1、 The basic principle of screw welding
Stud welding is a commonly used connection method, which combines the bolts and nuts on the welding material to achieve the connection between two materials. It is a detachable connection method. Stud welding is suitable for situations where two planes need to be connected or irregular materials need to be connected. It has strong load-bearing capacity and good corrosion resistance, and is widely used in fields such as ships, bridges, construction, and machinery.
2、 The usage method of screw welding
1. Preparation work
Before welding the bolts, preparation work needs to be carried out first. Specifically, this includes selecting appropriate bolts, nuts, and welding materials to ensure the surface cleanliness of the welding material and remove any dirt and oxides that may affect the welding process.
2. Welding process
(1) Install bolts and nuts
Before welding, it is necessary to assemble the bolts and nuts at the connecting parts. Assemble according to the specifications and requirements of the bolts, and ensure that the nuts can rotate to facilitate subsequent disassembly work.
(2) Reinforce the appropriate positions of the connecting parts
In order to ensure the quality and stability of welding, it is necessary to reinforce or thicken the connecting parts to increase the load-bearing capacity of the welded joint.
(3) Perform welding
Heat the welding rod as required and make contact with the connecting part for welding. During welding, it is necessary to continuously stir the welding area to fully mix the molten metal, in order to better complete the welding work.
(4) Remove welding slag
After welding, it is necessary to clean the welding slag at the welding site. Use tools such as hammers and pliers to strike and remove welding slag from the surface, making the welding surface smoother.
3、 Precautions for Stud Welding
1. Welding materials should be clean
Before welding, it is necessary to ensure the surface cleanliness of the welding material and remove any dirt and oxides that may affect the welding. Maintaining the dryness of welding materials is also very important.
2. Temperature control is required during the welding process
During the welding process, it is necessary to control the temperature to avoid melting the metal due to excessive temperature or affecting the welding quality due to too low temperature. The selection of welding rods also needs to strictly follow the specifications.
3. Increase reinforcement
In order to improve the load-bearing capacity of screw welding, it is necessary to reinforce or thicken the connecting parts. During the welding process, it is also necessary to heat the connecting parts to enhance the hardness of the material.
In short, screw welding is a common connection method that is very flexible and convenient to use. It should be noted that suitable bolts, nuts, welding materials, and temperature control during the welding process need to be selected when performing bolt welding to ensure welding quality and stability.
