Experimental investigation of explosion-welded CP-Ti/Q345 bimetallic sheet filled with Cu/V based flux-cored wire

Joining of CP-Ti/Q345 sheets by Cu-based filler metal and effect on interface

“…Their chemical compositions are given in Table 1. The explosive welding parameters were consistent with our prior study (Chu et al, 2015). UT (ultrasonic testing) was carried out for the bimetallic sheets.…”

“…The reliable bonding of CP-Ti/Q345 bimetallic sheets is the crucial factor for the industrial applications. Recently, Cu-V based fluxcored wire was applied as intermediate to join explosion-bonded CP-Ti/Q345 bimetallic sheet with TIG welding method in our publication (Chu et al, 2015). Results revealed that Cu-V based filler metal exhibited great prospects in fusion welding of CP-Ti/Q345 bimetallic sheet.…”

“…Argon gas with the purity of 99.999% was used as a shielding gas with total flow of 15 L/min. The groove dimensions of the CP-Ti/Q345 bimetallic sheet were machined as that applied in our previous study (Chu et al, 2015). The water cooling system was designed and the schematic diagram is displayed in Fig.…”

Microstructural, Mechanical and Corrosion Investigations of Ship Steel-Aluminum Bimetal Composites Produced by Explosive Welding

“…The increase in the bonding surface field results in the development of bonding interface strength. It has been noted in the literature [20][21][22] that a wavy bonding interface is usually desirable in explosive welding, since it ensures a larger bonding interface field as well as greater bonding strength. Moreover, small peninsular and island-shaped ship steel sections can be observed on the aluminum side of the bonding interface.…”

Interface Characteristic of Explosive-Welded and Hot-Rolled TA1/X65 Bimetallic Plate

“…Bimetallic sheets in which TA1 is used as the material of the flyer plate instead of steel can greatly improve the life of the refining equipment and pipeline. In recent years, researchers have conducted many studies on the microstructure and mechanical properties [26][27][28][29][30][31][32][33][34][35], heat treatment [36][37][38], hot rolling process [39], residual stress [40], bonding mechanism [41][42][43] and butt welding process [44,45] of explosive bonded Ti/Steel bimetallic sheets. These work mainly focused on the bimetallic sheet itself, while investigation regarding the suitability of explosive bonded Ti/Steel bimetallic sheet for the subsequent process, such as the JCOE process (progressive forming process of 'J' forming, 'C' forming and 'O' forming, reducing gap, welding and mechanical expanding), was rather limited.…”
