pipeRunner® - The Revolutionary Orbital Welding System

Pipeline construction and pipework welding are typical site operations. It is all about girth welds pipe-to-pipe. Today we want to show the potential of productivity improvements in welding high corrosion resistant alloyed pipes using stainless steel and nickel alloy 625 for orbital welding of pipelines.

When it comes to welding stainless or nickel alloy pipes, we recommend welding the root and hot pass with suitable high-alloy TIG rods and then the fill and cap layers with our FOXcore high-alloy flux cored wire range in conjunction with our pipeRunner® to boost your productivity and achieve the best quality.

Perfect weld results when welding a Clad 625 X 65 pipe grade with our UTP A 6222Mo-3 Tig rod with a diameter of 2.4 mm for the root and the hot pass, followed by m-GSFCAW mechanized gas-shielded flux cored wires FOXcore 625-T1 of 1.2 mm for the fill and cap layers, welded with our pipeRunner® in uphill progression.

The Perfect Weld seam can also be achieved with our stainless steel girth weld solution. In this case, a 304L  pipe welding was welded with Thermanit JE-308 L TIG rod of 2.4 mm for the root and the hot pass, followed by FOXcore 308L-T1 for the fill and cap layers, which were welded in uphill progression with the pipeRunner®.

In both cases, the best quality was achieved: perfect bead shape, very good slag removal, no risk of lack of fusion and porosity.
