New head and controls for submerged arc welding

to three wire feeders for single, tandem or triple arc operation. A new integrated control sys- tem allows all parts of the operation to be controlled from a single location. The sys- tem can be used for simultaneous control of ID and OD weld heads for spiral pipe welding from a single operator station. The new system includes weld control and is based on a network architecture, allowing it to be used with welding power sources from leading manufacturers. According to Bob Beattie of OSL, “Over the last 25 years we

OXFORD Sensors Ltd (OSL) has released a new, fully integrated system for tandem or triple submerged arc welding, with particular applications on spiral pipe mills. The new system incorporates several innovations. The completely new weld head design is easy to set up and adjust, and integrates up to three torches togeth- er with flux delivery and recovery, video camera and laser seam tracking. The system has a modular design for ease of using the key components in different applications. The new head has already been installed on several pipe mill loca- tions. For spiral pipe offline ID welding, it can be mounted on a new OSL compact boom-end frame incorporating fully inte- grated horizontal and vertical slides with space for up to three wire feeders. For spiral pipe OD welding or similar applica- tions, the new head can be mounted on an OSL slide assembly together with up
