General Weldability yam ntxwv
CCS E32 steel phaj muaj qhov zoo weldability. Cov tshuaj muaj pes tsawg leeg ntawm cov hlau no yog tsim nyob rau hauv ib txoj kev uas nws tuaj yeem welded zoo siv cov txheej txheem vuam. Lub xub ntiag ntawm cov khoom tsim nyog alloying pab txo qis kev tsim cov vuam tsis xws li tawg thiab porosity. Piv txwv li, cov ntsiab lus sulfur thiab phosphorus feem ntau yog tswj kom qis, uas txo qhov kev pheej hmoo ntawm kub tawg thaum vuam.
Cov txheej txheem vuam
Shielded Hlau Arc Vuam (SMAW): Nws yog ib txoj kev siv vuam ntau rau CCS E32 steel phaj. Electrodes haum rau vuam siab - lub zog steels raug xaiv. Cov txheej txheej electrode muab cov roj tiv thaiv uas tiv thaiv lub pas dej ua ke los ntawm kev sib kis ntawm atmospheric. Thaum tshav kub kub input thaum lub sij hawm SMAW yuav tsum tau ua tib zoo tswj kom tsis txhob dhau - cua sov thiab distortion ntawm lub hauv paus khoom. Kev xaiv kom zoo ntawm vuam tsis xws li tam sim no, voltage, thiab vuam ceev yog ib qho tseem ceeb los xyuas kom meej lub suab weld sib koom ua ke.
Gas Metal Arc Welding (GMAW): Kuj hu ua MIG (Metal Inert Gas) vuam, GMAW tuaj yeem siv rau CCSE32 steel phaj. Cov roj tiv thaiv xws li argon lossis sib xyaw ntawm argon thiab carbon dioxide yog siv los tiv thaiv lub pas dej ua ke. Cov hlau pub ceev thiab vuam voltage yuav tsum tau kho raws li lub thickness ntawm steel phaj thiab qhov yuav tsum tau weld hlaws loj. GMAW muaj kev kub ceev thiab kev tswj xyuas zoo ntawm cov hlaws vuam zoo.
Flux - Cored Arc Vuam (FCAW): Cov txheej txheem vuam no yog tsim rau cov tuab tuab CCS E32 steel phaj. Lub flux - cored xaim muab ob qho tib si cov khoom muab tub lim thiab tiv thaiv cov nyhuv. Lub slag tsim tom qab vuam yuav tsum tau muab tshem tawm kom zoo los xyuas kom meej qhov zoo ntawm vuam. FCAW tuaj yeem tsim cov welds zoo nrog kev nkag mus zoo thiab cov khoom siv tshuab.

Pre-welding Kev Npaj
Ntxuav: Ua ntej welding CCS E32 steel phaj, nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav qhov chaw yuav tsum tau welded. Txhua yam av, roj, xeb, lossis lwm yam kab mob tuaj yeem cuam tshuam qhov zoo ntawm cov vuam. Abrasive tu txoj kev xws li kev sib tsoo los yog hlau txhuam feem ntau yog siv los tshem tawm cov oxides thiab impurities. Qhov no yuav pab kom muaj kev sib xyaw zoo ntawm cov khoom siv hauv paus thiab cov khoom muab tub lim thaum vuam.
Kev npaj ua ke: Hom kev sib koom ua ke (xws li pob tw pob tw, fillet joint) txiav txim siab txog kev npaj. Rau cov pob qij txha, cov npoo ntawm cov hlau phaj feem ntau yog beveled los xyuas kom meej qhov kev nkag mus ntawm cov weld. Lub kaum sab xis thiab hauv paus qhov sib txawv yog tsim raws li lub thickness ntawm lub phaj thiab cov txheej txheem vuam siv.
Post-welding Kev txiav txim siab
Kev kho cua sov: Qee qhov xwm txheej, tom qab - vuam kev kho cua sov yuav tsum tau txo qhov kev ntxhov siab ntawm vuam thiab txhim kho cov khoom siv ntawm cov vuam sib txuas. Rau CCSE32 steel phaj, kev ntxhov siab - kev kho cua sov ntawm qhov tsim nyog kub (feem ntau qis dua qhov kub ntawm cov khoom siv hauv paus) tuaj yeem txo qhov kev pheej hmoo ntawm qhov txias txias thiab txhim kho qhov tawv tawv ntawm thaj chaw weld.
Kev tshuaj xyuas: Tom qab vuam, ntau txoj kev tshuaj xyuas yog siv los xyuas kom meej qhov zoo ntawm vuam. Cov kev kuaj tsis muaj kev puas tsuaj xws li kuaj ultrasonic, kuaj hluav taws xob, thiab kuaj cov hlau nplaum tuaj yeem kuaj pom qhov tsis xws luag sab hauv thiab saum npoo ntawm qhov vuam. Kev kuaj pom pom kuj tau ua los xyuas qhov tsis sib xws ntawm qhov chaw xws li undercut, porosity, thiab slag inclusions.
