High Efficiency Longitudinal Seam Welding Machine, Outside Pipe Seam Welding

        High quality, productive longitudinal seam welding requires mature, superior technology. This is the only way we can protect and further our own position on the market in the face of increasingly fierce competition. Our Friendship Machinery^® longitudinal seam welders provide unbeatable technology for welding of longitudinal seams on metallic materials.

        We'll be happy to make some welding specimens for you (please state size and welding method) and then work out an Friendship Machinery ^® machine concept for your particular application case.
