用于超细颗粒焊剂约束电弧超窄间隙焊接的焊枪设计
Welding torch used in Ultra-narrow gap welding with Ultra-fine granular flux constricting arc and its design
摘要
Abstract
To solve the problems of Ultra-narrow Gap Welding with Ultra-fine Granular Flux Constricting Arc.A kind of welding torch is designed in this paper.The problems which conclude feeding wire accurately and adjustment of clamping force,the conduct of wire and flat contact tube and the anti-contact of flat contact tube with sidewalls and so on.While welding,wire is driven by the wire wheel through the guide wire tube into circular slot between the two flat contact tube and clamped by elastic clamping force,then being sent to ultra-narrow gap and being welded.The results show that the welding torch can meet the requirements of Ultra-narrow Gap Welding with Ultra-fine Granular Flux Constricting Arc,and a good weld is obtained.关键词
