Consumable Double - Electrode GMAW Part II : Monitoring
Consumable DE-GMAW is an innovative welding process, which can significantly increase the deposition rate without raising the base metal heat input to an undesired level. To be qualified as a practical manufacturing process, feedback control is required to assure the presence and stability of the bypass arc. To this end, the bypass arc voltage was selected to monitor the state of the bypass arc...
متن کاملSubmerged Arc Surfacing with a Multiple-wire Electrode
Surfacing is a technological procedure of applying a layer of filler material to a surface of another material, i.e. a product. By surfacing, it is possible to improve chemical, mechanical, and physical properties of the parent metal, and, consequently, those of the product surfaced. Surfacing may be applied to worn surfaces as well as to new products. A surfacing weld may have the same, simila...
متن کاملConsumable Double - Electrode GMAW Part I : The Process
Double-Electrode Gas Metal Arc Welding (DE-GMAW) is a novel welding process recently developed to increase welding productivity while maintaining the base metal heat input at a desired low level. In this paper, the DE-GMAW process was improved by replacing its non-consumable tungsten electrode with a consumable welding wire electrode resulting in a new process called consumable DE-GMAW. To unde...
متن کاملDouble-Electrode GMAW Process and Control
Double-Electrode Gas Metal Arc Welding, referred to as DE-GMAW, is a novel process which decouples the melting current into base metal current and bypass current by adding a bypass torch to a conventional GMAW system to establish a bypass arc. This makes it possible to increase the melting current while the base metal current still be controlled at a desired level. Experiments have been done to...
متن کاملElectrode Heating in a Wire-to-Plane Arc
A steady wire-to-plane electric discharge has been modeled in a prolate spheroidal coordinate system with the wire shape taken as a hyperboloid of revolution. A set of continuum conservation equations for the charged particle densities and temperatures together with Poisson’s equation for the self-consistent electric potential describe the steady electric discharge process. These equations have...
