TANDEM AND MULTI-WIRE WELDING IN SHIPBUILDING AND LINE PIPE PRODUCTION

This paper which deals with submerged arc welding with two and three electrodes, the author has attempted to explain and expand upon the expression "heat input". Heat input determinations not only facilitate experimental and practical work on the development side of submerged-arc welding, but they can also with advantage be used for other processes, the welding characteristics and metallurgical properties of which are being investigated, e.g. manual metal-arc welding. As regards multi-wire welding, the electrical connection systems are of importance for the stability and practical functions of the welding process. A summary of experimental results and recommendations is given. The above aspects are illustrated by examples taken from shipbuilding and line pipe production.
