Improvement of S355G10+N steel weldability in water environment by Temper Bead Welding

Abstract

The normalized S355G10 + N steel was chosen for testing, it is used in a variety of applications including the building of offshore structures, which may require repairs in water environment. The main aim of the work was to check susceptibility to cold cracking for fillet welds – Controlled Thermal Severity (CTS) tests and butt welds – Tekken tests and in the next step evaluation of effectiveness of Temper Bead Welding (TBW) application in wet welding conditions for joints welded by covered electrodes. The TBW effectiveness was experimentally verified as a method that may reduce the susceptibility to cold cracking in water environment. An application of the TBW technique caused the maximum hardness of the heat affected zone to fulfill the criterion of EN ISO 15614-1 standard in level of 380 HV10. It was determined that for S355G10 + N steel the beneficial range of the pitch value between beads is 75%–100%.
