Kev ceev faj rau kev siv cov khoom
1.Qhov kub ntawm welds yog pom zoo kom tswj tau ntawm li 150 ° C.Thaum multi-pass multi-layer vuam ntawm me me thiab nruab nrab specifications, xyuam xim rau kev tswj cov vuam kab zog.
2.Cov txheej xeb, noo noo, roj, plua plav, thiab lwm yam ntawm qhov vuam yuav tsum tau ntxuav.
3.Lub flux yuav tsum tau ci ntawm 300-350 ℃ rau 2h ua ntej siv.
Cov lus qhia saum toj no tsuas yog siv rau kev siv xwb, thiab qhov xwm txheej tiag tiag yuav muaj yeej hauv kev ua haujlwm tshwj xeeb.Yog tias tsim nyog, cov txheej txheem tsim nyog yuav tsum tau ua ua ntej txiav txim siab txoj kev npaj vuam.
