1.High production efficiency: on the one hand, the wire conductive length is shortened, and the current and current density are increased, so the arc depth and the welding wire dissolution efficiency are greatly improved. On the other hand, because of the heat insulation of the flux and slag, there is basically no radiation loss of heat on the arc, and there is little splash, although the heat loss used for melting the flux has increased, but the overall thermal efficiency is still greatly increased.
2.High weld quality: slag isolation air protection effect is good, welding parameters can be maintained by automatic regulation to maintain stability, welder technical level requirements are not high, weld composition is stable, mechanical performance is relatively good.
3.Good working conditions: in addition to reducing the labor intensity of manual welding operation, it has no arc radiation, which is the unique advantage of submerged arc welding.
4.Can achieve automatic welding. feed the welding wire into the welding area continuously, transmit the welding current, make the arc move along the joint, control the main parameters of the arc, control the starting and stopping of the welding, lay the flux to the welding area, and adjust the wire end position before welding.
5.Automatic welding time: welding parameters can be kept stable by automatic adjustment. Compared with manual arc welding, the degree of dependence of welding quality on welder skill level can be greatly reduced .https://www.wxsilvercoast.com/
