Numerical study on the effect of thermal conduction on explosive welding interface

Explosive welding is an efficient method for metals welding. However, in explosive welding, the shock wave generated by the explosion can not only damage the sensitive structure in the area of the process, but also can actually destroy a welded joint immediately after its creation. By placing an additional structure (anvil) can reduce the influence of shock waves. The influence of different anvil on the explosive welding of aluminum and magnesium plates has been investigated by using AUTODYN Software in this paper. The results show that the steel anvil is much more appropriate than sand and magnesium.

. Literature provides three basic methods of explosive cladding, developed by Darenport and Person. Welding trials were performed in two- and three-layer arrangements, where in the second case, copper plates were welded with plates made from aluminium alloys with an interlayer of pure aluminium. Explosive welding technology does not always allow for joining of sheets of specific thicknesses. In order to obtain such thickness, they need to be rolled. The paper presents results of numerical study of asymmetrical rolling process of multilayer plates M1E-Al99.8-AlMg5. Numerical modeling of rolling of multilayer plates was realized by means of Forge 2D program that is based on finite element method. Obtained research results enabled to elucidate the process of rolling of multilayer plates.

Abstract In this work, TA2/T2 was used as a composite interlayer to prevent the formation of brittle Ti-Fe intermetallics when joining TC4 Ti alloy to 304 stainless steel. The TA2/T2 (commercially pure Ti and Cu) composite interlayer was prepared by explosive welding. The laser was focused on the TC4-TA2 interface, which joined the TC4 and TA2 by fusion welding. At the TC4-TA2 interface, a weld zone was formed due to the mixing of molten TC4 and TA2. The laser was also focused on the T2-304 stainless steel interface, a weld zone was formed due to the mixing of molten T2 and 304 stainless steel. Composite interlayer TA/T2 was used not only to prevent the formation of Ti-Fe intermetallics during welding but also to improve microstructure and properties of the stainless steel–Ti alloy joint. The joint fractured at the TA2/T2 explosive welding interface with a maximum tensile strength of 428 MPa.
