Weld spot refers to the raised part of the weld formed in the welding process. It is formed by the rapid cooling of molten metal paste during welding and is usually round or oval in shape.
Stainless steel welding spot is an inevitable product in the welding process, but too much welding spot may affect the welding strength and appearance quality, so the need to control welding parameters, such as welding current, voltage, welding speed, in order to reduce the number and size of welding spots.
Stainless steel spot
Welding spot is formed in the welding process, the main reason is that after the metal material in the welding area is melted, the liquid metal will form a solidified form in the process of rapid cooling.
The formation of welding spots is related to the following factors:
Welding current and voltage: the size of welding current and voltage directly affects the size and shape of the weld pool, thus affecting the formation of welding seams and the shape of welding spots.
Welding speed: The faster the welding speed, the smaller the weld pool, the faster the cooling rate, the smaller the weld spot.
Welding materials: The chemical composition and melting point of welding materials will affect the shape of the weld and the fluidity of the weld pool, thus affecting the formation of welding spots.
Welding equipment and welding process: Different welding equipment and welding process will produce different heat input and welding conditions, which will affect the shape of welding seam and welding spot.
Atmosphere and environment: The atmosphere and environment during welding, such as oxygen content and humidity, will also affect the welding process and welding quality.
Remove stainless steel welding spots
It is recommended to use magnetic polishing machine to remove stainless steel welding spots. The advantages of magnetic polishing machine to weld spots are as follows:
High efficiency: Magnetic polishing machine can remove a large number of welding spots in a short time, improve production efficiency.
High precision: the magnetic adsorption capacity of the magnetic polishing machine can make the workpiece surface closely fit the grinding steel needle, can obtain higher processing accuracy.
Simple process: compared with the traditional grinding, milling and other methods, the process of magnetic polishing machine to weld spots is more simple and easier to operate.
Good surface quality: After removing welding spots by magnetic polishing machine, the workpiece surface is smooth and smooth, and the quality is more uniform, which can effectively improve the appearance quality of the workpiece.
Wide applicability: Magnetic polishing machine can be used for different materials of the workpiece to remove welding spots, has a wide range of applicability.
Stainless steel polishing
It should be noted that the effect of magnetic polishing machine to remove welding spots is also affected by workpiece material, welding quality and other factors, it is necessary to choose the appropriate process parameters and polishing abrasives according to the actual situation.
