China DIN 929 Refined Welded Nuts Suppliers - Hexagonal Welding Nuts from Factory, Grade 4.8 to 12.9
Functional Configuration
Functional
Hexagonal welded nuts serve as connections. Use a welding machine to connect the hexagonal welding nut to the mother body, and then use screws to fix the required object. Generally used in conjunction with spot welding machines, it has good welding performance and fast efficiency. This type of nut is widely used in industries such as automotive seats, sheet metal chassis and cabinets, molds, ships, railways, etc.
Product features
featuresHexagonal welded nuts solve the problem of ordinary nuts being unable to secure the parent body. There are three welding points and a circular protrusion on one side of the nut. The protrusion is used for positioning, and the solder joint is used for welding. Firstly, punch out a positioning hole on the mother body, position the protrusion of the nut on the hole, and then use a spot welding machine to weld the nut onto the mother body. The welding principle is to melt the three welding points of the nut at high temperature, causing the welding points to melt on the parent body, achieving the welding effect. This connection method belongs to non detachable connection.
Superiority
productsProjection welding has accurate positioning and consistent dimensions, with uniform strength at each point and reliable welding. Projection welding can ensure that the threads do not anneal without reducing accuracy, and the appearance of the welded parts is beautiful with high productivity. There is no harm to the human body caused by CO2 gas and coating smoke, which can improve the working environment.
Shortcoming
PRODUCTSDue to incorrect selection of process parameters, the protruding welding nuts are not firmly welded, and semi-finished parts are prone to falling off during transportation or transportation.
Application and Development History
ApplicationWith the continuous improvement of the quality of welded nuts and the needs of the industry, various types of welded nuts have emerged. The application of welded nuts is becoming increasingly widespread, especially in the automotive industry, where they are applied in important parts such as chassis beams, transmissions, and seat belts. Hexagonal welded nuts are convenient to use, highly efficient, and have a beautiful welding appearance. More and more products are using hexagonal welded nuts.
Frequently Asked Questions
Q1: What is the main function of hexagonal welded nuts?
Hexagonal welded nuts serve as connections. They are welded to a parent body (mother body) using a welding machine, allowing screws to be inserted to firmly fix the required objects.
Q2: How are hexagonal welded nuts positioned and welded?
These nuts feature a circular protrusion on one side for positioning and three solder points for welding. A positioning hole is punched in the parent body to align the protrusion, and then a spot welding machine is used to melt the three welding points at high temperature to weld the nut onto the body.
Q3: What are the key advantages of projection welding for these nuts?
Projection welding provides accurate positioning, consistent dimensions, uniform strength, and reliable welds. It ensures that threads do not anneal, maintains thread accuracy, boosts productivity, and creates a safer work environment free from CO2 gas and coating smoke.
Q4: What can cause welded nuts to fall off, and how can it be avoided?
If incorrect process parameters are selected during welding, the protruding nuts may not weld firmly. This makes the semi-finished parts prone to falling off during transportation. Selecting the correct parameters is crucial to ensure a strong, non-detachable connection.
Q5: In which industries are hexagonal welded nuts most commonly applied?
They are widely used in the automotive industry (particularly for chassis beams, transmissions, and seat belts), sheet metal chassis and cabinets, molds, shipbuilding, and the railway industry.
