Microstructure and fatigue properties of Mg-to-steel dissimilar resistance spot welds

Fatigue behaviour of dissimilar Al 5052 and Mg AZ31 resistance spot welds with Sn‐coated steel interlayer

“…Figures d and d show ductile fracture in the final rupture region. Similar observations were made at the fatigue fracture surface of Mg/Mg joint …”

“…A few published works are available on fatigue of magnesium dissimilar joints. Liu et al 35 compared the fatigue strength of Mg/steel spot-welded joints with that of Mg/Mg similar joints. The results show that the Mg/steel and the Mg/Mg spot welds have similar fatigue performance.…”

Interfacial Characterization of Dissimilar Joints Between Al/Mg/Al-Trilayered Clad Sheet to High-Strength Low-Alloy Steel

“…Fusion welding, such as laser welding, electron beam welding, and resistance spot welding, and solid-state welding, such as ultrasonic spot welding (USW), friction-stir spot welding (FSSW), and diffusion bonding, have been attempted to join dissimilar materials (e.g., Mg and Ó 2015 The Minerals, Metals & Materials Society steel). [19][20][21][22][23][24] USW has been identified as an emerging solid-state joining technique because of its low energy consumption coupled with a short welding time. 25 A big concern in such dissimilar metal joints, especially Mg-to-steel joints, is the galvanic corrosion because of the direct Mg-to-steel contact.…”

Joining of AZ31 Magnesium Alloy and Steel Sheet under Four Different Coating Conditions Based on Gas Metal Arc Weld-Brazing

“…Fusion welding processes have been used in order to overcome the disadvantage of solid-state welding between magnesium alloys and steel; these processes include a laser hybrid [9][10][11][12][13][14][15][16][17][18][19][20][21] , laser braze [22][23][24][25][26][27][28] , and resistance spot welding [29][30][31] on the dissimilar joint. Liu [9][10][11][12][13][14][15] and Qi [16][17][18][19] have applied a laser-arc hybrid process to various dissimilar joints of magnesium alloy and steel.…”

“…The joining mechanism was explained on the basis of braze welding, solid-state bonding, and soldering. In another study, the mechanical properties and fracture behavior of Mg-to-steel dissimilar resistance spot welds were determined and compared with those of Mg/Mg welds 31) . Recently, Cao 32) determined the feasibility of cold metal transfer (CMT) welding of AZ31 to galvanized mild steel lap joints.…”
