1. Kev xaiv ntawm vuam pas nrig:
1.1 Cov yeeb nkab hauv paus vuam siv argon arc electrode nrog lub cheeb ntawm 3.2 hli. Filling, npog vuam siv hlws ris 507 electrode, txoj kab uas hla ntawm electrode yog 3.2 ~ 4.0mm.
1.2 Lub vuam pas nrig yuav tsum muaj lub Hoobkas tshwj xeeb, thiab txheej txheej ntawm vuam pas nrig yuav tsum tsis txhob poob thiab tsis muaj qhov pom tseeb tawg. Khaws raws li cov lus qhia ua ntej siv thiab kom qhuav thaum siv.
2. Kev npaj ua ntej vuam:
2.1 Qhuav lub electrode ua ntej welding, thiab siv cov cua kub preservation chim kom cov electrode tom qab ziab.
2.2 Ntxuav cov roj, xeb, slag, thiab lwm yam hauv 20mm ntawm cov yeeb nkab kawg ua ntej vuam cov yeeb nkab.
2.3 Qhov chaw vuam yog nqa tawm tom qab cov pab pawg sib koom ua ke, thiab tus naj npawb ntawm qhov chaw vuam yog 6-8, uas yog sib npaug ntawm cov yeeb nkab. Vuam tuaj yeem ua tau tom qab kev sib dhos ntawm lub nozzles tiav.
3. Cov yeeb nkab vuam:
3.1 Lub raj xa dej tau txais ntau txheej txheej vuam, thiab cov txheej txheem yog txiav txim siab raws li qhov tuab ntawm cov yeeb nkab phab ntsa. Vuam tsis muaj hauv paus weld, muab tub lim weld thiab cap weld.
