1、 Three point welding screw
1. Features: Three point welding screws are a way of connecting by welding the screws onto the workpiece to form three welding points. It has the following characteristics:
(1) Stable connection: Three welding points are located at the head and both sides of the screw, making the contact between the screw and the workpiece closer and the connection more secure.
(2) Wide application range: Three point welding screws are suitable for connecting various metal workpieces, whether it is thin or thick plates, can be connected in this way.
(3) Simple process: The production process of three-point welding screws is relatively simple, requiring only welding equipment and screws to complete, without the need for additional processing steps.
2. Application areas: Three point welding screws are widely used in automotive manufacturing, home appliance manufacturing, aerospace and other fields. For example, in automobile manufacturing, three-point welding screws are commonly used to connect the body and chassis, increasing the stability and rigidity of the entire vehicle.
3. Advantages and disadvantages:
(1) Advantages: The three-point welding screws are firmly connected and can withstand large torque and tension. Meanwhile, the production process is simple and the cost is relatively low.
(2) Disadvantage: Due to the need to heat screws and workpieces during the welding process, thermal deformation and residual stress may occur, affecting the quality of the connection.
2、 Spot welding screws
1. Features: Spot welding screws is a method of connecting the welded part of the screw to the workpiece through spot welding. It has the following characteristics:
(1) Fast welding speed: Spot welding screws have a fast welding speed and can be connected in a short time.
(2) Strong applicability: Spot welding screws are suitable for connecting various metal materials, whether it is thin or thick plates, and can be connected in this way.
(3) Secure connection: The welding points formed between the spot welding screw welding part and the workpiece are sturdy and reliable, and can withstand large moments and tensile forces.
2. Application field: Spot welding screws are widely used in fields such as automotive manufacturing, home appliance manufacturing, and electronic equipment manufacturing. For example, in automobile manufacturing, spot welding screws are commonly used to connect the body and chassis, increasing the stability and rigidity of the entire vehicle.
3. Advantages and disadvantages:
(1) Advantages: Spot welding screws have a fast welding speed and can significantly improve production efficiency. At the same time, the welding points formed between the welding part and the workpiece are firm and reliable.
(2) Disadvantage: The production process of spot welding screws is relatively complex, requiring specialized welding equipment and process control. In addition, the welding part of spot welding screws may cause damage to the surface of the workpiece.
Conclusion:
Three point welding screws and spot welding screws are two common screw connection methods. The three-point welding screw is connected by welding the screw head and three welding points formed on both sides, with a wide range of applications and a simple manufacturing process. Spot welding screws are made by spot welding the welded part of the screw with the workpiece, which has a fast connection speed and strong applicability. Both connection methods have their own advantages and disadvantages, and the appropriate connection method should be selected according to the specific situation. Both three-point welding screws and spot welding screws play an important role in industrial production, providing reliable connection solutions for the development of various industries.
