The basics of diving and working under water have been highlighted and explained as such, while these circumstances have also great influence on the welding behavior of the consumables applied. The challenge is in the execution of the welds and repairs. The paper covers the diving, welding and metallurgical aspects of underwater „wet” welding & cutting using covered electrodes based on industrial examples and applications for joining and repair welding. Shielded Metal Arc Welding (SMAW) and covered stick electrodes are a very versatile, flexible, simple and practical welding process, for this reason often used for underwater maintenance and repairs.

W artykule przedstawiono i wyjaśniono podstawy nurkowania i pracy spawacza w warunkach podwodnych. Wykonanie spoin i napraw w takich warunkach stanowi spore wyzwanie. Omówiono aspekty spawania i metalurgii podwodnego „mokrego” spawania i cięcia przy użyciu elektrod otulonych w oparciu o przykłady przemysłowe łączenia i spawania naprawczego. Spawanie elektrodami otulonymi (SMAW) jest wszechstronnym, elastycznym, prostym i praktycznym procesem spawania i z tego powodu często stosowanym przy konserwacji i naprawach pod wodą.
