Argon-hydrogen mixtures tau txais cov xim tseem ceeb hauv kev sib tw ntawm vuam vim lawv cov khoom ntiag tug thiab cov kev siv ntau ntau. Kab lus no aim rau tshawb nrhiav cov khoom ntau yam ntawm Argon-hydrogen mixtures thiab sib tham txog lawv cov ntawv thov hauv vuam cov txheej txheem. Los ntawm kev nkag siab cov khoom no thiab kev siv, welders tuaj yeem ua kom lawv cov txheej txheem vuaj thiab ua tiav cov khoom siv zoo.

1. Cov khoom ntawm Argon-Hydrogen Mixtures:

1.1 Kev nthuav dav tshav kub ntxiv: Argon-Hydrogen mixtures muaj cov thermal conductivity piv rau cov ntshiab argon. Qhov kev tshwm sim no hauv kev nthuav tawm thaum tshav ntuj sov ntxiv thaum lub sij hawm vuam, ua rau kom txhim kho venetration thiab nrawm dua vuam kev nrawm.

1.2 Txhim Kho Arc Stability: Ntxiv rau ntawm hydrogen rau Argon txhim kho Arc ruaj khov los ntawm kev txo tus voltage poob hla lub arc. Qhov no tso cai rau kev tswj tau zoo dua ntawm cov txheej txheem vuam, kev nthuav dav thiab ua kom muaj arc ruaj khov thoob plaws hauv Weld.

1.3 Kev Tiv Thaiv Kev Tiv Thaiv Roj: Argon-Hydrogen Mixtures muab cov ntaub thaiv zoo heev, tiv thaiv kev sib kis ntawm Weld pas dej. Cov ntsiab lus hydrogen nyob hauv qhov sib xyaw ua cov dej sib xyaw ua cov roj reactive, zoo tshem oxides thiab lwm cov impurities los ntawm weld cheeb tsam.

1.4 txo cov tshav kub kub (Hz): Kev siv ntawm Argon-Heavogen mixtures tau tshwm sim hauv lwm qhov kev thaiv pa. Qhov no yog cov txiaj ntsig tshwj xeeb yog rau kev siv vuam cov ntaub ntawv nrog siab thermal conductivity, raws li nws minimizes distortion thiab txhim kho tag nrho weld zoo.

2. Kev siv ntawm kev sib sib cav-hydrogen mixtures hauv vuam:

2.1 Carbon Steel Vuam: Argon-Hydrogen Mixtures yog ib txwm siv rau cov vuam hlau vuam vim lawv lub peev xwm los muab kev sib tw sib sib zog nqus thiab siab vuam kom nrawm. Kev txhim kho Arc stability thiab txhim kho cov thaiv thaiv cov khoom ua rau cov mixtures zoo tshaj plaws rau kev ua tiav cov ntaub ntawv hlau muaj zog thiab ruaj khov.

2.2 stainless hlau vuam: argon-hydrogen mixtures kuj tseem haum rau stainless hlau vuam. Cov ntsiab lus hydrogen nyob rau hauv cov sib tov sib xyaw pab kom tshem tawm cov oxides, ua rau cov tshuaj ntxuav kom huv nrog cov porosity txo qis. Tsis tas li ntawd, cov lus txhawb hluav taws kub ntxiv rau rau kev siv hluav taws xob nrawm nrawm, txhim kho cov khoom lag luam hauv cov khoom siv stainless hlau.

2.3 Txhuas Vuam: Txawm hais tias kev sib cav sib ceg sib xyaw rau txhuas kev siv rau txhuas kev siv vuam, txuas ntxiv. Cov mixtures muaj zoo dua arc ruaj khov thiab txhim kho tu tu tu, ua rau cov khoom siv zoo nrog txo cov yam tsis xws luag.

2.4 Tooj vuam: Argon-Hydrogen Mixtures tuaj yeem siv rau tooj liab vuam, muab cov arc zoo heev thiab txhim kho cov lus tawm tshiab. Cov tshuaj hydrogen cov ntsiab lus hauv cov sib tov sib xyaw pab kom tshem cov tooj liab oxides, ua kom muaj zog Welds.

Argon-Hydrogen mixtures muaj cov khoom tshwj xeeb uas ua rau lawv haum rau ntau qhov kev siv vuam. Lawv cov tswv yim tshav kub nce ntxiv, txhim kho cov ntaub thaiv npog, thiab txo cov thaiv kom lawv xaiv rau cov hlau, stainless hlau, thiab tooj liab vuam. Los ntawm kev siv cov kev sib cav sib cav sib ceg, hydrogen mixtures, muaj peev xwm ua tiav cov chaw welds zoo nrog kev txhim kho kev tsim khoom thiab txo cov khoom lag luam tsis zoo. Nws yog qhov tseem ceeb rau cov welders kom nkag siab cov khoom thiab cov ntawv thov ntawm cov txheej txheem sib xyaw ua kom lawv cov txheej txheem ua kom tau zoo hauv lawv cov phiaj xwm vuam.
