Special features of formation of defects in explosion welding of two-layer large plates

Abstract

Continuity check results of two-layer plates from several consignments are given. A shock pinched plasma generator and explosion welding technique on its base are developed, application of which allowed for excluding discontinuity formation at the beginning of welding and for eliminating stabilization area of joint efficiency and wave structure.

Keywords:

• explosion welding
• discontinuity flaw
• cumulation effect
• joint efficiency
