The FCAW (flux-cored arc welding) process is performed with a continuous hollow electrode filled with a flux which provides shielding gases, deoxidisers, alloy additions and slag formers. The objective of this research was to analyse the mechanical properties of the heat-affected zone (HAZ) of different steel grades welded with FCAW. Cross-weld tensile test results show that no softening of the heat-affected zone occurs. The rupture always took place in the base material with one exception where rupture was initiated in the weld metal deposit by slag inclusion. Results confirm that the FCAW process perfectly suits the requirements for welding QST material from 355 to 500 MPa yield strength even for low-temperature applications.
