7018 Welding Qws

Nws yog ib qho hluav taws xob alloy electrode.7018 welding pas nrig

Nws cov khoom xyaw tseem ceeb yog marble thiab fluorite, thiab tsis muaj cov organic compounds.

Nyob rau hauv txoj kev siv welding, txoj haujlwm tseem ceeb ntawm cov tshuaj fluorite yog tiv thaiv kom tsis txhob muaj cov roj hauv qhov dej vim qhov marble decomposition los tsim CO2 ua cov pa roj.

Cov nyhuv ntawm kev tshem tawm ntawm hydrogen yog qhov zoo, thiab qhov zoo ntawm cov vuas sib koom tes yog guaranteed.

Thaum lub 7018 welding pas nrig welded, muaj ntau cov tshuaj fluorite (calcium fluoride) nyob rau hauv cov tawv nqaij yeeb tshuaj, yog li arc tsis ruaj tsis khov thaum nws muaj welded nrog hloov tam sim no, thiab DC rov qab electrode yuav tsum tau siv. Thaum tus nqi kom zoo ntawm arc stabilizer ntxiv rau daim tawv nqaij, alternating AC welding uas tam sim no tseem siv tau.

7018 welding rods electrode siv tau rau txhua txoj hauj lwm welding. Nws yog tsim rau vuam tseem ceeb cov qauv xws li qis carbon hlau, nruab nrab carbon hlau thiab qee cov hlau tsis sib haum txhua tus qauv.
