The role and characteristics of DIN977 welded hexagon flange nuts

What is the meaning of welded hexagonal flange nuts?

Welded hexagonal flange nuts with internal threads and bolts with fasteners, generally weldable materials, and thicker welding strength is relatively large. A wide range of thin and thick can be used, but high temperatures will lead to deformation of the connecting parts and can not be disassembled. Some active metals are welded with the usual methods, such as aluminum and magnesium, and there is a need for shielded gas or TIG welding, as well as the requirements of the process and precision. Precision. A welded hexagon flange nut is a standard fastener widely used in mechanical and structural engineering. It is designed and manufactured with stringent requirements to ensure reliability and stability.

At present, DIN977 welded hexagon flange nuts are cold and upsetting. Generally, cold upsetting will appear to be cold deformation strengthening; however, after welding, often due to welding heat input will reduce the strength of the welded nut to a certain extent, which will make the welded nut lessen the strength of some of the guaranteed load will be diminished, so that the welded guaranteed load will be challenging to meet the required guaranteed load requirements.

The role of DIN977 welded hexagon flange nuts:

Hex weld nuts are hexagonal-type nuts used for welding. The shape is hexagonal; one side is the same as the hexagonal nut, and the other has three weld points and a tab. The three welding points are used for welding, and the tab is used for positioning. Hexagonal weld nuts serve as a connection. A welding machine attaches The hexagonal weld nut to the parent body. Then screws are used to secure the desired object and are generally used with a spot welding machine, which has good welding performance and fast efficiency. This nut is widely used in automotive seats, sheet metal chassis cabinets, molds, ships, railroads, and other industries.

Welded Hexagonal Flange nuts are fasteners used to connect flanges and pipes. In a piping system, flange connection is one of the standard connection methods. The flange connection requires flange face weld nuts to tightly connect the flange to the pipeline. Welded hexagonal flange nuts can play a fixed sealing and bearing role and ensure the pipeline system's regular operation.

Due to the flange welding nut contact surface being more extensive, the torque corner method of tightening, or is connected to the lower strength of the material, will not produce pressure collapse behavior. In addition, due to the flange face welding nut being three convex welding points, the three points form a flat surface in the welding and are more accessible to ensure the parallelism of the welded requirements, so you can prefer to use the flange face welding nut.

What are the specifications and material grades of welded hexagonal flange nuts?

Bolt welded hexagonal flange nut matching design principle is the strength of the welded hexagonal flange nut at least required to match the same level of performance level of the bolt; you can ask to use a higher level of welded hexagonal flange nut to match the lower level of the bolt, to ensure that the assembly will not slip teeth. For example, the welded hexagon flange face nut of grade 8 can match the highest grade of the bolt, which is 8.8.

Welded hexagon flange nuts are generally made of mild steel with good weldability, such as Q235-A can be.

Mild steel: Mild steel, also known as soft steel, has a carbon content of 0.10% to 0.30%. Mild steel is readily accepted in various processes such as forging, welding, cutting, etc. It is commonly used to manufacture chains, rivets, bolts, shafts, etc. The carbon content of less than 0.25% of carbon steel is also known as soft steel because of its low strength, hardness, and softness. It includes most of the ordinary carbon structural steel and a portion of high-quality carbon structural steel, most of which is not heat-treated for engineering structural parts, some by carburizing and other heat treatment for the requirements of wear-resistant mechanical parts. Low carbon steel annealed organization for ferrite and a small amount of pearlite, so it has a lower strength and hardness, plasticity and toughness are better.

A welded hexagonal flange nut is a nut outside the nut suitable for welding, generally, weldable material made of and thicker ideal for welding; welding is equivalent to the two separate parts into a whole, with high-temperature melted metal mixed and then cooled, the middle will be added to the alloy, the internal is a part of the force of the role of the strength is generally more significant than the parent body strength. Experimentation of welding parameters depends on the fusion size of the weld, according to the size of the fusion, to adjust the welding parameters until the shortcomings are cleared. Indeed, the welding quality is good or bad, depending on the pre-welding treatment, clearing ash, oil stains, etc.

They welded hexagonal flange nuts according to ISO21670, Q366, and DIN977 levels 5, 6, 8, 10, and 12. Welded hexagonal flange nuts are increasingly widely used in chassis beams, gearboxes, seat belts, and other vital parts, especially in the automotive industry. Hexagonal weld flange nuts are easy to use and efficient and have a beautiful weld appearance. More and more products are being made using hexagonal flange welding nuts.

Welded hexagonal flange nuts are used relatively less in other industries. Still, other sectors can use thicker steel plate designs, which can be directly processed into the form of internal threaded holes. For bolt welded hexagonal flange face nut pair design requirements, due to the bolt fracture being a sudden occurrence, it is easier to find; and bolts, welded hexagonal flange nut thread slippage is likely to occur slowly is not easy to find, so the bolt welded nut connection in the form of common failures: bolt fracture, bolt thread damage, welded nut thread slippage. Designed to hope or require the occurrence of the failure form in the case of the possibility of over-twisting, bolt weld nut failure form is the bolt fracture failure and can not be a bolt, weld nut thread failure.

ISO 21670 Welding hexagon flange face nuts implementation standards and features:

The structural characteristics of welded hexagon flange flange nuts are mainly reflected in the following aspects. Its six flanges can provide greater tightening force, enabling it to withstand greater loads. Secondly, the central threaded hole of the Welded Hexagon Flange Nut is processed with high precision, which allows it to be accurately matched with threaded rods or bolts to ensure its fastening effect. In addition, welded hexagon flange face nuts have good corrosion and abrasion resistance and can be used long in harsh environments.

Welded hexagonal nuts solve the problem of ordinary nuts being unable to fix the parent body. One side of the nut has three weld points and a rounded tab. The tabs are used for positioning, and the weld points are used for welding. First, the positioning hole is punched out on the mother body, the nut tab is positioned on top of the hole, and then the nut is welded to the mother body using a spot welder. The welding principle is to melt the three welding points of the nut at high temperatures so that the welding points melt on the mother body to achieve the welding effect. This type of connection is a non-removable connection.

Convex welding positioning accuracy and size consistency, the strength of each point is uniform and reliable welding; convex welding can ensure that the thread does not anneal and does not reduce the precision, the appearance of the weldment is beautiful, and high productivity, no CO2 gas and flux skin fumes on the human body can improve the working environment.
