Dissimilar welds between unreinforced AA6082 and AA6092/SiC/25p composite by pulsed-MIG arc welding using unreinforced filler alloys (Al–5Mg and Al–5Si)

Corrosion Fatigue Behaviour of Aluminium 5083-H111 Welded Using Gas Metal Arc Welding Method

“…The limit values of the fatigue damage ration are zero (0) and one (1). The DR approaches zero only when N f NaCl approaches zero, i.e.…”

Meeting challenges in welding of aluminum alloys through pulse gas metal arc welding

“…Hot cracking can be reduced by selection of correct filler rod and reduction in the amount of heat input to weld [14,26]. As stated above, interfacial chemical reactions tend to have detrimental effect.…”

“…This can be achieved through reduction of heat input to the weld materials [14,26]. Selection of filler rod also influences the microstructure along fusion line in two ways: (1) complete inhibition of reactivity at fusion line as shown in Fig.…”

“…Observations at fusion line using different electrodes at reduced heat input to aluminum metal matrix composite (a) complete inhibition of reactivity at fusion line and (b) permissible level of wetability between SiC and molten pool[26].…”

Arc Brazing of Aluminium, Aluminium Matrix Composites and Stainless Steel in Dissimilar Joints

“…The matter becomes more pronounced, when the reinforcing particle phase comprise SiC that either thermally degrades or dissolves into the Al matrix, if the thermal load from the joining process is too high. Dissolving will result in brittle intermetallic Al 3 C 4 precipitates and a joint strength decrease of 50% [14,15]. Furthermore, the level and time of the heat input influence metallurgic processes at the interface between matrix and reinforcement phase and can lead to high porosity levels and chemical inhomogeneity in joining zones, if not adapted [16].…”
