Spiral weld seam ili ndi mitundu ingapo:

1. Spiral Mzere mapeto kuwotcherera: chitsulo mutu kuti mozungulira kuwotcherera pa chitsulo kapena zitsulo weld mutu ndi mchira;
2. Kuwotcherera kozungulira kozungulira: Kudula kozungulira ndikulumikiza ziwirizo kuti zikhale zowotcherera;
3. Spiral tack kuwotcherera: kuti ntchito pamaso kuwotcherera komaliza.Kwa m'mphepete mwa ma weld okhazikika.

Kusanthula kwa parametric kwa msoko wowotcherera
⑴ weld m'lifupi amatanthauza mphambano ya weld pamwamba ndi maziko chitsulo chotchedwa weld toe.The single-pass weld cross-gawo, mtunda pakati pa awiriwa amatchedwa msoko weld chala m'lifupi.

⑵ kupitirira pamwamba pa chowonjezera chowotcherera chimatanthawuza kugwirizana komwe kuli pamtunda wa gawo la chala cha weld cha chitsulo chowotcherera kumatchedwa kulimbikitsa.Ine kupanga mtanda gawo la weld msoko wa kuwonjezeka mkulu kunyamula mphamvu chiwonjezeke, ndipo akhoza kuonjezera tilinazo ray radiography, koma adzapanga weld chala nkhawa ndende.Kawirikawiri amafuna zambiri kuposa mkulu osati zochepa kuposa zinthu m'munsi, kuwonjezera makulidwe ake ndi kuonjezera kutalika kwa zinthu mayi, koma pazipita sayenera upambana 3mm.

⑶ malowedwe olowa mtanda wa olowa welded, zinthu m'munsi amatchedwa kuya kwa malowedwe osungunuka.Ena mtengo kuonetsetsa kuti ophatikizana malowedwe weld ndi m'munsi zitsulo mphamvu.Pamene zitsulo zazitsulo (ndodo kapena waya) zimakhala zokhazikika, kuya kwake kumatsimikizira kukula kwa chemistry yowotcherera kwambiri.Osiyana kuwotcherera njira amafuna osiyana malowedwe mtengo, mwachitsanzo kuwotcherera, pamwamba wosanjikiza kuti akhalebe kuuma ndi kuchepetsa dilution wa zitsulo m'munsi wa weld, m'malo kuonetsetsa malowedwe ayenera kumafuna kuya ang'onoang'ono malowedwe.
