What are the classifications of studs? What are the types of welding studs

The difference between the two is that the arc stud welding machine is to continuously use the arc arc to melt the sheet metal at high temperature to make the two welded together; The capacitor stud welding machine uses the capacitor to store the current, instantly release a strong current, detonate the head of the welding nail and the sheet metal, and make the two welded together.

It is divided into several types such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

Self-locking nuts, locknuts, lock nuts, four-jaw nuts, screw-in nuts, safety nuts, thin rod screw connection nuts, self-locking hexagonal cover nuts, nuts for special anchor screws, hexagonal crown thin nuts, eyebolt nuts.

Fine tooth all-metal hexagonal flange face lock nut, all-metal hexagonal flange face lock nut, fine tooth non-metallic insert hexagonal flange face lock nut, fine tooth hexagonal flange face nut. Welded square nuts, welded hexagon nuts, buckle nuts, flushed round nuts. Slotted round nuts, side hole round nuts, end face round nuts with holes, small round nuts.

Round nuts, ring nuts, wing nuts.

The emergence and development of stud welding machine has only gone through a few decades of process, and stud welding has the advantages of full-section welding, standardized operation, high efficiency and reliable quality of stool grinding. With the continuous development of this process, it has been widely used in the industrial field.

According to the different working principles of stud welders, stud welders are generally divided into two categories: energy storage stud welders and arc stud welders.

1. Energy storage stud welding machine.

The energy storage stud welding machine is composed of welding power supply, rectifier, energy storage capacitor, controller, welding gun, ground pliers, welding cable and other parts.

2. Arc stud welding machine.

The arc stud welding machine is composed of a welding power supply, a controller, a welding gun, a ground pliers, a welding cable and other parts. But the welding power supply of most welding equipment is combined with the tubing controller, which is called the main engine.

Screws are indispensable industrial necessities that use the physical and mathematical principles of the bevel of an object to rotate and friction to tighten the mechanical parts of the object step by step.

In fact, screws are a general term for fasteners, and those with external threads can be called"Screws"Screws are also called screws and screws. Screws are generally called wooden screws, which are the kind with pointed ends at the front end, and the pitch is large, and they are generally used to fasten wooden parts and plastic parts; The screw rod is a machine screw, which is the kind with a flat head at the front end, with a small and uniform pitch, and is generally used to fasten metal and machine parts.

Classification of screws.

Screws can be divided into many categories according to different uses: the main categories include ordinary screws, machine screws, self-tapping screws and expansion screws; Machine screws can be divided into longitudinal fastening screws and transverse expansion screws; It can also be divided into triangle threads, pipe triangle threads, trapezoidal threads, and square threads according to threads.

Common materials for screws.

Common screw materials are carbon steel (low carbon steel, medium carbon steel, high carbon steel and alloy steel), stainless steel, aluminum alloy, brass, bronze, antimony copper, etc.

There are three types of screws: ordinary screws, self-tapping screws, and expansion screws. Self-tapping screws: Self-tapping screws refer to wooden screws with pointed heads, thick teeth, and hard textures, as well as aluminum alloy and plastic, and a special self-tapping screw used for metal hole threading is called tapping.

Expansion screw: Expansion screw refers to metal expansion screw, and the fixing of expansion screws is to use the wedge-shaped slope to promote expansion to produce friction grip and wrapping force to achieve the fixing effect. <

There are three types of screws: ordinary screws, self-tapping screws, and expansion screws.

1. Ordinary screws: Screws are tools that use the physics and mathematical principles of the oblique circular rotation and friction of objects to tighten the mechanical parts of the utensils step by step.

2. Self-tapping screws: Self-tapping screws are wooden screws with pointed heads, thick teeth, and hard texture, as well as aluminum alloy and plastic, and a special self-tapping screw used for opening threads through metal holes is called tapping.

3. Expansion screw: Expansion screw refers to metal expansion screw, and the fixing of expansion screw is to use wedge-shaped slope to promote expansion to produce friction grip and wrapping force to achieve the fixing effect.
