Welded kev nyab xeeb khau yuav tsum yog kub-tiv taus, rwb thaiv tsev, thiab hnav-tiv taus, tsis-plam kev nyab xeeb khau.
Vim li cas welded kev nyab xeeb khau thiaj li xav tau ntawm cov ntaub ntawv? Vim hais tias cov nplaim taws, arc, kub welds, splashed hlau droplets, liab kub electrode lub taub hau thiab slag nyob rau hauv lub vuam txheej txheem yog lub ntsiab tshav kub qhov chaw rau welding burnt, thiab ib co ntaub ntawv yuav tsum tau welded rau lub weldments ua ntej welding. Preheating, preheating kub tuaj yeem ncav cuag 150 ~ 300 degree; Tsis tas li ntawd, muaj ntau lub cib fim hu rau hluav taws xob thaum lub sij hawm siv hluav taws xob vuam, xws li kev sib txuas tsis raug ntawm cov hlau nyob thiab cov hlau nruab nrab uas tshwm sim los ntawm qhov tsis ua hauj lwm ntawm cov khoom siv vuam los yog cov kab, cov vuam transformer yog thim rov qab, tsis txuas rau hauv high- voltage Circuit Court, raws li zoo raws li cov rwb thaiv tsev puas ntawm cov thawj winding ntawm lub vuam transformer thiab lub thib ob flexing pab pawg neeg, thiab lwm yam, yuav ua rau 220V, 380V voltage tshwm nyob rau hauv lub thib ob Circuit Court ntawm vuam tongs (los yog vuam torch), workbench, thiab lwm yam, yog li qhov hluav taws xob poob siab kuj yog qhov txaus ntshai ntawm kev siv hluav taws xob vuam. ib.
Welded kev nyab xeeb khau yuav tsum muaj cov cua kub tsis kam, rwb thaiv tsev kub, rwb thaiv tsev thiab cov khoom siv kho tshuab.
1, kub tsis kam
Tsawg-kub-resistant vuam kev ruaj ntseg khau yuav tsum tau kub-resistant kub ntawm 150 degree ± 5 degree. High-heat-resistant welding kev ruaj ntseg khau yuav tsum tau kub-resistant kub ntawm 250 degree ± 5 degree. Lub tshav kub tsis kam ntawm cov khau yog muab cov khau rau ntawm ib lub phaj rhuab ntawm adjustable kub, thiab cov khau yog ntim nrog steel pob. Tom qab ntawd cov xuab zeb muab tso rau ib ncig ntawm lub khau thiab qhov siab ntawm cov xuab zeb ncav cuag lub ntug ntawm lub khau, tab sis tsis pub tshaj lub sab sauv. Tos kom qhov kub thiab txias nce mus txog 150 ° C ± 5 ° C, ruaj khov rau 20 feeb. Txias rau hauv chav tsev kub thiab soj ntsuam cov qauv. Cov khau yuav tsum tsis yaj, deform lossis cais.
2, rwb thaiv tsev kub
Vuam kev nyab xeeb khau yuav tsum tau zoo thermal rwb thaiv tsev. Lub midsole ntawm cov khau yuav tsum yog cov khoom siv nrog zoo rwb thaiv tsev. Cov khoom siv ntsuas yog tib yam li qhov ntsuas kub ua haujlwm. Txoj kev sim yog: ntawm 150 ° C ± 5 ° C, tom qab 40 feeb, txhua 5 feeb los sau qhov kub thiab txias ntawm lub insole, thiab mam li xam (los ntawm lub sij hawm tus qauv muab tso rau ntawm lub tshav kub phaj) qhov nruab nrab kub, thiab kuaj Qhov sib txawv ntawm qhov kub thiab txias sab hauv yuav tsum tsis pub tshaj 22 degree.
3, rwb thaiv tsev
Cov hluav taws xob rwb thaiv tsev kev ua tau zoo ntawm welded kev nyab xeeb khau yog ua raws li cov kev cai ntawm GB12011-89 cov khau insulated. Qhov hluav taws xob tiv taus yog 6kV thiab cov xau tam sim no tsis tshaj 3mA.
4, mechanical zog
Lub cev thiab txhua yam khoom ntawm welded kev ruaj ntseg khau ib leeg thiab lub zog tev ntawm cov khau tiav ua tau raws li qhov yuav tsum tau ua ntawm tus qauv rau khau molded (QB1005-90).
Vuam kev nyab xeeb khau kuj tau siv dav hauv kev txiav roj, roj vuam, hluav taws xob vuam thiab lwm yam haujlwm vuam.
