Robo Pipe Information

Pipe fabricators now have a versatile, easy to use,  cost effective, and highly productive pipe welding system; Robo Pipe.  It is an unmatched automated welding solution for the pipe industry with amazing welding procedure flexibility.  Robo Pipe brings shorter cycle times, excellent bead contour, reduced cleaning, root fusion, less grinding, and consistent weld quality.

Robo Pipe robot arm has the flexibility to adapt to welding fittings on Weldolet, Sockolet, Threadolet, Nipolet, Latrolet, Elbolet, and others, welding at around 80% of normal shop pipe production. 

This system uses the capabilities of Lincoln Electric's revolutionary Power Wave 455M/STT to create an industry-leading robotic welding system.  The Power Wave 455M/STT is ideal for the pipe welding industry as it is a proven inverter-based power source and comes loaded with technologies such as STT (Surface Tension Transfer) and Waveform Control Technology.  These allow open rood welds with STT and change on the fly to pulse spray GMAW (MIG) for the hot, fill, and cap passes.  This also helps to provide precise heat input control, minimal distortion, and reduce spatter characteristics.  All of this and more make the 455M/STT the premier choice for satisfying high duty cycle demands of robotic welding applications. 

The tolerances on joint prep include: Root Gap: 2-3 mm, Land Thickness: 0-2 mm, and Misalignment: 1/2 Root Gap. 

There are other options available to further improve Robo Pipe, including:

Manual Seam Tracking via "Joy Stick" Control and Through Arc Seam Tracking (TAST) allows an operator to move the robotic torch,  both vertically and horizontally, to keep the weld pool in line with the joint.  TAST can be enabled once the robot begins welding, after the root pass. The robot weaves across the weld joint and modifies its path based on any out-of-roundness or joint location shift. 

Adaptive Welding using Laser-Based Vision Tracking, also known as Joint Tracking, involves real time tracking just ahead of where the weld is being deposited.  This allows for not only robot trajectory shifts, but also adaptive control such as adjustments to voltage, wire feed, travel speed, or weaving to change weld bead deposition. 

It is important to note that the Robo Pipe workcell can accomplish Saddle welds and Miter welds on fittings, but it is not recommended for pipe to pipe connections due to robotic torch.

Overall, the strategic alliance of Lincoln Electric with FANUC produces an unparalleled combination of welding and robotics expertise with a single-source efficiency.  You cannot choose a better partner than these two, get started with your Robo Pipe workcell today!
