Thaum pib, laser welded finning tshuab feem ntau welded stainless hlau raj nrog stainless hlau fins.Thaum lub sij hawm tus txheej txheem technolgy tsim, carbon steel tube nrog carbon steel fin ua encomical, xws li qis luj thiab siab dua kub hloov tau.Qee lub sij hawm, Laser welded carbon steel finned tube tuaj yeem hloov lub siab zaus welded khoom finned leeg.
Laser tsis siv neeg vuam kauv fin vuam tshuab siv lub zog siab ceev laser rau vuam finned hlab.Lub laser cua sov input tsawg dua, cov nyhuv yog qhov tseeb, thiab cov fin tom qab vuam muaj qhov cuam tshuam me ntsis ntawm cov cua sov laser.Tag nrho cov cuab yeej yog tag nrho tsis siv neeg finned raj vuam, nrog fins qhov txhab ntawm ib sab thiab laser welded fins ntawm lwm sab.Thaum lub sij hawm tag nrho cov txheej txheem ntau lawm, tus neeg teb xov tooj tsuas yog yuav tsum thauj khoom thaum pib vuam thiab tshem tawm tom qab vuam tiav.Nyob rau hauv ib txwm ua haujlwm, cov hlau sawb yuav raug mob ntawm cov yeeb nkab steel, thiab cov ntawv tsis siv neeg winding, laser tsis siv neeg vuam, thiab qib siab ntawm automation tiav.

Kauv finned tubes yeej ib txwm tau tsim los ntawm kev siv ntau zaus vuam, brazing lossis inlaying.Cov txheej txheem ntau lawm no ua rau kev hloov pauv cua sov thiab ua kom txias ntawm lub raj finned tsis siab heev, thiab yuav tsis muaj zog vuam thiab de-soldering.Qhov tseem ceeb tshaj, tom qab kev siv vuam ntau zaus, qhov kub thiab txias yog qhov loj heev, uas yooj yim ua rau lub raj finned xeb, uas txwv kev siv ib puag ncig ntawm finned raj.Nyob rau hauv ib puag ncig corrosive, lub finned raj yuav corroded tom qab siv sij hawm luv luv.Txawm hais tias stainless hlau finned raj yog welded los ntawm lub siab zaus, nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, feem ntau vim tias cov fins nqus cov cua sov ntau dhau thiab qhov kub siab dhau, uas cuam tshuam rau cov txheej txheem atomic ntawm stainless hlau.Temper stainless hlau, yooj yim rau xeb thiab txo corrosion kuj.Laser vuam tsis tas yuav xav txog cov teeb meem zoo li no.Laser vuam yog ua tiav nyob rau hauv ib qho instant, thiab cov welded fins tsis muaj kev cuam tshuam rau cov cua sov rov qab.Lub corrosion kuj ntawm stainless hlau tsis txo qis, yog li nyob rau hauv muaj zog acid thiab alkali ib puag ncig, laser vuam finned hlab yuav tsum muaj peev xwm.
