Tsav los ntawm kev lag luam kev lag luam tsis tu ncua kev thov rau lub teeb yuag, siab - lub zog, thiab corrosion- cov ntaub ntawv tiv taus, stainless hlau raj tau dhau los ua cov khoom tseem ceeb hauv cov tshuab hluav taws xob tsheb, cov kab roj, cov ntawv thov hydrogen, cov khoom siv kho mob, thiab lwm yam. Cov ntawv thov no tsis tsuas yog yuav tsum tau muaj kev tiv thaiv corrosion zoo heev tab sis kuj tseem muaj kev sib sau ua ke nyob rau hauv nruj spatial txwv - tso cov kev xav tau nruj ntawm cov khoom siv vuam zoo, cua sov- cuam tshuam cheeb tsam (HAZ) tswj, thiab tag nrho cov raj formability.
Stainless hlau raj ntau lawm feem ntau pib nrog tsis tu ncua ua ib lub tiaj tiaj tiaj mus rau hauv ib puag ncig lub raj, ua raws li los ntawm vuam cov seam kaw. Qhov zoo ntawm qhov weld no ncaj qha txiav txim siab lub raj cov khoom siv kho tshuab, qhov sib xws ntawm qhov chaw, thiab qhov tsim nyog rau cov txheej txheem qis qis xws li khoov lossis flaring. Niaj hnub no, peb txoj kev siv thev naus laus zis tseem ceeb tshaj plaws hauv kev lag luam: Tungsten Inert Gas (TIG/GTAW) vuam, Siab -Frequency (HF) vuam, thiab Laser vuam.
Raws li cov chaw tsim khoom lag luam ntawm stainless hlau yeeb nkab tsim khoom, ST Machineries leverages xyoo ntawm kev lag luam kev lag luam los soj ntsuam cov yam ntxwv kev, siv tau, thiab muaj peev xwm ntau lawm ntawm peb txoj kev vuam, pab cov lag luam hauv kev xaiv cov khoom siv scientific thiab cov kab ntau lawm optimization.
Siab -Frequency (HF) Vuam: Qhov siab tshaj plaws ntawm tus nqi Weld Quality
HF welding siv siab - zaus tam sim no los ua kom muaj cua sov tiv thaiv ntawm cov npoo ntawm cov hlau sawb ntawm daim tawv nqaij thiab qhov sib thooj. Cov npoo molten yog ces forged ua ke nyob rau hauv siab siab los ntawm nyem yob. Cov tub ntxhais hlau nplaum (los yog "impeder") feem ntau muab tso rau hauv lub raj kom mloog zoo rau cov electromagnetic teb thiab txhim kho lub zog efficiency.
Cov txiaj ntsig tseem ceeb:
- Vuam ceev nce mus txog 120 meters ib feeb- qhov ceev tshaj plaws ntawm txhua txoj kev vuam tam sim no;
- Zoo tagnrho rau siab - ntim, txheem ntau lawm.
Cov kev txwv tseem ceeb:
- Tsim cov burrs tseem ceeb sab hauv thiab sab nraud (weld flash), yuav tsum tau tshaj tawm -weld cov haujlwm xws li deburring, polishing, thiab qee zaum pickling;
- Lub weld cheeb tsam muaj oxides thiab coarse grain qauv, ua rau tsis zoo ductility;
- Tsis ruaj khov thaum vuam siab - alloy stainless hlau (xws li 316L, duplex qib);
- Micro-kev tawg yog qhov nyuaj rau kev tshawb pom nrog cov txheej txheem NDT cov qauv, ua rau muaj kev cia siab rau kev nyab xeeb- cov ntawv thov tseem ceeb xws li tsheb thauj mus los lossis hydrogen.
Automotive Siab - zaus Tube Zeb Tshuab
Yog li, HF welding feem ntau yog siv rau cov qauv tubing, dav dav - lub hom phiaj kev xa tawm cov kua dej, thiab cov ntawv siv kho kom zoo nkauj uas qhov vuam huv thiab kev tsim tsis tseem ceeb.
TIG (GTAW) Vuam: Kev huv huv siab nrog cov khoom nruab nrab
TIG welding tsim ib qho chaw ruaj khov ntawm cov khoom siv tsis yog -tungsten electrode thiab cov khoom ua haujlwm, tiv thaiv los ntawm siab -purity argon roj los tiv thaiv lub pas dej molten los ntawm oxidation. Renowned rau nws spatter-dawb, pore-dawb, thiab du nyob rau hauv weld nto, TIG tau ntev lawm mus- mus rau txheej txheem rau siab - daim ntawv thov kev ncaj ncees.
Cov txiaj ntsig tseem ceeb:
- Nrog cov khoom siv hluav taws xob niaj hnub thiab cov khoom siv zoo tshaj plaws, TIG vuam ceev tam sim no ncav cuag 8 meters ib feeb rau 0.5-2.0 hli phab ntsa thicknesses hauv 304/316L stainless hlau;
- Cov zis txhua hnub (8- teev ua haujlwm) yog kwv yees li 3,840 meters-ib qho kev txhim kho tseem ceeb ntawm cov kab ke qub txeeg qub teg.
Cov yam ntxwv technical:
- Kev siv hluav taws xob ntau dua thiab ua kom txias qeeb ua rau muaj qhov dav HAZ;
- Tsis tas yuav tsum muaj cov khoom siv filler; tsawg heev kom tsis muaj kev tshaj tawm - yuav tsum tau ua tiav;
- paub tab, ruaj khov, thiab zoo - haum rau yoog raws, me me -batch ntau lawm nrog kev hloov pauv ntau zaus.
TIG Welded Stainless hlau yeeb nkab ntau lawm kab
Txawm hais tias nws qis qis dua piv rau HF thiab laser, TIG tseem tsis tuaj yeem hloov pauv hauv cov zaub mov - qib, tshuaj, thiab semiconductor tubing, tshwj xeeb tshaj yog rau kev xa tawm mus rau kev lag luam nrog cov qauv kev cai nruj (xws li FDA, 3-A, GMP).
Laser Vuam: Precision, formability, thiab sib npaug ceev
Laser welding employs a high-power-density beam (typically >1 MW / cm²) tsom rau ntawm lub seam los tsim "keyhole" nyhuv, ua rau lub pas dej sib sib zog nqus, nqaim. Weld dav tuaj yeem tswj tau li ntawm 0.3-0.8 hli, nrog HAZ me me.
Laser Welded Stainless hlau yeeb nkab ntau lawm kab
Cov txiaj ntsig tseem ceeb:
- Tsis muaj oxidation, tsis muaj burrs, tsis muaj cov khoom muab tub lim -cov raj tau npaj rau kev ua haujlwm qis tam sim tom qab vuam;
- Lub zog weld siab, tsis tshua muaj kev ntxhov siab, thiab kev ua kom zoo dua qub, ua rau nws zoo tagnrho rau kev khoov tom ntej, nthuav dav, lossis hydroforming;
- Scrap tus nqi qis dua 2%, nrog rau tag nrho cov txiaj ntsig tshaj 98%;
- Yooj yim kev koom ua ke nrog automation thiab ntse Hoobkas systems (xws li, MES).
Critical Enablers:
- High- brightness fiber ntau los yog slab lasers kom ruaj khov keyhole tsim;
- Laser-raws li seam tracking systems siv CMOS koob yees duab los kuaj qhov sib txawv, tsis sib xws, thiab qhov sib txawv ntawm qhov nruab nrab ntawm lub sijhawm (qhov tseeb ± 0.05 hli), dynamically kho lub laser tsom;
- High -precision forming stands thiab weld boxes yog qhov tseem ceeb los tswj cov ntug kev sib raug zoo li tsawg dua lossis sib npaug li 0.1 mm.

Kev Taw Qhia Kev Xaiv: Txoj Cai Technology rau Txoj Cai Thov
Raws li kev tsim khoom thoob ntiaj teb hloov mus rau qhov zoo dua, kev ruaj khov, thiab digitalization, stainless hlau raj vuam tshuab tau dhau los ua qhov kev hloov pauv loj. Thaum HF vuam xa cov kev sib tw tsis sib xws, nws qhov kev cuam tshuam zoo hauv kev txwv nws lub peev xwm yav tom ntej. TIG welding tseem yog ib qho kev ntseeg siab rau kev huv, tswj kev siv- nrog cov tshuab niaj hnub ua kom tau txais txiaj ntsig zoo. Lub caij no, laser vuam, tam sim no khiav lag luam cia siab rau ntawm 30 meters ib feeb nrog xoom ncej- ua thiab tshwj xeeb formability, yog sai dhau los ua tus qauv rau siab - tus nqi raj ntau lawm.
- Rau tus nqi-tsav, siab- ntim, tsis yog- qhov tseem ceeb (piv txwv li, cov khoom siv hauv tsev) → HF vuam tseem yog qhov kev xaiv pheej yig tshaj plaws, txawm hais tias cov neeg yuav khoom yuav tsum paub txog qhov zais zais - cov nqi ua haujlwm thiab cov kev txwv tsis zoo.
- Rau kev tswj hwm kev lag luam uas yuav tsum tau muaj ntawv pov thawj (FDA, 3-A, thiab lwm yam) → TIG vuam muaj kev txhim khu kev qha, ua raws txoj hauv kev nrog cov khoom siv tau zoo rau feem hwm.
- Rau kev txiav- ntug sectors xws li lub zog tshiab tsheb, hydrogen infrastructure, los yog precision kho mob cov cuab yeej → Laser vuam yog lub tswv yim txawj tej yam ntxiv, xa cov zoo tagnrho tshuav ntawm ceev, zoo, thiab ntse tsim npaj txhij.
Raws li cov cuab yeej tsim khoom, peb pom zoo kom xaiv txoj kev vuam raws li ua ntej kawg - siv cov kev cai, tom qab ntawd ntsuas cov ntim ntau lawm, cov phiaj xwm kev lag luam, thiab ntev - kev lag luam kev lag luam. Saib tom ntej, nrog kev txo qis hauv laser system cov nqi thiab kev nce qib hauv kev tswj xyuas ntse, laser vuam yog npaj los hloov cov txheej txheem ib txwm siv thoob plaws ib puas xyoo - nthuav dav ntawm cov ntawv thov.
