Product introduction
Welding method: turn on the power supply of the welding gun, put the cylindrical stud on the welding gun, prevent the arc seat ring, start the welding gun, the current is fused, and the seat ring produces arc light. After a short time, the cylindrical stud will move the end of the base metal at a certain speed, cut off the power supply, and the column stud will be welded and fixed on the base metal. Welding nail joint is a welding method in which the current is energized between the stud and the base metal, so that the stud and the base metal are partially melted, and the liquid metal is extruded by pressure. At the same time, the whole section of the stud is firmly combined with the base material. It can be divided into arc welding and energy storage welding.
1. Arc stud welding.
The end of the stud is placed in the ceramic protective cover and the base material contact and direct current, so that the arc between the stud and the base material, the heat generated by the arc melting stud and the base metal to maintain a certain arc combustion after a period of time, the stud is pressed into the local melting zone of the base metal. The role of the ceramic protective cover is to concentrate the arc heat, isolate the outside air, protect the arc and the molten metal from nitrogen and oxygen intrusion, prevent the molten metal splashing.
