Dab tsi yog ntau hom vuam alloys?

Vuam alloys yog cov ntaub ntawv tshwj xeeb uas tau tsim los koom nrog cov cuab yeej ua hlau los ntawm kev ua pas dej weld, ua kom cov pob zeb sib xyaw uas phim cov khoom siv hauv paus uas phim cov khoom siv. Lawv tau raug cais tawm los ntawm lawv cov ntsiab lus, txhua tus ua haujlwm ua haujlwm nrog cov hlau thiab ib puag ncig. Los ntawm cov hlau alloys rau cov txheej txheem ua haujlwm rau titanium alloys rau aerospace, txhua hom muaj cov txiaj ntsig tshwj xeeb rau kev siv vuam kev siv sib txawv.
Hlau -} Raws Vuam alloys
Hlau - Raws li cov neeg siv hluav taws xob feem ntau yog cov muaj zog thiab sib xyaw nrog cov hlau roj, qis} cov hlau alleoy.
Cov Hlau Txhim Kho Hlau Alloys
Cov no yog cov hlau, nce mus txog 0.25% carbon, thiab me me ntawm manganese txhawm rau txhim kho weldability. Lawv yog cov mus - rau dav dav {{pitt} lub hom phiaj vuam. Cov piv txwv tseem ceeb muaj xws li e70s ec0s - 6 (lub Mig xaim) thiab E6013 (ib qho khoom siv hluav taws xob). E70s {-} 6 muaj silicon thiab manganese, uas ua raws li deoxidizers kom txo porosity los ntawm kev nqus cov pa hauv lub pas dej weld. Lawv yog qhov zoo tagnrho rau kev siv hlau me me hauv cov phiaj xwm me, cov khoom lag luam automotive, kav dej, thiab diy hlau. Cov alloys sib phim me me steel lub tensile lub zog (60,000-70,000 psi) thiab tsim cov ntaub ntawv huv, sib xyaw. Lawv ua haujlwm nrog txhua cov txheej txheem tseem ceeb (MIG, TIG, FEMAS, Flux-Core). Rau mig vuam, Khub nrog 75% CIAM sib xyaw kom npog cov weld los ntawm cov pa taws ntawm cov pa taws.
Tsawg -} allloy steel alloys
Cov alloys ntxiv chromium, molybdenum, lossis npib tsib xee rau cov hlau hlau, txhawb nqa lub zog, tawv, lossis kub tsis kam. Lawv yog cov tseem ceeb rau qhov siab - kev siv ntxhov siab. E8018 {- b2 (ib lo lo hlua hluav taws xob) suav nrog chromium thiab molybdenum ib puag ncig zoo li lub hwj chim cog kav. ER80S - d2 (ib lub xaim xaim me me) ntxiv rau npib tsib xee, piv txwv li cov raj mis txias (piv txwv li, arctic pipelines). Lawv tau siv rau cov hlab ntsha siab, roj thiab roj tshuab, thiab cov tshuab cov cav hnyav uas yuav tsum tau tiv thaiv huab cua siab, txias, lossis cua sov. Cov alloys tiv thaiv tawg ntho kev ntxhov siab, txawm tias nyob rau hauv cov huab cua phem. Cov ntawv tuab yuav tsum muaj preheating f) kom qeeb cua txias thiab tiv thaiv hydrogen {}} Qhov teeb meem loj thaum muaj huab cua txias.

ER308L (MIG / TIG hlau) yog siv rau weld 304 stainless hlau. Qhov "l" sawv rau cov pa roj carbon tsawg, tiv thaiv chromium carbides uas tsis muaj zog corrosion tsis kam nyob rau hauv high}}} huab cua tshav kub. ER316L (MIG / TIG hlau) muaj molybdenum, tiv taus ntsev thiab tshuaj khib nyiab, khoom tso tsheb hlau. Lawv zoo tagnrho rau txhua daim ntawv thov uas xeb yog tseem ceeb {10} cov khoom siv ua noj, cov cuab yeej kho mob, thiab kev tso tsheb hlau loj, thiab kev tso tsheb hlau loj, thiab kev tso tsheb hlau luam. Cov alloys tswj hwm corrosion tsis kam txawm tom qab vuam. Lawv xav tau cov roj av hauv cov roj ntsha (Argon lossis Argon- h helium makes) los tiv thaiv chomium los ntawm oxidation. Tsis muaj kev tiv thaiv kom tsim nyog, chromium reacts nrog oxygen, txo cov xeb, txo cov xeb.
Tooj liab -} Raws Vuam alloys
Tooj liab - Raws alloys yog tsim rau tooj liab, tooj dag, thiab tooj dag, muab kev coj ua zoo thiab corrosion tsis kam.

Cov alloys (tooj liab nrog 2-5% silicon, ntxiv tin lossis manganese) yog kev ua haujlwm yooj yim. Ercusi - A (ib tug tsov / Mig Hlau) yog tus piv txwv tseem ceeb. Silicon ua li kev deoxidizer, tiv thaiv tooj liab oxide tsim uas tsis muaj zog Welsard. Lawv yog qhov zoo tshaj plaws rau vuam tooj daj, bronze, lossis cov hlau me me hauv cov phiaj xwm kev kho kom zoo nkauj (piv txwv li, cov kev tsheb nqaj hlau). Lawv tiv thaiv corrosion nyob rau hauv dej tshiab thiab muaj qhov sov sov, kub tiav. Lawv ua haujlwm zoo tshaj plaws nrog tig los yog mig vuam, ua ke nrog cov roj av argon, ntws tau yooj yim rau hauv Weld Pas nrog tsawg dua kev tu.
Tooj dag thiab tooj liab alloys
Cov alloys sib phim tooj liab alloys rau kev sib xws. Ercuzn - A (MIG / TIG hlau) muaj cov ntsiab lus zinc tsawg, txo cov evaporation, txo cov evaporation thaum vuam. Zinc Evaponation Ua rau Porosity thiab kev ua tsis muaj zog Welrity, yog li no alloy yog siv rau tooj dag fittings thiab cov khoom zoo nkauj. Ercusn - A (Phosphor Bronze) muaj ntau yam ntxiv dag zog, zoo tagnrho rau bronze gears lossis bearings. Tooj dag alloys yuav tsum tau ceev faj tshav kub tswj- heev ntau ua kom sov ua kom sov ua kom kub kub ua rau kub kub thiab ua kom muaj kuab lom thiab tsim kom muaj cov ntsej muag ntxig.
Aluminium -} Raws Vuam alloys
Aluminium - Raws li cov alloys koom nrog txhuas, kov yeej nws cov oxide txheej kom ntseeg tau tias fusion.
