Tooj liab alloys - Xws li cov nyom vuam, thiab (hauv qee qhov kev sib tw welmast, thiab (hauv qee cov ntsiab lus zoo The best welding type for copper alloys depends on the alloy's composition, thickness, and the project's needs (eg, precision, speed, or portability). Thaum tsis muaj ib txoj kev ua haujlwm rau txhua tus, muaj ntau cov txheej txheem tau ua pov thawj ua tau zoo thaum yoog rau tooj liab lub zog.
1. Tig Vuam (GTAWW): Qhov Kev Xaiv Feem Ntau
Tig vuam (roj tungsten arc vuam) yog mus - ua rau nws cov txiaj ntsig zoo, thiab muaj peev xwm ua kom huv si rau nruab nrab (txog ½ nti). It uses a non-consumable tungsten electrode and inert shielding gas to protect the weld pool, offering unmatched control over heat input-critical for copper's heat-spreading tendency.
Vim li cas nws ua haujlwm rau tooj liab alloys:
Precise Tshav Kub Kub Control: Tig tau kho kom muaj cua sov tsom iav rau ntawm Weld cheeb tsam, kev tawm tsam tooj liab txoj kev nyiam ua kom sov sai sai. Qhov no tiv thaiv underfusion (ib qho teeb meem uas muaj nrawm- Cov hlau cua sov).
Inert Shielding: Argon lossis Argon- hydrogen, tiv thaiv oxidation oxides) thiab porosity (los ntawm hydrogen npuas).
Kev siv lub ntsej muag yooj yim: TIG tso cai yooj yim cov muab cov tsiaj ua kom zoo nkauj (piv txwv li, ercusi {2}, sitenon, phosphorus) kom nqus cov paug.
Zoo tshaj plaws rau:
Nyias mus rau nruab nrab tooj liab alloys (16 kawg li ½ nti).

Tuab tooj liab alloys (½ nti thiab tuab dua), xws li cov kav dej, cov cuab yeej hnyav, lossis cov qauv khoom ua kom zoo nkauj.
Loj - nplai} Cov phiaj xwm kev ceev thiab ua haujlwm ua ntej yog qhov tseem ceeb (piv txwv li cas}}}}}}}}}}}}}}} nickel marine fittings).
Cov lus qhia tseem ceeb rau mig vuam tooj liab alloys:
Xaiv cov tub lim dej nrog deoxidizers (piv txwv li, silicon lossis manganese) los txo cov oxides hauv Weld. Rau tooj dag, siv qis - zinc cov xov hlau kom txo qis zinc evaporation (ib qho kev ua porosity).
Siv lub siab - Amperage tshuab (220V lossis siab dua) kom muaj lub zog arc uas yuav tsum muaj hwj chim ntau dua li cov hlau.
Cia li mus ncig ua si khov kho: txav qeeb heev, thiab thaum kub kis tau kom tsis muaj zog ntawm cov hlau ib puag ncig; txav mus nrawm heev, thiab fusion suffers.
3. Oxy - acetylene vuam: rau portability thiab me- nplai ua haujlwm
Oxy - acetylene vuam yog ib txwm muaj, tsawg} Tus nqi xaiv rau ¼ch capo), muab cov phiaj xwm kev ua haujlwm. Nws siv cov roj {{4 4}}}} e oxygen cov nplaim pleev kom yaj lub hauv paus pib thiab muab tub lim, nrog rau Flux pas dej WELD.
Vim li cas nws ua haujlwm rau tooj liab alloys:
Portity: Tsis xav tau hluav taws xob - qhov zoo tagnrho rau cov chaw deb (piv txwv li, kho lub brass valve rau ntawm ib daim teb).
Cov nplaim hluav taws xob: qhov nruab nrab lossis me ntsis txo cov nplaim hluavtaws me me oxidation, thaum lub caij cua sov tsom mus rau kev tawm tsam tooj liab lub tshav kub.
Kev tiv thaiv flux: Bornax - Recurs Bluxes Daws Plhuav Tawm Liab Oxides Daws Hlau Oxides
Zoo tshaj plaws rau:
Me me, nyias cov tooj liab alloy (piv txwv li, tooj dag fittings, hniav bronze pieces).
Kev khiav teb hloov uas khuam / Mig khoom siv tsis muaj.
Hobbyists lossis DIYers nrog txwv tsis pub nkag mus rau high {{0} iller ignage tshuab.
Cov lus qhia tseem ceeb rau oxy - acetylene vuam tooj liab alloys:
Siv cov nplaim hluav taws neutral kom tsis txhob muaj carburizing (ntxiv carbon) lossis oxidizing cov hlau. Cov nplaim hluav taws xob me ntsis (nplua nuj hauv acetylene) tuaj yeem pab txo cov oxides hauv tooj dag.
Siv flux tau sparingly sparingly mus rau qhov sib koom tes thiab muab tub lim ib qho ({0}}}}} Tshaj flux tuaj yeem trap imp impurities nyob rau hauv weld. Tshem tawm cov ntawv tshaj tawm fluid a tom qab vuam nrog dej kub kom tiv thaiv corrosion.
Tsom cov nplaim hluav taws ntawm lub voj voog weld: txav lub teeb hauv cov voj voog me me kom tsim cov cua sov uas tsis muaj cua sov.
4. Kuj Vuam: Rau siab siab- volume, nyias- daim ntawv thov
Kuj yog vuam (chaw welding los yog leeg vuam) yog siv rau cov neeg tooj hluav taws xob, cov khoom siv hluav taws xob, roj teeb terminals, lossis nyias cov nplooj ntawv tooj liab. Nws ua haujlwm los ntawm kev hla hluav taws xob tam sim no los ntawm kev sib koom ua ke, ua kom muaj cua sov uas melts thiab fuses ntawm cov hlau tsis muaj tub lim.
Vim li cas nws ua haujlwm rau tooj liab alloys:
Ceev: Welds ua tiav rau hauv milliseconds, ua rau nws zoo tagnrho rau high -, tsim brass hluav taws xob txuas txuas).
Tsis muaj tub yees siv: Tshem tawm qhov kev pheej hmoo ntawm cov tub lim - tsis muaj zog, ua kom muaj zog sib koom ua ke.
Tsawg kawg cua sov kis: lub zos cua sov txo kev ua rog hauv cov tooj liab nyias, uas yog qhov tsis sib xws.
Zoo tshaj plaws rau:
Nyias tooj liab alloy cov ntawv (20 ntsuas mus rau 16 lub ntsuas cua).
Cheebtsam hluav taws xob (tooj liab blocks, tooj dag cov terminals) qhov twg huv si, qis {{}}}} Tsis kam sib koom ua ke yog qhov tseem ceeb.
Kev siv cov kab ntau lawm.
Cov lus qhia tseem ceeb rau kev tiv thaiv vuam tooj liab alloys:
Siv lub siab siab los xyuas kom meej zoo hluav taws xob tiv tauj - tooj liab lub siab yuav tsum tau sib koom ua ke kom zoo rau cov cua sov.
Kho cov tam sim no thiab sijhawm ua tib zoo: dhau tam sim no, thiab fusion tsis ua; Ntau dhau, thiab cov hlau hlawv los ntawm.
Huv huv thaj chaw kom huv si: oxides lossis av nce tsis kam, ua rau muaj cua sov tsis sib luag.
5. Laser Vuam: Rau qhov tseeb hauv cov ntawv teev tshwj xeeb
Laser Vuam yog qhov siab - Tech xaiv rau intricate tooj nruas alloy (piv txwv li cov khoom siv kho mob lossis microelectronics) qhov uas xav tau qhov tseeb. Nws siv lub tsom iav ci ci kom yaj cov hlau, nrog cov roj hauv roj kom tiv thaiv oxidation.
Vim li cas nws ua haujlwm rau tooj liab alloys:
