Automatic multipole depositing welding technology

Making use of Automatic multipole depositing welding technology to provide functional coating with surface strengthening for pinch roll, wrapper roll, continuous casting roll and hot straightening roll, so that roll dimension is effectively recovered, so that the life time is effectively extended. This technology has been successfully widely applied in Baosteel, Baogang ,Liangang steel plant.


Automatic multipole depositing welding technology is a kind of technology which utilizes electric arc between electrical rod and part as hot resource to melt electrical rod, flux and mother material underneath the protective and alloying flux to form recoverable layer and functional protective coating layer.

Through reasonable selecting and proportioning for electrical wire, flux and depositing welding process, heating treatment before and after welding, it can effectively make the series wearing deposited welding layer in more completive metallurgic reaction, high metal purity, ideal alloy composition, hardness from HR35 to HR62, the coating layer is with excellent anti-fatigue, anti-wearing, corrosion resistance, so that the life time is effectively extended.
