Cov Nta Tseem Ceeb ntawm A5.4 E309-16 Stainless Steel Welding Electrode

Hauv kev tsim thiab kho hlau, kev xaiv cov khoom siv kom haum yog qhov tseem ceeb rau kev ua kom muaj kev sib txuas zoo, kev tiv thaiv corrosion, thiab lub zog sib koom ua ke.Stainless Hlau Vuam Electrodeyog ib qho khoom siv tshwj xeeb uas tsim los ua kom tau raws li qhov xav tau ntawm kev koom ua ke cov hlau tsis xeb thiab cov hlau sib txawv. Tsab xov xwm no tshuaj xyuas cov yam ntxwv thiab kev siv ntawm ib qho kev faib tawm tseem ceeb, AWS A5.4 E309-16.

Lub electrode A302, ua raws li AWS A5.4 E309-16 specification, yog ib hom Stainless Steel Welding Electrode tshwj xeeb. Nws muaj ib txheej rutile (titanium-calcium) uas muab tso rau ntawm ib lub hlau core nrog rau 23% Chromium thiab 13% Nickel. Hom txheej no tseem ceeb heev, vim nws muab kev ruaj khov zoo heev thiab tso cai rau kev ua haujlwm du siv Alternating Current (AC) lossis Direct Current (DC) fais fab, muab kev ywj pheej hauv ntau yam chaw ua haujlwm thiab thaj chaw.

Ib qho haujlwm tseem ceeb ntawm qhov noStainless Hlau Vuam Electrodeyog rau kev koom ua ke ntawm cov hlau sib txawv. Cov hlau vuam uas tau tso los ntawm E309-16 electrode yog cov hlau tsis xeb austenitic nrog cov ntsiab lus alloy ntau dua li cov qib zoo li 304. Qhov no ua rau nws zoo tagnrho rau kev vuam cov hlau tsis xeb overlays (cladding) rau ntawm cov pa roj carbon lossis cov hlau tsis tshua muaj hlau thiab rau kev koom ua ke ntawm cov hlau sib txawv, Hom 304 stainless rau cov hlau tsis muaj zog. Cov hlau vuam uas tshwm sim yog tsim los tiv thaiv kev dilution los ntawm cov khoom siv hauv paus, yog li tswj kev tiv thaiv corrosion thiab tiv thaiv kev tawg.

Cov txiaj ntsig ua haujlwm ntawm lub electrode no ua rau nws siv dav. Lub txheej rutile ua rau yooj yim tshem tawm cov slag thiab tsim cov qauv weld bead du thiab zoo nkauj. Cov weld deposit ua rau muaj kev tiv thaiv zoo rau kev tawg thiab oxidation ntawm qhov kub siab, uas yog qhov tseem ceeb rau cov khoom uas raug thermal cycling lossis kev pabcuam kub siab. Cov yam ntxwv no ua rau chav kawm ntawm Stainless Steel Welding Electrode no yog qhov kev xaiv txhim khu kev qha rau cov ntawv thov tseem ceeb.

Kev faib tawm E309-16, piv txwv los ntawm cov khoom A302 electrode, ua haujlwm ua qhov siv tau ntau yam thiab tseem ceebStainless Hlau Vuam ElectrodeNws cov chromium thiab nickel siab, ua ke nrog cov txheej rutile yooj yim rau tus neeg siv, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev cladding, koom nrog cov hlau sib txawv, thiab vuam qee cov hlau high-chromium thiab high-manganese. Kev nkag siab txog cov khoom tshwj xeeb ntawm Stainless Steel Welding Electrode no tso cai rau cov engineers thiab welders xaiv cov khoom siv zoo tshaj plaws rau kev ua kom ruaj khov, corrosion-resistant welds hauv cov chaw ua haujlwm xav tau.
