摘要： A method and apparatus includes a monitor in communication with, e.g., a work glove with built-in sensors to track an operator's physical activities including intermittently using hand tools, hand motion, and position or location in a work area. The sensors provide time-series data representative of the activities, and the monitor classifies and sequences the activities based on the time-series data along with, optionally, machine tool operational data. The classified and sequenced activities may then compared to instructed work procedures, ensuring correct work materials are used in production, and ensuring an operator's safety by detecting unsafe or abnormal work conditions.

摘要： An arc welding apparatus and corresponding method includes a torch, a non-consumable electrode and a consumable electrode both disposed within the torch, a wire feeder configured to feed the consumable electrode in a vicinity of the non-consumable electrode, a first power source and a second power source that provide independent current, respectively, to the non-consumable electrode and the consumable electrode, and a weld process controller to control outputs of the first power source and the second power source such that a concentrated arc is formed, as a heat source, between the non-consumable electrode and a workpiece, and an inter-electrode arc is formed between the consumable electrode and the non-consumable electrode to melt the consumable electrode. The approach is characterized by low heat input, low distortion, low spatter, and the relative high speed or high deposition of laser and laser-MIG hybrid and other forms of multi-wire/multi-electrode welding, cladding, and additive manufacturing.
