Kev npaj ua ntej-welding ntawm galvanized steel yog tib yam li cov hlau tsis tshua muaj-carbon. Nws yuav tsum tau muab sau tseg tias qhov luaj li cas ntawm txoj kab nqes thiab nyob ze galvanized txheej yuav tsum tau ua tib zoo saib xyuas. Txhawm rau welding, qhov loj ntawm qhov slopes yuav tsum tsim nyog, feem ntau 60 ~ 65 degree, thiab yuav tsum muaj qhov sib txawv, feem ntau 1.5 ~ 2.5mm; Yuav kom txo tau qhov nkag ntawm zinc rau welded seams, ua ntej welding Vuam tom qab txheej yog tshem tawm.
Hauv kev saib xyuas kev ua haujlwm tiag tiag, qhov nruab nrab ntawm qhov nruab nrab tau txais kev pom zoo, tsis tas yuav tawm hauv cov txheej txheem blunt ntug rau kev tswj hwm hauv nruab nrab, thiab ob txheej txheej vuam txheej txheem txo qhov ua tsis tau zoo.
Cov electrode yuav tsum raug xaiv raws li cov khoom siv ntawm cov yeeb nkab galvanized. Feem ntau, nws yog qhov ntau dua los xaiv J422 vim nws yooj yim -rau - ua haujlwm.
Vuam txoj kev: Thaum welding thawj txheej ntawm welded welding, zinc txheej yog melted thiab vaporized, evaporated thiab welds tuaj yeem txo qis heev, uas tuaj yeem txo cov kua zinc hauv cov vuam zoo heev.
Thaum welding welded welded, sim yaj cov zinc txheej thiab vaporize, evaporate thiab sib koom ua ke cov welded seams ntawm thawj txheej. Tom qab melting, rov qab mus rau qhov qub chaw thiab txuas ntxiv mus rau pem hauv ntej.
Thaum vuam thiab sawv vuam, yog tias siv cov slag luv luv xws li J427, qhov tom yuav me me; Yog tias koj siv lub hauv ntej thiab sab nraub qaum ntawm cov tuav, koj tuaj yeem tau txais qhov tsis zoo ntawm vuam zoo.
