Spiral weld seam e na le mefuta e 'maloa e latelang:

1. Spiral hlobolisa qetellong weld: tšepe hlooho hore spiral weld holim'a tšepe kapa tšepe weld hlooho le mohatla;
2. Peli spiral butt weld: spiral cut ke ho hokahanya tse peli hammoho ho etsa annular weld;
3. Spiral tack welding: e sebelisoa pele ho tjheseletsa ho qetela.Bakeng sa likarolo tse tsitsitseng tsa weld.

Tlhahlobo ea Parametric ea seam welding
⑴ bophara ba weld bo bolela mateano a sebaka sa weld le tšepe e bitsoang weld toe.The single-pass weld cross-section, sebaka se pakeng tsa tse peli se bitsoa seam weld toe bophara.

⑵ ka nģ'ane ho holim'a matlafatso ea weld e bolela ho hokahanngoa bophahamong ba karolo ea monoana oa weld ea tšepe e bitsoang reinforcement.Ke etsa cross-karolo ea weld seam ea keketseho e phahameng ea ho jara bokgoni e eketseha, 'me ka eketsa kutloisiso ea ray radiography, empa e tla etsa hore weld monoana khatello ea kelello mahloriso.Hangata e hloka ho feta holimo ho se be ka tlase ho lisebelisoa tsa motheo, ho eketsa botenya ba eona le ho eketsa bophahamo ba lisebelisoa tsa 'mè, empa boholo ha boa lokela ho feta 3mm.

⑶ ho kenella ka hare ho lenonyello le cheselitsoeng, thepa ea motheo e bitsoa botebo ba ho kenella ha ho qhibilihisoa.Boleng bo itseng ba ho etsa bonnete ba hore ho kenella ho kopantseng weld le matla a tšepe a motheo.Ha thepa ea tšepe ea filler (thupa kapa terata) e sa fetohe, botebo ba ho kenella bo lekanya boholo ba k'hemistri ea weld e feteletseng.Mekhoa e fapaneng ea ho tjheseletsa e hloka boleng bo fapaneng ba ho kenella, ho etsa mohlala, ho tjheseletsa, ho pota-pota lera e le ho boloka ho thatafala le ho fokotsa ho hlapolla ha tšepe ea motheo ea weld, sebakeng sa ho netefatsa ho kenella ho lokela ho hloka botebo bo fokolang ba ho kenella.
