Titanium Welding Technology

In order to establish titanium welding technology TIG arc weldability and MIG arc weldability were surveyed. For TIG arc weldability influence of arc length and thickness to proper region of welding condition became obvious. For MIG arc weldability a new method to defend wandering phenomenon was developed.

Trends of Research Activities on Welding Process in Japan

This paper gives a recent progress of welding process research in Japan, especially, an instance in the capability of the visualization and prediction of welding arcs, though the dynamic observations of spectral image by a high-speed digital video-camera with a monochromator and also the calculations by numerical models. The dynamic observations lead to visualizations of metal vapor behavior in...

Comparison of Welding Processes and Control Technology Options for Clad Welding Machines

Overlay welding of nickel alloys for corrosive and sour service is commercially accomplished with most welding processes ranging from shielded metal arc (stick) to laser. The valve industry has generally standardized on hot wire gas tungsten arc (GTA-HW), pulsed gas metal arc (GMA-P) and submerged arc (SAW) welding. This document will focus on these three but a little history will help explain ...
