The Wegener International Inner Rotary Welding System IWS has been designed to weld joints in concrete pipe protectors or pipe inliner segments. The system is a novelty when it comes to the quality and efficiency of welding. Depending on the application, the pipes or inliner segments can be joined either directly with an extruder V-seam or alternatively by means of an applied film strip. The IWS is lowered fully assembled into the pipeline and can be moved from joint to joint. The energy (electricity + compressed air) can either be supplied by trailing or pushing means. The system is expanded to the pipe wall around the pipe cross-section at the weld joint. The process head, which is mounted on a speed-controlled carousel and bears one or two EXWELD sigma SC extruders, is guided along the circumference of the pipe and the pipe segments are bonded together. The only work that has to be performed by the operator is to prepare and finish the seam as usual, and possibly insert the film and position the extruder at the start of work.The welding process is then performed automatically.

Further basic data for the system:
	Manual positioning in the pipe
	Can be operated on construction sites with protection against the weather
	Easy operation
	Service and maintenance work must be able to be carried out by trained personnel
	Control system: Siemens logo, mobile control cabinet, manual pressure reducer, pressure manometer and control elements
	Integrated reelstand for welding wire, mechanical, pneumatic clamping fixture for the preform
	Process forces are applied pneumatically
