the welding process of submerged arc welding is basically the same as that of the liquid crystal material tester of electrode arc welding. The heat source is also an arc, but the coating on the welding wire is changed into granular flux. Before welding, spread the flux on the weld, about 40 ~ 60mm thick, as shown in Figure 1, which shows the formation process of the weld

during welding, the arc between the welding wire and the weldment is completely submerged and burned under the 40 ~ 60mm thick flux layer. The flux near the arc area is melted under the action of arc heat. In this way, the granular flux and molten flux tightly surround the arc and molten pool metal to isolate it from the outside air. The welding wire is continuously sent to the arc area and moves along the welding direction. The arc also moves, continuing to melt the weldment and flux, forming a large amount of liquid metal and liquid flux. After cooling, welds and welding slag are formed. Because the arc is buried under the flux, it is called submerged arc welding (also known as electric arc welding under the flux layer)

when the welding wire feeding and the welding wire moving forward along the weld in the above process are automatically completed by the welding machine, this is submerged arc automatic welding. The welding process of submerged arc automatic welding is shown in Figure 2. After the joint of the weldment is beveled (no beveling is required below 30mm), tack welding shall be carried out first, and a metal plate shall be placed under the weldment to prevent the outflow of liquid metal. When the welding power is turned on to start welding, the wire feeding wheel is driven by the motor to pull the welding wire out of the welding wire disc and send it to the arc combustion area through the electric conductor. The flux is also sent from the flux bucket to the front of the arc area. Baffles are installed on both sides of the flux to prevent the flux from spreading to both sides. After welding, welds and welding slag will be formed. Part of the unmelted flux is sucked back to the flux bucket by the flux collector for further use
