1. Different uses
1. Welding nut: Welding nut is suitable for situations where welding to another workpiece is required. It can simplify the structure and improve the load-bearing capacity of the workpiece. For example, in projects such as water tanks, equipment casings, bridges, etc., nuts need to be fixed on the workpiece to facilitate installation and disassembly, while being able to withstand greater pressure.
2. Ordinary nuts: Ordinary nuts are suitable for those situations that require disassembly, adjustment, installation or tightening. For example, in the fields of automobiles, machinery and equipment, furniture, construction and other fields, ordinary nuts are indispensable fasteners. Common ones include hexagonal nuts, round head nuts, nylon nuts, etc.
2. Different structures
1. Welding nut: The bottom of the nut is tightly connected to the workpiece through welding, usually by spot welding or submerged arc welding. The welding strength is high and the weight is light. The structure is simple without any additional parts, so the price is relatively low.
2. Ordinary nuts: Ordinary nuts are composed of threads, nut heads, bolts and other parts. Nut heads have different shapes, including hexagonal, round, square, etc. There are also many choices of materials such as steel, stainless steel, brass, etc., and the price ranges vary accordingly.
3. Different production techniques
1. Welding nut: The production process of welding nut is relatively simple. It only needs to weld the bottom to the workpiece. The key to welding quality lies in controlling the welding process and welding temperature to ensure the strength of the solder joints.
2. Ordinary nuts: The production process of ordinary nuts is more complicated and requires turning, milling, cutting and other work on the machine to ensure the accuracy and rust resistance of the nut head, bolts and threads.
