Low radial carriage welding head
The POLYCAR 51 LRC is an ultra-compact, open-type carriage welding head engineered for high-precision TIG welding of tubes and pipes. With a radial clearance requirement of only 2 inches, it provides exceptional accessibility in tight or confined environments where traditional welding heads cannot operate effectively.
The system integrates advanced automation features—such as Motorized Arc Voltage Control (AVC) and Torch Oscillation Control (OSC)—to deliver weld performance comparable to that of a skilled manual welder, but with greater consistency and repeatability. The POLYCAR 51 LRC is designed to excel in applications where space restrictions and high-quality results are critical.
Its compact design allows it to operate in areas that offer minimal room for tooling, and its lightweight construction enables the head to be mounted or removed in under one minute. Handling and adjustment are intentionally simplified, allowing operators to quickly prepare the head for use without extensive setup time.
Built to meet the highest TIG welding standards for all weldable materials, the POLYCAR 51 LRC is capable of reproducing all major movements of a manual welder, making it ideal for multi-pass welding applications. During operation, the head travels smoothly around the pipe using a pre-mounted guide ring, ensuring stable movement and uniform weld quality.
The system benefits from Polysoude’s more than fifty years of expertise in welding technology, resulting in a solution that delivers both flexibility and exceptional performance across a variety of industrial environments.
