Advances in Materials Science and Engineering - Hindawi

In this work, the weld metal (WM) for the Q690 high-strength low-alloy (HSLA) steel was prepared through flux-cored arc welding (FCAW) at 10 kJ/cm and 20 kJ/cm heat inputs. The effect of welding heat input on the relationship between the microstructural factors and the electrochemical behavior of the FCAW Q690 steel was studied.

TANDEM and GMAW Twin Wire Welding of Q690 Steel …

Abstract. Compared with using semi-automatic gas shielded arc welding, using automatic TANDEM twin wire welding and twin wire gas metal arc welding (GMAW) to weld Q690 steel, a low-alloy high-strength structural steel used in the hydraulic support in the fully-mechanized mining face, the welding speed, deposition rate, production environment and welding quality can be obviously improved.

Corrosion Behavior of Welded Joint of Q690 with CMT Twin

Q690 steel is known as a typical low carbon bainite steel with excellent mechanical properties, and it is widely used in offshore engineering industry [1, 2]. However, the complex chloride environment tends to be invalidated ahead of lifetime in welded parts, so it is significant to study the corrosion behavior of welded parts [ 3 , 4 ].
