The All Position Overlay System is designed for pulp digesters, boiler tube walls or any vessel or surface that requires overlay repair. The system will travel at a regulated, precise travel speed producing consistent uniform overlay patterns. A welding current sensor monitors and controls the welding torch height on pitted or irregular surfaces. The system can be customized for job specific applications on circumferences or flat walls and can be configured to handle a variety of operating windows. The entire system is portable and can be broken down into small pieces for moving thru small manholes or openings.
