Web– By cooling the cold water of the rollers. E.-Main functions of the welding pressure: 1.- Keep in contact the materials to be welded 2.- Prevents the arrival of air to the welding zone 3.- Forces the electric current to pass between the surfaces in contact 4.- Maintains a constant air contact resistance 5.- WebWelding rollers should be made of high-quality steel. If a base of welded construction is used, a stress relief heat treatment must be performed after welding. 8. The welding roller must be equipped with a reliable conductive device, and the welding current is not allowed to flow through the bearing of the welding roller. 9.
WebRoller seam welding is based on the same process principle as spot welding. The process has two main advantages when compared to spot welding: Roller seam welding is capable of producing a continuous seam. For many products, this impermeable seam is absolutely vital. In addition, it is possible to achieve faster cycle times than in spot welding. WebROLLER HS, this device is essential for supporting the pipes while they are being welded with the butt fusion machines. The rollers minimise pipe friction and drag force no matter which is the construction site condition. Special design for …
WebHot plate welding is possibly the simplest plastic joining technique, used for various applications ranging from small automotive fluid reservoir vessels to pipelines in excess of 1000mm in diameter. The technique involves heating the ends of the parts to be joined against an electrically heated platen until they are sufficiently molten.
