Stainless hlau vuam Electrode AWS E308-16 (A102)
APPLICATIONS:
Nws tuaj yeem siv rau kev tiv thaiv corrosion ntawm stainless hlau qauv, xws li 06Cr19Ni9 thiab 06Cr19Ni11Ti, uas nws ua haujlwm kub hauv qab 300 ℃;Nws kuj tseem tuaj yeem siv rau cov qauv hlau stainless siv nyob rau hauv qhov kub thiab txias, xws li kua nitrogen ntim, liquefied natural gas ntim, thiab lwm yam.
CHARACTERISTIS:
E308-16yog coated rutile hom Cr18Ni9 stainless hlau.AC thiab DC tuaj yeem siv tau thiab tuaj yeem ua txhua txoj haujlwm vuam.Nws tuaj yeem ncav cuag qhov kev ua tau zoo ntawm vuam, ruaj khov arc, me ntsis spatter, yooj yim slag tshem tawm thiab zoo weld tsos.Cov hlau deposited muaj zoo tiv thaiv inter granular corrosion.
CEEB TOOM:
1. Cov electrodes yuav tsum tau ci los ntawm 320-350 ℃ rau 1 teev ua ntej vuam, qhuav cov electrode thaum siv nws.
2. Cov xeb, roj, dej thiab lwm yam impurities ntawm vuam yuav tsum tau muab tshem tawm ua ntej vuam.
3. Pom zoo DC fais fab mov, vim AC vuam muaj qhov nkag mus rau qhov ntiav, qhov tam sim no yuav tsum tsis txhob loj dhau, txhawm rau kom tsis txhob muaj txheej txheej redness thiab tawg.
4. Yuav kom txo qis cov cua sov tawm tswv yim thiabvuam electrodeoscillating amplitude yuav tsum tsis txhob loj heev.
5. Preheat thiab interlayer-kub yuav tsum nyob twj ywm hauv qab 150 ℃

OEM / ODM:
Peb txhawb OEM / ODM thiab tuaj yeem ua kom ntim raws li koj tus qauv tsim, thov hu rau peb kom paub meej kev sib tham.
Cov kev cai dav dav:
Kev tsim khoom ntawm cov khoom siv welded yuav tsum ua raws li tus qauv tsim, txheej txheem cov ntaub ntawv thiab cov kev cai ntawm tus qauv no.3.2 Qhov yuav tsum tau muaj rau ambient kub thaum lub sij hawm vuam ntau lawm:
Thaum cov khoom thiab cov khoom tiav raug kho, qhov kub thiab txias yuav tsum tsis txhob qis dua li hauv qab no:
Cov khoom siv carbon tsawg: -20 ℃;
Cov khoom siv hlau tsis tshua muaj hlau: -15 ℃.
Feem ntau, qhov tso cai vuam kub ntawm vuam qhov chaw yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm Table.
Thaum welding qhov chaw yog welded nyob rau hauv qis kub tej yam kev mob (raws li teev nyob rau hauv Table 1), lub nto ntawm cov hlau yuav tsum tau preheated.Qhov dav ntawm thaj tsam preheating yuav tsum siab dua 4 npaug ntawm cov phaj tuab yuav tsum tau welded, thiab qhov dav preheating ntawm txhua sab yuav tsum tsis pub tsawg tshaj 100 hli.Vuam tsuas yog ua tau tom qab cua sov rau 100 ~ 200 ℃.Yog siv cov nplaim hluav taws kub ua ntej, qhov kev ncua deb ntawm cov nplaim hluav taws xob thiab lub rooj tsav xwm saum npoo yuav tsum siab dua 50mm.
Nyob rau hauv ib txwm kub tej yam kev mob, rau vuam qhov chaw uas muaj siab rigidity thiab tsis zoo weldability, preheating yuav tsum tau nqa tawm ua ntej welding (lub preheating kub nyob rau hauv thaj tsam ntawm 100 ~ 200 ℃), thiab kub preservation los yog tempering yuav tsum tau nqa tawm tom qab welding. tshem tawm welding kev nyuaj siab.
