“…Only a few researchers have looked into the major issue of AHSS grades during welding and reported degradation in the mechanical properties during welding. Denisa et al [132] compared the fatigue parameters of as-received material to the fatigue life of the GMAW joints of Domex 700 MC. The base material, Domex 700 MC, was tested for fatigue endurance in both as-received and welded conditions using the rotational bending Rotoflex testing instrument.…”

In recent years, the demand for advanced high-strength steel (AHSS) has increased to improve the durability and service life of steel structures. The development of these steels involves innovative processing technologies and steel alloy design concepts. Joining these steels is predominantly conducted by following fusion welding techniques, such as gas metal arc welding, tungsten inert gas welding, and laser welding. These fusion welding techniques often lead to a loss of mechanical properties due to the weld thermal cycles in the heat-affected zone (HAZ) and the deposited filler wire chemistry. This review paper elucidates the current studies on the state-of-the-art of weldability on AHSS, with ultimate strength levels above 800 MPa. The effects of alloy designs on the HAZ softening, microstructure evolution, and the mechanical properties of the weld joints corresponding to different welding techniques and filler wire chemistry are discussed. More specifically, the fusion welding techniques used for the welding of AHSS were summarized. This review article gives an insight into the issues while selecting a particular fusion welding technique for the welding of AHSS.

“…[7] Denisa et al examined the fatigue life of HSLA Domex 700 MC welded joints and proved the decrease of mechanical properties of welded specimens, especially in the HAZ. [8] In previous studies, the HSLA welded joint has been extensively studied to obtain excellent mechanical properties, but seldom research on its corrosion problems, especially for the welded joint used in many sectors such as oil and shipbuilding. The corrosion problems could decrease the mechanical properties of the welded joints, so corrosion occurring on welded joints must be considered for HSLA welded joints.…”

In this work, the corrosion behavior of high-strength low alloy (HSLA) steel welded joints in natural seawater solution was investigated by electrochemical and immersion tests. The experimental results prove that the corrosion resistance of the weld metal (WM) was higher than that of the base metal (BM). The scanning Kelvin probe results show that the potential distribution of the BM zone is lower than the heat-affected zone (HAZ) and WM zone. The scanning vibrating electrode technique results demonstrate that the initial attack for the HSLA welded joint majorly took place in the BM zone after immersion in natural seawater. The corrosion morphology of the HSLA welded joint after immersion was observed by scanning electron microscope. The corrosion morphology of BM and HAZ regions tends to be uniform corrosion, whereas it is mainly pitting corrosion for the WM zone.
