Stainless hlau vuam Electrode AWS E309-16 (A302)

APPLICATIONS:

Haum rau welding tib hom stainless hlau, stainless hlau hauv ob sab phlu, txawv steels (xws li Cr19Ni10 thiab tsawg carbon steel, thiab lwm yam) raws li zoo raws li gaoluo hlau, siab manganese hlau, thiab lwm yam.

CHARACTERISTIS:

E309-16yog Cr23Ni13 stainless hlau electrode rau rutile daim tawv nqaij cov khoom siv.Ob leeg ac thiab DC tuaj yeem siv rau txhua txoj haujlwm vuam.Kev ua haujlwm vuam zoo heev.Cov hlau deposited muaj zoo tawg kuj thiab oxidation kuj.

CEEB TOOM:

1. Ua ntej vuam, cov electrode yuav tsum tau ci ntawm 320-350 ℃ 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 TSHAJ PLAWS: (AC lossis DC +)

Ntim:

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

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.

Txoj cai tshuaj xyuas:

Vuam qhov chaw raug tshuaj xyuas los ntawm lub chaw soj ntsuam zoo ntawm cov chaw tsim khoom.

Rau welds uas yuav tsum tau kuaj radiographic, qhov ntev ntawm cov welds raug kuaj radiographic yuav tsum tsis pub tsawg tshaj 20% ntawm tag nrho ntev ntawm cov welds.

Thaum pom muaj qhov tsis txaus ntseeg hauv qhov vuam, kev kuaj hluav taws xob ntxiv yuav tsum tau ua nyob ze ntawm qhov tsis xws luag, thiab qhov kev tshuaj ntsuam xyuas hluav taws xob ntxiv yuav tsum sib npaug rau qhov ntev ntawm qhov ntsuas hluav taws xob ntawm qhov vuam.Yog tias pom muaj qhov tsis txaus ntseeg tau pom tom qab kev kuaj hluav taws xob ntxiv, tag nrho cov welds yuav tsum tau kuaj hluav taws xob.

Rau qhov tseem ceeb welding qhov chaw, cov tsos thiab cov duab geometric thiab qhov loj ntawm cov vuam yuav tsum raug tshuaj xyuas ib qho los ntawm ib qho.Ntxiv nrog rau qhov kev tshuaj xyuas zoo ntawm cov welds rau qhov chaw dav dav, cov geometry thiab qhov ntev ntawm cov welds yuav tsum tau randomly tshuaj xyuas.
Rau qhov tseem ceeb lossis qhov tseem ceeb welds ntawm qhov tseem ceeb, qhov yuav tsum tau ua rau kev sim tsis muaj kev puas tsuaj los yog kev sib khi thiab kev ntsuas kev sib tw vuam yuav tsum tau ua raws li cov lus qhia tshwj xeeb hauv cov duab kos lossis xaj cov kev xav tau.
