Integrated automatic voltage control (AVC) and oscillation control assembly for orbital welding applications

摘要

A weldhead assembly is disclosed. The weldhead assembly comprises a welding torch, an AVC subassembly mounted on an oscillation base adapted for movement back and forth across a weld joint, the AVC subassembly adapted for movement of the weldhead closer to and farther from a weld joint, and a motor adapted for driving the movement of the AVC subassembly, the motor mounted on the oscillation base.
