Seam Welding

In seam welding, current and compressive force are transmitted to the parts through disc-shaped electrodes. This method allows for the welding of lap joints, upset joints (the weld nugget is upset after welding), flanged seams, and stitched seams with foils. Depending on the rotational speed of the electrodes and the delivery method of the current, intermittent or leak-tight weld seams can be obtained. Rotary electrode discs are used in this type of welding. This process is commonly used in the fabrication of metal components such as pipes, tanks, and automobile bodies.

Seam welding discs are typically made from materials such as copper, brass, or other heat-resistant materials capable of withstanding the high temperatures generated during the welding process. These discs are designed to continuously rotate, applying pressure and heat to continuously create a strong weld seam on overlapping metal sheets. Welding discs come in various sizes and shapes, depending on the application and the thickness of the metal sheets being welded. Some discs are designed for use on flat surfaces, while others are designed for welding on curved or irregular surfaces.

Seam welding discs are widely used in industries such as automotive, aviation, and manufacturing where high-quality and durable welds are required. They are often used in conjunction with automatic welding machines that can control the speed and pressure of the welding process to provide consistent and accurate welds.
