Dab tsi yog cov txheej txheem zoo tshaj plaws rau kev ua haujlwm vuam ntawm SPCC boards?
A: Lub vuam tam sim no ntau ntawm 8-12kA thiab electrode siab tswj ntawm 2-4kN tuaj yeem ua tiav cov ntsiab lus weld tsim nyog nrog txoj kab uas hla ntawm 4-6mm.
Vim li cas spatter tshwm sim ntau dhau thaum SPCC board vuam?
A: Qhov no feem ntau yog vim cov vuam tam sim no ntau dhau, tsis txaus electrode siab, los yog impurities xws li roj los yog xeb ntawm lub rooj tsavxwm nto, cuam tshuam rau kev ruaj ntseg ntawm vuam tam sim no thiab lub xeev ntawm lub pas dej molten.
Yuav ua li cas kom tsis txhob porosity tsis xws luag thaum lub sij hawm SPCC board vuam?
A: Ntxuav lub rooj tsavxwm saum npoo ntawm cov roj thiab xeb ua ntej vuam; xaiv qhov tsim nyog welding tsis thiab zam dhau qhov vuam ceev; xyuas kom muaj kev ruaj khov ntawm kev tiv thaiv roj.
Dab tsi yog qhov tsawg kawg nkaus khoov vojvoog ntawm SPCC pawg thawj coj saib?
A: Qhov tsawg kawg nkaus khoov vojvoog tuaj yeem ncav cuag 0.5 npaug ntawm lub rooj tsavxwm thickness. Nws zoo heev dabtsi yog khoov kev ua tau zoo ua rau nws haum rau ntau yam dabtsi yog khoov ua scenarios.
Dab tsi yog qhov kawg kos coefficient ntawm SPCC pawg thawj coj saib?
A: Qhov kawg kos coefficient nws tuaj yeem tiv taus mus txog 0.55. Cov yam ntxwv no tso cai rau nws kom ua tau raws li feem ntau cov duab kos thiab tsim cov txheej txheem ua tiav.
