Abstract

The paper presents the factors that affect weldability, with special reference to the weldability of micro-alloyed and quenched and tempered steel. Tests were carried out by simulating the weld thermal cycle simulator type Smitweld TCS 1405, and methods of Implant and Tekken for the purpose of determining the propensity of micro-alloyed and quenched and tempered steel cold cracking. At the end of the proposed welding parameters which assume welding connection without cold cracks.

Keywords

weldability; cold cracks; implant method; Tekken method; fine grain structural steel; steels for structural improvement quenching
