Kev nkag mus tsis tiav thiab tsis muaj fusion defects

Thaum lub sij hawm vuam txheej txheem, muaj ib qho kev nyiam rau qee qhov ntawm cov hlau phaj thiab vuam electrode tsis yaj rau ib leeg. Qhov no ua rau muaj qhov tsis zoo xws li kev nkag mus tsis tiav lossis tsis muaj fusion thaum vuam. Kev nkag mus tsis tiav feem ntau tshwm sim ntawm cov hauv paus hniav ntawm cov welded sib koom ua ke, tshwj xeeb tshaj yog thaum lub phaj hlau yog tuab, ua rau qhov tsis tiav qhov tshwm sim ntawm kev nkag mus tau zoo dua. Nyob rau hauv cov txheej txheem vuam ntawm kauv steel kav, tsis muaj fusion tuaj yeem tshwm sim nyob rau hauv ib feem ntawm cov vuam. Nws yog pov thawj tias kev nkag mus tsis tiav thiab tsis muaj qhov tsis zoo fusion yog qhov tsis xws luag hauv kev tsim cov kav hlau kav. Cov kev tsis zoo no yuav ua rau muaj kev poob qis hauv qhov zoo ntawm cov kav hlau steel, yog li cuam tshuam rau lawv cov kev siv ib txwm muaj.
