Atgervi has a wealth of experience in robotic welding, spanning subassemblies on industrial scrubbers, pipe welding in the oil and gas sector, and tanker trailers. Our expertise shines in the automated welding segment where we excel in addressing a variety of needs.

Here are some examples of robotic welding systems:

• H frame weld cells

• Ferris wheel cells

• Dual headstock pipe welders

• Track-mounted robots for large assemblies

Let me elaborate on one of our featured robotic implementations: a system utilizing a Fanuc M710 12L robot mounted on a raised platform on a 60-foot track specifically designed for welding semi tanker trailer barrels.

In this system, the operator provides input such as barrel diameter, tank length, and the number of support rings. The robot then proceeds to the selected side and verifies the starting ring location. Using a seam tracker, the robot follows the first side of the ring, fully welding the circumference of the barrel. After completing one side, it transitions to the next, continuing until the ring is completely welded. The robot will then use a laser measuring device to find the next ring on the tank. The beauty of this process is it does not matter where the rings are placed as the robot can adapt to any variability in the spacing of the rings. The robot will repeat this process of finding a ring and welding it until the barrel is complete.

Additionally, the system is capable of welding heat channels for tankers used in transporting temperature-controlled products like asphalt. After loading the barrel and inputting parameters, the robot locates the first channel and performs continuous welding along its entire length. Once the first half is completed, the robot rotates the barrel to weld the other side of the channel and repeats the process back along the channel. This back and fourth is repeated until all channels are welded.

This system operates efficiently, with the ability to weld rings at 40 inches per minute (IPM) and heat channels at 60 IPM. Previously the barrels took two welders two full days to weld the heat channel and rings. The robot can weld 3 channels in 45 minutes and 12 rings in 2 hours. This allows for much greater throughput and a significant reduction in welding wire consumption due to bead size consistency. Welds are also stronger due to the continuous welding capability and consistent seam placement. The seam tracking feature allows the robot to adapt to the barrel's deformation caused by the welding process, ensuring precise and consistent welds throughout the manufacturing process.
