This paper presents the results of measuring the temperature at the joint boundary and in the heat-affected zone using the developed computational and experimental methods based on the use of natural thermocouples. It is shown that in explosion welding of materials with developed wave formation at the joint boundary, the main heat release occurs in a narrow region limited by the size of the generated waves.

Cylindrical Waveguides

The possibility of obtaining multilayer cylindrical waveguides by explosion welding is investigated. The fact that the technological welding scheme has a significant impact on the shaping of workpieces and the value of edge effects was established. The studies demonstrated that the nature of wave formation during the manufacture of multilayer cylindrical waveguides from a homogeneous material by explosion welding using a central rod is identical to the wave formation when welding flat multilayer compositions on a rigid base.

The Waves

he structure, morphology, microhardness and ultimate detachment strength of a welded joint «brass L63—invar 36N» made by the explosion welding have been investigated. With the selected welding parameters and plate thickness (brass — 12 mm, invar — 8 mm), the shape of the joint boundary is wavy with stable parameters (amplitude and length). Cast inclusions of the composition CuZnFeNi with microhardness up to 500 HV were found in the troughs and on the crests of the waves. It was found out that microhardness of the heat-affected zone on the side of brass was by 50% higher than microhardness of the base material, on the side of invar — by 20% higher. Ultimate detachment strength of the joint is 550 MPa, that is higher than strength of the starting materials.

The paper presents the results of studies of interlayer boundaries of laminated metal materials with an inner protector during explosion welding. The calculation of the optimal parameters of explosion welding and their influence on wave formation in the interlayer boundaries is carried out. The structure formation of the transition zone of the interlayer boundary has been studied.
