Ekuqaleni, umshini we-laser welded finning ikakhulukazi wawuhlanganisa ishubhu lensimbi engagqwali elinamaphiko ensimbi engagqwali.Ngesikhathi sokuthuthukiswa kobuchwepheshe, ishubhu le-carbon steel eline-carbon steel fin liba ne-encomical, njengesisindo esiphansi namandla okudlulisa ukushisa aphezulu.Kwezinye izikhathi, ishubhu ye-laser eshiselwe i-carbon steel finned ingathatha indawo yamashubhu afakwe imvamisa ephezulu ashiselwe.
Umshini wokushisela we-laser othomathikhi we-spiral fin welding usebenzisa i-laser enamandla kakhulu ukushisela amashubhu anezici.Okokufaka kokushisa kwe-laser kuncane, umphumela unembile, futhi i-fin ngemva kokushisela inomthelela omncane ekushiseni kwe-laser.Imishini yonke iyi-othomathikhi eshiselwe ishubhu eshiselwe ngokugcwele, enamaphiko alimele ngakolunye uhlangothi kanye namaphiko ashiselwe nge-laser ngakolunye uhlangothi.Phakathi nayo yonke inqubo yokukhiqiza, opharetha udinga kuphela ukulayisha impahla ekuqaleni kwe-welding futhi ayikhiphe ngemva kokuqedwa kokufakwa kwe-welding.Ekusebenzeni okuvamile, umugqa wensimbi ulimala ngokuzenzakalelayo epayipini lensimbi, futhi ukuvuthwa kweshidi okuzenzakalelayo, i-laser automatic welding, kanye nezinga eliphezulu lokuzenzekelayo kufinyelelwa.

Amashubhu ane-spiral finned ahlala ekhiqizwa yi-high frequency welding, brazing noma inlaying.Le nqubo yokukhiqiza yendabuko yenza ukudluliswa kokushisa nokusebenza kahle kokupholisa kwe-tube enefine kungabi phezulu kakhulu, futhi kuzoba nokushisela okubuthakathaka kanye nokukhishwa kwe-soldering.Okubaluleke nakakhulu, ngemva kokushisela i-high-frequency welding, izinga lokushisa liphezulu kakhulu futhi umphumela wokushisa mkhulu kakhulu, okwenza kalula ishubhu elifakwe emanzini ligle, elikhawulela indawo yokusetshenziswa kweshubhu elifakwe.Endaweni egqwalayo, ishubhu elifakwe insimbi lizogqwala ngemva kwesikhathi esifushane lisetshenziswa.Ngisho noma ishubhu lensimbi engagqwali elicijile lishiselwe imvamisa ephezulu, alikwazi ukuhlangabezana nezidingo, ikakhulukazi ngenxa yokuthi amaphiko adonsa ukushisa okukhulu futhi izinga lokushisa liphezulu kakhulu, okuthinta ukuhlelwa kwe-athomu yensimbi engagqwali.Insimbi engenasici, kulula ukugqwala futhi inciphisa ukumelana nokugqwala.I-laser welding ayidingi ukucabangela izinkinga ezinjalo nhlobo.Ukushisela nge-laser kwenziwa ngokuphazima kweso, futhi amaphiko ashiselwe awanamthelela ekubuyiseleni ukushisa.Ukumelana nokugqwala kwensimbi engagqwali akunciphi, ngakho-ke ezindaweni ezine-asidi eqinile ne-alkali, amashubhu ane-laser welding finned kufanele abe nekhono.
