Shielded Hlau Arc Vuam (SMAW)

 

Kev xaiv electrode: Rau ASTM A606 TYPE4 steel, electrodes haum rau qis- alloy steel vuam yuav tsum raug xaiv. Cov txheej txheej thiab alloy muaj pes tsawg leeg ntawm cov electrodes yuav tsum ua kom haum cov tshuaj muaj pes tsawg leeg ntawm cov hlau kom ntseeg tau tias vuam zoo. Feem ntau, cov ntsiab lus ntawm cov hlau alloy (xws li tooj liab, chromium, npib tsib xee, thiab lwm yam) hauv electrode yuav tsum nyob ze rau ntawm cov hlau nws tus kheej. Qhov no tuaj yeem muab qhov zoo sib xws rau corrosion thiab mechanical zog thaum lub sij hawm vuam txheej txheem. Piv txwv li, ib qho electrode xws li E7018 - A1 tuaj yeem xaiv. Nws yog tsim rau welding tsawg - alloy steel nrog ib tug tej yam degree ntawm corrosion kuj thiab muaj peev xwm muab zoo weld zog thiab toughness.

 

Vuam Parameters: Lub vuam tam sim no yuav tsum tau txiav txim siab raws li txoj kab uas hla ntawm cov electrode thiab thickness ntawm cov welded ib feem. Feem ntau hais lus, rau ib qho electrode nrog txoj kab uas hla ntawm 3.2 hli, qhov vuam tam sim no tuaj yeem teem caij nruab nrab ntawm 90 - 130 A; rau lub electrode nrog ib txoj kab uas hla ntawm 4.0 hli, qhov tam sim no ntau yam yuav nyob nruab nrab ntawm 140 - 180 A. Qhov vuam ceev kuj tseem ceeb heev. Qhov ceev vuam ceev heev tuaj yeem ua rau tsis zoo fusion ntawm vuam, thaum lub sijhawm qeeb qeeb yuav ua rau lub vuam dhau los thiab cuam tshuam rau kev ua haujlwm vuam. Feem ntau, vuam ceev ntawm shielded hlau arc vuam tuaj yeem tswj tau li ntawm 10 - 15 cm / min. Thaum lub sij hawm vuam txheej txheem, kuj yuav tsum tau them nyiaj mloog mus rau lub arc ntev. Luv - arc vuam yuav tsum tau khaws cia. Feem ntau, qhov ntev ntawm lub arc yuav tsum tsis txhob tshaj qhov kab ntawm lub electrode. Qhov no tuaj yeem tiv thaiv lub pas dej molten zoo dua thiab txo qhov tsis xws luag xws li qhov pores.

Gas Metal Arc Welding (GMAW)

 

Shielding Gas Xaiv: Nyob rau hauv cov roj - shielded vuam, feem ntau siv shielding gases yog carbon dioxide (CO₂) los yog ib tug sib tov ntawm argon (Ar) thiab carbon dioxide (xws li Ar + 20% CO₂). Rau ASTM A606 TYPE4 steel, siv cov roj sib xyaw tuaj yeem ua tiav cov txiaj ntsig zoo dua. Argon tuaj yeem muab qhov chaw ruaj khov thiab kev hloov pauv zoo, thiab cov pa roj carbon dioxide pab txhim kho cov oxidizability ntawm cov vuam thiab txhim kho cov vuam tsim thiab zoo. Cov roj sib xyaw no tuaj yeem tiv thaiv lub pas dej molten zoo, tiv thaiv cov pa oxygen thiab nitrogen hauv huab cua los ntawm kev nkag mus rau hauv lub pas dej molten, thiab yog li txo cov vuam tsis xws li qhov pores thiab tawg.

 

Hlau xaiv thiab Parameter Setting: Kev xaiv ntawm vuam hlau yuav tsum xav txog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv ntawm cov hlau. Feem ntau, cov hlau tsis tshua muaj hlau vuam hlau nrog cov muaj pes tsawg leeg zoo ib yam li cov hlau hauv paus yuav tsum tau xaiv. Piv txwv li, ER70S - 6 vuam hlau yog ib qho kev xaiv uas feem ntau siv. Nws muaj qhov tsim nyog ntawm cov ntsiab lus alloy thiab tuaj yeem ua kom zoo sib xws ntawm cov vuam thiab lub hauv paus hlau. Qhov chaw ntawm vuam tam sim no thiab voltage kuj tseem ceeb heev rau vuam zoo. Thaum siv cov vuam hlau nrog txoj kab uas hla ntawm 1.2 hli, qhov vuam tam sim no tuaj yeem nyob nruab nrab ntawm 180 - 250 A thiab qhov hluav taws xob nruab nrab ntawm 22 - 28 V. Qhov vuam ceev tuaj yeem hloov kho raws li qhov tseeb, feem ntau nyob ib ncig ntawm { {8}} cm/min.
