Hauv kev lag luam vuam, qhov ntev - tsis quav ntsej qhov tseeb tau tshwm sim: 70% ntawm cov vuam tsis xws luag yog los ntawm cov khoom siv hauv paus. Roj residues ua rau hydrogen-induced porosity, xeb ua rau tsis tiav fusion, thiab oxide films txo weld zog nyob rau hauv aluminium alloys- tsoos lub kaum sab xis grinders thiab tshuaj ntxuav tsis daws teeb meem. Xwb, lawv ua rau substrate puas thiab efficiency bottlenecks. Laser tu tshuab tam sim no tau tsav qhov kev hloov pauv tseem ceeb hauv kev ua ntej -weld npaj thiab tom qab- vuam txheej txheem.
Lub luag haujlwm ntawm Laser Ntxuav hauv Vuam daim ntawv thov yog dab tsi?
1. Ua ntej-Wel Cleaning: Hais txog lub hauv paus ua rau Vuam tsis xws luag
Thaum ob qhov chaw hlau yog hais txog fuse, microscopic deg paug cov nroj tsuag zais qhov tsis xws luag:
- Ua ntej-weld contaminants (xeb, roj, thiab lwm yam) ua rau weld porosity, tsis tiav fusion, thiab embrittlement;
- Cov yeeb yaj kiab tsis pom oxide tiv thaiv kev sib txuas ntawm cov hlau molecular, ua kom tsis tiav fusion ua rau muaj kev phom sij;
- Rust particles sib tov rau hauv lub pas dej molten hloov alloy muaj pes tsawg leeg, ua rau lub zog degradation.
Laser tu yog ib qho eco-kev daws teeb meem uas ua tau zoo thiab meej tshem tawm cov kab mob ntawm qhov chaw-xws li oxide txheej thiab cov roj residues- tiv thaiv cov vuam tsis xws luag. Nws cov txheej txheem tsis yog -kev sib cuag tiv thaiv kev ncaj ncees ntawm cov substrate, thaum seamless automation kev koom ua ke ua kom zoo dua ua ntej -weld npaj efficiency.
2. Hauv -Welding Tu: Qhov kawg daws rau Interlayer Porosity
Hauv siab- cov ntawv thov nyuaj xws li ntau- hla vuam, cov kab mob sib kis ua rau muaj kev hem thawj rau kev vuam zoo:
- Spatter adhesion ua rau slag inclusions nyob rau hauv lub tom ntej weld passes;
- High -kub oxide nplai txo cov txheej txheem cohesion.
Laser tu ua kom muaj tseeb -lub sij hawm tshem tawm ntawm vuam spatter thaum tus txheej txheem, tiv thaiv slag tsis xws luag los ntawm spatter adhesion. Nyob rau tib lub sijhawm, nws tshem tawm qhov siab -kub oxide nplai, tshem tawm nws qhov kev puas tsuaj rau kev sib koom ua ke ntawm interlayer. Qhov no ua kom huv si weld interfaces thiab zoo interlayer fusion zoo, txo cov vuam tsis xws luag thaum txhim kho kev sib koom ua ke tag nrho.
3. Tshaj tawm -Wel Cleaning: Hloov cov txheej txheem qub
Thaum welding tiav yuav tsum yog qhov kawg, cov txheej txheem ua qauv qhia txog kev sib tw triple:
- Acid pickling drawbacks: Tsim cov dej khib nyiab pov tseg, ua rau muaj kev sib kis loj heev;
- Electrolytic txwv: Cov txheej txheem nyuaj txwv loj- nplai workpieces vim ntim txwv;
- Kev sib tsoo cov kev txwv: Tsawg phau ntawv kev ua haujlwm tsis zoo, kev siv zog ua haujlwm siab, kev ua haujlwm tsis tu ncua, thiab fiber ntau residue ua rau rov ua dua.
Laser tu tshem tawm cov ncej-weld oxides thiab tshav kub tint yam tsis muaj kev puas tsuaj rau lub substrate, xa cov kev huv huv ntawm lub ntsej muag uas ua tau raws li qhov yuav tsum tau ua rau cov txheej txheem qis qis xws li pleev xim thiab electroplating. Nrog xoom tshuaj emissions thiab 60% + kev ua tau zoo dua piv rau cov qauv siv, nws txo qis cov nqi rov ua haujlwm thiab cov nqi ua raws li ib puag ncig.
Cov ntawv thov raug siv ua ntej- Weld thiab Post- Weld Cleaning
Ua ntej- Weld Laser Ntxuav rau Aluminium Alloys
The dense oxide film naturally formed on aluminum alloy surfaces prior to welding induces critical defects such as porosity and slag inclusions. King's Laser ntxuav tshuab tau zoo tshem tawm cov txheej txheem oxide saum npoo no, txhim kho cov txheej txheem vuam, txo qis qhov tsis xws luag, thiab ua kom lub zog thiab kev ntseeg siab ntawm cov pob qij txha welded.
Ncej - Weld Laser Ntxuav rau Stainless Hlau
Thaum tshav kub kub tint nyob rau hauv stainless hlau structural Cheebtsam tom qab vuam adversely cuam tshuam ob qho tib si zoo nkauj tsos thiab corrosion kuj. Mechanical sib tsoo compromises weld kev ncaj ncees thiab degrades mechanical kev ua tau zoo. King's Laser handheld pulsed laser cleaning systems tshem tawm cov xim tsis sib xws thaum txo cov txheej txheem thermal cuam tshuam - xa qhov zoo sib npaug ntawm kev tu kom zoo thiab qhov zoo. Qhov tshwm sim: uniformly huv si, chemically passive nto npaj rau kev siv downstream.
Tshaj tawm -Wel Laser ntxuav rau cov tais roj teeb
Feem ntau aluminium alloy roj teeb tais yog tsim los siv Cold Metal Transfer (CMT®) vuam. Cov txheej txheej dub oxide tsim rau ntawm qhov chaw weld yuav tsum tau tshem tawm tam sim ntawd -tshwj xeeb yog qhov nyuaj nyob rau hauv cov ces kaum sab hauv ntawm T- sib koom ua ke fillet welds qhov twg cov pa phau ntawv sib tsoo tawm qhov muag tsis pom kev. Laser tu muab tag nrho cov oxide tshem tawm yam tsis muaj kev puas tsuaj rau substrate thiab xoom consumable noj.
High-Power Continuous-wave (CW) Laser Ntxuav Tshuab
King's Laser ntxuav cov kev daws teeb meem tau ua tiav qhov loj - kev saws me nyuam thoob plaws qhov siab - kawg kev tsim khoom lag luam - suav nrog kev tsheb ciav hlau, aerospace, cov cuab yeej siv hluav taws xob tshiab, thiab cov tshuab hnyav- ua rau cov neeg siv khoom kov yeej cov tsoos tu lub raj mis thiab ua tiav cov vuam zoo li qub. Saib tom ntej, King's Laser yuav nthuav dav laser tu daim ntawv thov nyob rau hauv precision welding domains, tsav tsheb kev lag luam vuam mus rau seamless txheej txheem kev koom ua ke, ntse tswj zoo, thiab ib puag ncig sustainability- xa ib tug tseem ceeb enabler rau tom ntej no - tiam vuam txheej txheem upgrades nyob rau hauv advanced manufacturing.
