    diamondspark FCAW Portfolio for Pipeline Welding

    Our diamondspark seamless flux cored wires are the perfect combination with our welding equipment TERRA 400 PRM and pipeRunner® for orbital pipeline welding. Our seamless design allows a low content of diffusible hydrogen, no moisture pick up in storage and handling, consequently a low risk of hydrogen delayed cracking and wormholes. Our diamondspark X RC Pipe product range is copper coated with excellent current transfer and less contact tip wear.  Our flux cored wires are known for great feedability with increased arc time and no wire break.

    The special recipe optimized for pipeline welding also guarantees thick slag to support the welding pool in uphill progression and easy slag detachability. Pipeline dedicated formulas further improve the weld metal mechanical properties, maintaining high toughness also when applying high productivity welding procedures. diamondspark X RC Pipe is also suitable for sour service and is NACE compliant up to the X70 grade (in this latter case with diamondspark X70 RC-Pipe (N))
