Incomplete Penetration thiab tsis muaj Fusion Defects

Thaum lub sij hawm welding txheej txheem, yog tias tsis muaj kev nyiam rau ib nrab melting ntawm cov hlau phaj thiab vuam electrode, tsis tiav kev nkag los yog tsis muaj fusion defects yuav tshwm sim. Kev nkag mus tsis tiav cov teeb meem feem ntau tshwm sim ntawm lub hauv paus ntawm cov welded sib koom ua ke, tshwj xeeb tshaj yog thaum cov hlau phaj muaj lub thickness loj dua, ua rau qhov tsis tiav kev nkag mus rau qhov tshwm sim ntau tshaj tawm. Thaum lub sij hawm welding ntawm kauv steel kav, tsis muaj fusion yuav tshwm sim nyob rau hauv ib feem ntawm lub weld. Nws yog pov thawj tias kev nkag mus tsis tiav thiab tsis muaj qhov tsis zoo ntawm fusion yog qhov teeb meem loj hauv kev tsim cov kav hlau kav, thiab cov teeb meem no yuav ua rau muaj kev poob qis hauv tag nrho cov kav hlau steel, yog li cuam tshuam rau lawv cov kev siv ib txwm muaj.
