hluav taws xob yog 10-15 npaug ntawm txoj kab uas hla ntawm cov hlau, thiab lub vuam lub kaum sab xis yog 45 degrees.
Tom qab txiav txim siab txoj kev vuam rau cov kav dej tsis sib haum, cov txheej txheem vuam txheej txheem yog tsim. Cov hom vuam txheej txheem tsis sib txawv, xws li phau ntawv arc vuam, uas feem ntau suav nrog: qauv electrode (los yog hom), txoj kab uas hla, tam sim no, qhov hluav taws xob, vuam fais fab hom, txoj kev sib txuas polarity, vuam txheej tooj, tus lej ntawm kev hla, kev tshuaj xyuas , lwm.
