摘要： An exemplary welding nozzle has a smooth, highly polished bore of circular cross-section. The bore has a forward portion of generally flared, gradually curving shape, joined with a narrowing inner portion along a gradual curve. Hence a concentrated surface flow of shielding gas may be directed out the nozzle's mouth to reliably provide a flared shielding envelope having reinforced boundaries. The inner portion tapers inwardly at a constant angle for a length sufficient to dampen flow disturbances. Hence an inner core of shielding gas of high ionization potential may be directed in laminar flow out the nozzle's mouth for concentration immediately about the exposed electrode to stabilize the electric arc at the electrode tip. The diverging gas flows enable significantly reduced gas consumption while reliably maintaining weld quality, a reduced rate of spatter buildup within the nozzle, and increased versatility of welding tip operation in both automated and manual environments.
