SAW with multiple electrodes achieves high production rates
- Inst. Za Varilstvo, Ljubljana (Slovenia)
Increased demands for higher productivity in the production of welded structures dictate the use of new higher-performance welding procedures. Submerged arc welding (SAW) is already one of the highest performing arc welding processes, but with certain improved variants, its performance can be increased. These variants are multiple-head welding, double electrode welding and submerged arc welding with metal powder addition. These three variations of submerged arc welding have been put into practice and are extensively treated in the welding literature. The application of welding with more than three wires in a joint contact tube is rare, however, and rarely mentioned. The purpose of this article is to show the basic characteristics and eventual applications of SAW using multiple electrodes.
