Iinkqubo zokuwelda umbhobho ovuthelweyo zinokwahlulwa zibe zi-spiral welded kunye ne-straight seam welding, kunye nenkqubo ye-galvanized spiral welding yinani elibanzi lezicelo, kodwa kunzima ngakumbi.

Indlela yokuwelda umbhobho ovunguzayo oyigalvanized yeyokuqala ukuphuma kwinxalenye yesiphelo se-electrode emalunga ne-5 ~ 7mm, ngaphandle kokushiya itekhnoloji ebuthuntu yolawulo oluphakathi ukuthomalalisa ishishini kufuneka linike ingqwalaselo yokuphatha ngokunzulu imilinganiselo yegroove kunye nomaleko we-zinc kufutshane-efakwe.

Ukungena, i-undercut tendency iya kuba yincinci kakhulu, Ukuba i-front and behind iteknoloji yokuthutha uhambo olujikelezayo isetyenzisiweyo, ngokubanzi i-1.5 ~ 2.5mm;ukunciphisa i-zinc weld ukungena, kugxininise ekudlaleni ukuhla koshishino lwe-groove, njengokusetyenziswa kwe-slag ye-welding emfutshane efana ne-J427, ukushiya icandelo elithile lesithuba kulindeleke ukuba linciphise kakhulu i-zinc engamanzi ihlale kwi-weld, xa i-welding fillet welds, awukwazi ukufumana iziphene zomgangatho welding.

Izinto ezilungileyo zokuwelda i-galvanized spriral: ukuchaneka kwe-welding ayinakuthelekiswa ne-welding ye-welding ethe tye, imibhobho emikhulu edayamitha okanye eminye imibhobho ekhethekileyo isetyenziselwa umbhobho odibeneyo we-spiral, ngenxa yokuba ubuninzi be-welding ye-spiral inkulu, i-welding up ibhetyebhetye kakhulu, idityaniswe kunye. inokwenza utshintsho oluninzi.Kodwa ukuwelda komthungo okuthe tye kunokudibanisa umgca omnye kuphela, igophe le-welding ethe tye ayikwazanga ukudlala ngokupheleleyo, ngoko ke, Ukusetyenziswa kwe-spiral welded lolona khetho lungcono.
