Pressure-on nuts and welded nuts are two commonly used methods for securing nuts. Both methods are used to secure nuts, but their applications differ significantly. Below is a detailed analysis of the differences between press-on nuts and welded nuts.
1. Materials:
1. Press-on nuts: Made from high-quality metal materials, they offer excellent wear resistance, toughness, and tensile strength. Surface treatment and hydrogenation provide excellent corrosion and wear resistance, and they can be used under anodic protection such as zinc, aluminum, and galvanized steel.
2. Welded nuts: Welded nuts are primarily made from aluminum alloy, carbon steel, and stainless steel. They offer excellent corrosion resistance, can operate in air and water, and possess very high pressure resistance.
2. Features:
1. Press-on nuts: Easy to install, safe and reliable, with strong self-tapping power and material savings. They can eliminate the need for plier tapping during welding. Furthermore, this method eliminates the need for heat exposure, is easy to disassemble, and poses minimal risk to personnel and equipment.
2. Weld Nuts: These nuts have a wide range of applications and can withstand high temperatures, high pressures, heavy loads, and harsh environments. They are particularly suitable for high-volume or direct assembly applications, enabling automated welding and high-quality welds with a long service life.
3. Applications:
1. Compression Rivet Nuts: These nuts are primarily used for general mechanical assembly, such as the assembly of mechanical equipment and its components, and laboratory instruments. They can be used for thin plates requiring high precision, improve the uniformity of force distribution on the screws, and ensure reliable weld quality.
2. Weld Nuts: These nuts are primarily used to prevent high-pressure deformation in equipment, weld stainless steel parts, secure connections with high material requirements or high loads, and secure large equipment and components.
