The purchase cost of stud welding equipment is relatively low, and there are many types. According to the product, it can be made into a multi-station automatic welding machine or a high-precision CNC automatic welding machine.

What is the basic principle of threaded stud welder?
The basic principle of threaded stud welder is to ignite the arc between the stud to be welded and the workpiece. When the stud and the workpiece are heated to a suitable temperature, under the action of external force, the stud is fed into the welding pool on the workpiece to form a welded joint. According to the different welding power sources used in the welding process, the traditional threaded stud welder can be divided into two basic methods: ordinary arc stud welding and capacitor energy storage arc stud welding.
What is the method of using stud welding equipment?
1. Arc stud welding. The end of the stud is placed in a ceramic protective cover to contact the base metal and energized with direct current, so that an arc is excited between the stud and the base metal, and the heat generated by the arc melts the stud and the base metal to maintain a certain arc combustion. After time, the pegs are pressed into the local melting zone of the base metal. The function of the ceramic protective cover is to concentrate the heat of the arc, isolate the outside air, protect the arc and the molten metal from the intrusion of nitrogen and oxygen, and prevent the splash of the molten metal.
2. Energy storage stud welding. Energy storage stud welding is to use alternating current to charge a large-capacity capacitor and discharge it instantaneously between the stud and the base metal to achieve the purpose of melting the stud end and the base metal. Due to the limitation of capacitor discharge energy, it is generally used for welding small diameter (less than or equal to 12mm) studs.
What are the types of stud welding?
The method of welding metal studs or other similar metal parts (bolts, nails, etc.) to a workpiece (usually a plate) is called stud welding, and the studs used for welding here are called welding studs. The head of the welding stud generally has an extra head, which is called the welding point, which is not left by carelessness. The welding stud has an internal thread, and the external thread is a welding screw.
There is a small step under the welding point of the welding stud and the welding screw. This is a type of welding screw and welding stud. There is also a welding screw and welding stud that have no steps. It can be understood that they have two shapes. , a type A, with steps, a type B, no steps, is the kind of through-column.
