4J36 siv oxyacetylene vuam, hluav taws xob arc vuam, vuam thiab lwm yam vuam txoj kev. Txij li cov coefficient ntawm kev nthuav dav thiab tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau yuav tsum raug zam vim qhov vuam ua rau muaj kev hloov pauv ntawm cov hlau alloy, nws yog qhov zoo dua los siv Argon arc vuam vuam welding muab tub lim hlau nyiam dua muaj 0.5% mus rau 1.5% titanium, thiaj li. txo weld porosity thiab tawg.
