Abstract

For the building of ships, bridges, and other welded structures where welding equipment must be transported to the site, it is desirable from the standpoint of increased work efficiency to decrease the weight and size of the equipment to be thus transported. Accordingly, a lightweight, compact, high frequency oscillation device with an electromagnetic force have been developed. This work discusses the capabilities of the new oscillation method that has been developed, and offers consideration of its application to the actual bead formation phenomenon in GMAW process. The results can be summarized as follows:<BR>1) The oscillating path of the current method stops at both oscillation terminals, and is characterized by high speed movement of 400 mm/sec. Maximum oscillation frequency is 40 Hz.<BR>2) Arc heat and force can be dispersed in GMAW process with the current method, such that the penetration depth can be limited and the bead width expanded.<BR>3) In addition, an flat bead surface can be obtained in horizontal fillet welding, where problems of overlap and undercut are prevented.
