What is the manufacturing process of Carbon Steel Square Weld Nuts?

The manufacturing process of Carbon Steel Square Weld Nuts is a complex process. First, select carbon steel materials that meet specific requirements. This material must have good strength and toughness to ensure that the nut can withstand the corresponding force and pressure during use. The selected carbon steel material needs to undergo rigorous inspection and screening, including chemical composition analysis, mechanical properties testing, etc., to ensure that it meets production standards and customer requirements.
According to the precise size and shape requirements of Carbon Steel Square Weld Nuts, a special stamping die is designed. The design of the die needs to take into account factors such as the plastic deformation characteristics of the material, the tonnage of the stamping machine, and the production efficiency. The inspected carbon steel raw material is placed in the stamping machine. Through the stamping action of the die, the raw material undergoes plastic deformation under high pressure and gradually forms the preliminary shape of the square weld nut. In this process, parameters such as stamping speed, pressure and temperature need to be strictly controlled to ensure the quality of forming.
The stamped square nut is placed on a special welding workbench to ensure that its position is accurate and stable. At the same time, prepare the required solder and welding equipment, such as welding guns, welding rods, shielding gas, etc. Use appropriate welding processes (such as arc welding, laser welding, etc.) for welding. During the welding process, parameters such as welding temperature, time and welding speed need to be strictly controlled to ensure welding quality. At the same time, attention should be paid to the alignment of the weld joint and the formation of the weld pool to avoid welding defects.
After welding, clean the carbon steel square weld nut to remove excess welding slag, spatter and burrs. This can be achieved by grinding, polishing or sandblasting. The appearance and size of the nut are trimmed to ensure that it meets the design requirements. This includes checking the flatness, verticality, dimensional accuracy, etc. of the nut, and reworking or scrapping unqualified products.
Use precision measuring tools to inspect the dimensions of the formed carbon steel square weld nut to ensure that it meets the design drawings and standard requirements. The welding strength of the nut is inspected by tensile testing, hardness testing and other methods to ensure that it can withstand the corresponding force and pressure. Check the surface quality of the nut, including whether there are defects such as cracks, pores, slag inclusions, and whether the surface roughness meets the requirements. Based on the above test results, a comprehensive evaluation is conducted on the Carbon Steel Square Weld Nuts, and only products that meet the standards are allowed to be sold from the factory.
