The effect of different tungsten electrode tips to arc pressure under the controlling magnetic field condition in narrow-gap welding

摘要：

The problem of side-wall incomplete fusion in narrow-gap TIG welding could be well solved when the proper magnetic field was added. However, the various tungsten electrode tips seriously affect the distribution of arc pressure and the quality of welding seams. This paper studies the distribution of arc pressure of 5 different styles of tungsten electrode tips: 30 degree circular cone, 60 degree circular cone, 60 degree circular cone with truncated cone of 2mm diameter, terrace of 2mm*2mm, terrace of 2mm*0.8mm with the same welding parameters. The character of arc pressure is verified by assaying the seam cross-section under the controlling magnetic field condition in narrow-gap welding.
