Product Description

As automatically welding device application constantly expanded and automatically welding technology of perfect, large widget using submerged-arc welding of ratio constantly improve,in turn the submerged-arc welding demand in constantly rose. In addition, submerged-arc welding has welding production efficiency high, and welding quality stability reliable, and operation workers labor conditions better, series features, get has widely of application, many important of welding structures use the submerged-arc welding,such as boiler, nuclear power plant container, pressure container, chemical device, large and medium-sized spiral tube, bridge, ship, Vehicles,etc In order to make good welding seam forming, get a good metallurgical reactions, we should according to workpiece structure, welding equipment, welding materials, correct and reasonable selection of corresponding fluxes for submerged arc welding wire and accompanied, by suitable welding process and operating specifications.
