Stress relieving is a common practice among manufacturing codes for reducing the magnitude of residual stresses in welded, quenched, and tempered steel structures and pressure vessels. The present work investigates the effect of stress relieving at 480, 560, 620, and 680°C on the microstructure and mechanical properties of 20 mm ASTM A517 Gr. B steel plate weldments produced by shielded metal a...

Underwater wet welding (UWW) is applied to repair basic offshore structures, underwater pipelines, water transportation, docks, and port equipment. The method used in the current research was shield metal arc (SMAW), this conducted on an A36 steel plate. We investigated effect of a temperature 10 ± 5 °C different types flow (without flow, non-uniform with baffle bulkhead, without bulkhead). def...

Underwater wet welding (UWW) combined with the shielded metal arc (SMAW) method has proven to be an effective way of permanently joining metals that can performed in water. This research was conducted determine effect water flow rate on physical and mechanical properties (tensile, hardness, toughness, bending effect) underwater welded bead A36 steel plate. The control variables used were a spee...
