“…At present, it has been found that the hot crack in stainless steel welding is mainly related to the alloy composition and the content of impurities [81]. Sulfur and phosphorous impurities, in particular, expand the solidification range by forming eutectic liquids with low melt-ing point [80,82,83]. The Hammar-Svensson chrome-nickel equivalent ratio (Creq/Nieq) during solidification also affects the crack sensitivity [84][85][86].…”

Electric vehicle battery systems are made up of a variety of different materials, each battery system contains hundreds of batteries. There are many parts that need to be connected in the battery system, and welding is often the most effective and reliable connection method. Laser welding has the advantages of non-contact, high energy density, accurate heat input control, and easy automation, which is considered to be the ideal choice for electric vehicle battery manufacturing. However, the metal materials used for the electrodes of the battery and the connectors used to connect the battery are not the same, so the different materials need to be welded together effectively. Welding different materials together is associated with various difficulties and challenges, as more intermetallic compounds are formed, some of which can affect the microstructure, electrical and thermal properties of the joint. Because the common material of the battery housing is steel and aluminum and other refractory metals, it will also face various problems. In this paper reviews, the challenges and the latest progress of laser welding between different materials of battery busbar and battery pole and between the same materials of battery housing are reviewed. The microstructure, metallographic defects and mechanical properties of the joint are discussed.

“…However, the welding of DSS S31803 is prone to welding cracks, heat-affected zone embrittlement, and the formation of pores. Solidification cracking is very common in the welding process of austenitic stainless steels and can lead to premature failures [4]. The Sigma phase is a deleterious phase that can be formed in duplex stainless steel during welding processes, leading to a decrease in mechanical properties and corrosion resistance [5].…”

Duplex stainless steel has been widely applied to industry. In this paper, nondestructive testing, chemical composition analysis, metallographic analysis, hardness test, and scanning electron microscope were used to study the causes of the crack in the butt joint girth weld of pipe and flange. Both steel pipe and flange are duplex stainless steel S31803. Through analysis, it was judged that the crack was a crystalline crack, generated in the welding process, which was related to the welding process and the control of the welding installation gap between the steel pipe and the flange with unequal wall thickness.
