Study on Phenomena of Inert Gas Metal Arc Welding by High Speed Motion Pictures (Report 3)

Velocity and Acceleration of Transfering Droplet

Abstract

The overhead welding was experimented as well as the flat position welding. By the high speed motion pictures in this experiment, the following points were studied.
(1) Some peculiar characteristics of overhead welding.
(2) Velocity and acceleration of transfering droplet.
(3) Effects of current value, polarity, gas flow and gravity upon those in (2).
