Stainless hlau vuam Electrode AWS E310-16 (A402)

APPLICATIONS:

Siv rau vuam ntawm tib yam ntawm cov cua sov-resistant stainless hlau ua hauj lwm nyob rau hauv high kub tej yam kev mob, thiab kuj rau welding ntawm hardened chrome steels (xws li Cr5Mo, Cr9Mo, Cr13, Cr28 thiab lwm yam) thiab sib txawv steels

CHARACTERISTIS:

E310-16yog Cr26Ni21 stainless hlau electrode rau rutile daim tawv nqaij cov khoom siv.AC thiab DC tuaj yeem siv rau txhua txoj haujlwm vuam.Cov electrode no muaj cov txheej txheem vuam zoo, thiab cov hlau tso tau zoo heev oxidation tsis kam nyob rau hauv 900-1100 ℃ kub kub.

CEEB TOOM:

1. Ua ntej vuam, cov electrode yuav tsum tau ci ntawm 300-350 ℃ rau 1 teev thiab siv raws li xav tau.
2. Tshem tawm xeb, roj, noo noo thiab lwm yam impurities ua ntej vuam.
3. DC fais fab mov raug pom zoo, vim tias qhov tob ntawm qhov vuam tam sim no yog qhov ntiav, qhov tam sim no yuav tsum tsis txhob loj dhau, kom tsis txhob muaj qhov liab thiab tawg ntawm daim tawv nqaij.
4. Txo cov cua kub tawm kom ntau li ntau tau, thiab lub viav vias amplitude ntawm electrode yuav tsum tsis txhob loj dhau.
5. Preheat thiab khaws qhov kub ntawm cov channel hauv qab 150 ℃.

WELDING POSITIONS:

PA, PB, PC, PD, PE, PF

CHEMICAL COMPOSITION ntawm tag nrho cov vuam hlau: (Wt. %)

MECHANICAL PROPERTIES NTAWM WELD METAL:

TSEEM CEEB NTAWM CHAW UA HAUJ LWM: (AC lossis DC +)

Ntim:

5kg / thawv, 4boxes / carton, 20kgs / carton, 50cartons / pallet.21MT -26MT ib 1X20 "FCL.

Tightness soj ntsuam ntawm welds:

Rau welds uas nws ua hauj lwm siab yog tsawg tshaj li 0.3MPa, kerosene yuav siv tau rau sealing xeem.Kev ntsuas yuav tsum tau ua raws li cov cai hauv qab no: 5.1.1.1 Qhov ntsuas kub thaum lub sijhawm ntsuas yuav tsum tsis txhob qis dua 5 ° C.

Txheej sab nraud ntawm daim ntawv xeem nrog cov hmoov dawb, thiab lub tsho loj txaus kerosene rau sab hauv.Feem ntau, tom qab 15 mus rau 30 feeb, yog tias tsis muaj cov roj dub nyob rau ntawm cov hmoov dawb, qhov vuam raug suav tias yog qhov tsis zoo.Ntawm qhov tsis sib xws, nws yog qhov yuav tsum tau tshem tawm qhov chaw tsis raug thiab rov ua dua, thiab tom qab ntawd ua qhov kev sim.

Thaum siv hydraulic siab los ntsuas qhov nruj ntawm lub thawv, nws yuav tsum tau ua raws li cov cai hauv qab no:

Kev ntsuas siab yuav tsum tau nce qeeb kom tsis pub tsawg dua 1.5 npaug ntawm kev ua haujlwm siab.

Thaum lub vuam ncav cuag qhov kev ntsuas siab, lub siab yuav tsum tau khaws cia rau 5 feeb.Yog tias pom muaj dej los yog dampness ntawm qhov vuam, qhov tsis xws luag yuav tsum tau cim, tshem tawm, rov welded, thiab tom qab ntawd sim.

Thaum lub sij hawm ntsuas siab ntawm lub workpiece, nws tsis raug tso cai los kho qhov vuam;thiab thaum lub workpiece nyob rau hauv kev sim siab, nws tsis raug tso cai los ntaus lub vuam.

Mechanical Performance Test ntawm welds:

Kev kuaj sampling yuav tsum tau muab coj los ntawm cov qauv nrog tib cov khoom thiab cov txheej txheem ntawm cov khoom siv welded.

Hom thiab qhov loj ntawm qhov kev xeem ua haujlwm yuav tsum ua raws li cov qauv tsim nyog ntawm GB / T 2649 ~ 2653.
