Light-weight structures produced by laser beam joining for future applications in automobile and aerospace industry

A layered cooling process in whole quenching process for lightweight front axle beam

“…Compared with Fig. 5(a) and (c), as part of section A is covered by spray cooling medium, the cooling rate of points A1 to A9 all become larger and the increment of cooling rate decreases with increment of 08004-p. 4 ICNFT 2015 the distance from surface. Compared with Fig.…”

“…During the using process, front axle beam is requested a proper strength and impact toughness because of the alternate-complicated stress on front axle beam, which also indicates a high technology requirement in thermal treatment. In order to realize the light-weight of front axle beam [3,4], the center zone has several holes. Figure 1 shows the photograph of the front axle beam.…”

Optimization of RSW parameters by joining galvanized steel HZ 220 BD-Z100 MB with aluminium AV 1050A

“…Welding methods in practice have been mainly applied by technologies using concentrated energy sources -laser beam [2][3][4], and to a limited extent also TIG and MIG arc welding technologies [3,5].…”

Influence of Si Coating on Interfacial Microstructure of Laser Joining of Titanium and Aluminium Alloys

“…Researches concerning the laser joining of titanium and aluminium alloys have shown that the thick intermetallic layer can be restricted only when the titanium alloy melts during the process. The high cooling rate inherent to laser processing decreases the interaction time between the melted aluminium alloy and the solid titanium alloy, promoting thinner intermetallic layers 12,13 . 16 .…”
