Welding roller can be divided into self-adjustable and adjustable roller racks. It can be applied to products of different sizes and diameters within the specified range. It can realize infinite speed regulation under the specified welding parameters, with low transmission noise and smooth working rotation. Among them, polyurethane roller can be used together. Polyurethane is a new organic polymer material, which has good oil resistance, toughness, wear resistance and aging resistance. Its tensile strength, tear strength and wear resistance are 3-5 times higher than those of ordinary rubber. The polyurethane wheel can be used without metal assistance. It is especially suitable for the welding of wind tower production line and stainless steel cylinder.
