Puas xav tau cov roj ntxiv tiv thaiv ntxiv yuav tsum tau ntxiv thaum vuam? Puas tsim nyog peb siv Argon lossis nitrogen?

Cov roj tiv thaiv ntxiv feem ntau yog xav tau thaum vuam cov tee dej, tiv thaiv cov roj av, tiv thaiv kev ua haujlwm ntawm Weld, thiab ua kom muaj kev ncaj ncees ntawm Weld Seam; Nws kuj tseem tuaj yeem tiv thaiv lub lens los ntawm cov hlau vapor vapute thiab txaws ntawm cov kua ntws. Txawm li cas los xij, tseem muaj qee txoj kev vuam kev vuam uas tsis tas yuav tiv thaiv roj, xws li tus kheej tiv thaiv fluex cored hlau vuam vuam. Flux tseem ceeb hauv lub vuam hlau yuav tsim cov roj kev tiv thaiv roj thiab sluag thaum lub rooj sib tw los tiv thaiv cov vuam; Muaj tseem muaj qee cov kev tiv thaiv vuam xws li chaw vuam, uas feem ntau tsis tas yuav muaj roj tiv thaiv ntxiv.

Raws li rau seb yuav yuav xaiv los xaiv kev sib cav lossis nitrogen, nws nyob ntawm cov khoom sib txawv thiab cov txheej txheem. Cov hauv qab no yog cov xwm txheej tshwj xeeb:

Tus sib cav

1. Vuam Stainless Hlau: Argon roj yog ib feem siv siv roj tiv thaiv nyob rau hauv stainless hlau vuam. Ntshiab Agon yog tsim rau tungsten inert roj vuam (Molten yog cov hlau hlau tsis zoo, thiab kev tsim Weld tsis zoo. Feem ntau, 1-2% oxygen ntxiv rau kev sib cav sib ceg kom txo qis nro, txhim kho kev ua kom zoo nkauj rau kev ua kom zoo nkauj Los ntawm kev ntxiv 2-5% Co ₂, lub arc stability yog qhov zoo, cov alloy cov ntsiab tau hlawv tsawg dua, thiab tsis muaj ib tus nyiam ua kom muaj pa roj carbon. Nws yog qhov tsim nyog rau TIG hauv qab Vuam thiab Memours npog Vuam cov txheej txheem rau cov kav hlau ua ke.

2. Vuam aluminium alloys: aluminium alloy gmaw feem ntau siv los ua roj tiv thaiv, uas yuav tsum tau muaj roj av ntau yuav tshwm sim ntawm ob sab ntawm Weld. Yog tias koj xav nce lub vuam vuam thiab nrawm, koj tuaj yeem ntxiv qee yam kev sib cais ntawm nws ntawm nws yog loj dhau lawm, yuav muaj kev sib txig dhau lawm.

3. Vuam tooj liab thiab tooj liab alloys: kev dawb huv A yuav siv tau raws li lub tshuab txhaj tshuaj vuam.

4. Vuam npib tsib xee thiab nickel alloys: ntxiv rau kev siv cov pa hluav taws ntse kuj tseem tuaj yeem ntxiv rau cov roj av txhim kho kev ua kom zoo.

5. Vuam titanium thiab titanium alloys: vim yog txoj kev sib raug zoo ntawm titanium thiab n, H, thiab A, ME, HE, ntshiab AR thiab AR + thiab tsuas yog siv cov gmaw ntawm titanium thiab titanium alloys.

Nitrogen

1. Vuam Stainless Hlau: Nitrides ua los ntawm cov tshuaj lom neeg ntawm nitrogen thiab stainless hlau tuaj yeem txhim kho lub zog ntawm Weld sib koom tes thiab txhim kho cov neeg kho tshuab ntawm Weld. Yog li ntawd, cov nitrogen tuaj yeem siv los ua cov roj tiv thaiv thaum vuam stainless hlau, tab sis nws feem ntau tsis siv ib leeg thiab yog tov nrog argon thiab lwm yam roj av.

2. Vuam tooj liab thiab tooj liab alloys: thaum vuam tooj liab thiab cov tshuaj pleev ib yam, tab sis tej zaum muaj qee cov pa taws thiab pa taws.

Yog tias koj muaj vuam tshuab yuav tsum tau, thov hu rau Ms. Zhao
