Properties of thermo-meclianically treated welds of high yield-point steel

摘要

The article presents the properties of thermo-mechanically treated welds of steel S700 MC with a thickness of 10 mm, created using various welding methods and with different values of supplied linear welding energy. The metallographic evaluation, tensile strength testing and hardness measurements allowed us to assess the structure and properties of the welds and evaluate the influence of the amount of heat supplied to the welding area on the tensile strength, impact strength and hardness of welds.
