The Encompass Gen II MIG Overlay System is a full function (vertical and horizontal travel, AHC, oscillation and wire) weld system designed for multi-pass GMAW welding. This weld system is designed for the automatic welding of plate surfaces in a box configuration of 9’ by 3’ in two (2) configurations, boiler and vessel modes. In boiler mode the system is designed to weld in a vertical application, oscillating horizontally across the weld bead. In vessel mode the system is designed to weld in a horizontal application, oscillating horizontally.
Mounting of the weld system is quickly accomplished via utilization of a box travel beam and rack system that can be mounted in both vertical and horizontally applications. The carriage, index beam and torch travel assemblies are modular in design and can be quickly installed on the travel beam. This arrangement allows quick and easy maintenance or adjustments of the assemblies without complete removal of the system.
An intelligent servomotor for the low torque end requirements, to traverse the carriage assembly quickly along the vertical beam, drives the vertical travel axis. This motor is a complete servo motion control system with integrated multi-axis motion control, amplifier and feedback controller. The oscillation, torch height, wire feed and horizontal travel axes of the weld system utilize DC high torque smart stepper motors with integrated motion controller and micro-stepping drive.
Both travel axes incorporate a two-speed travel jog system that allows for precise torch positioning as well as rapid traverse in order to position the carriage assembly quickly and precisely during both weld and setup modes.
The MOS utilizes a low voltage power supply that provides power for the mechanical system and distributed process control for multi-pass welding.
EMI also provides an optional “Cone and Dome” subsystem for the MOS when used for vessels cone or dome applications.
