A Tank Welding Machine is an automatic welding system specially designed for the fabrication of large cylindrical storage tanks, such as oil tanks, water tanks, and chemical containers. It automates the welding process along the vertical (longitudinal) and horizontal (circumferential) seams of tanks by using a track or magnetic crawler system. These machines are widely used in industries such as petrochemical, water treatment, energy, and food processing. By improving welding consistency, speed, and quality, tank welding machines significantly reduce labor costs and ensure higher structural reliability.
