摘要

研究了不同装药厚度对异种金属爆炸焊接质量的影响。在爆炸焊接过程中应遵循下限规律。对不锈钢(410S)和钢(Q345R)在15、25、35 mm三种不同装药厚度下进行了焊接实验。对三种试样的界面形貌和力学性能进行了观察和测试。结果表明:在电荷厚度为15 mm时,主要形成微、小波状结合,其强度最高,界面变形小,缺陷少;电荷厚度为25 mm时主要形成小、中波键合,强度较一般;电荷厚度为35 mm时,主要形成大波状键合,强度最低。通过电子探针微分析仪(EPMA)对三种样品的测试结果,分析并验证了微、小波浪形界面高结合强度的原因。

Lower limit law of welding windows for explosive welding of dissimilar metals

The influence of explosive charge thickness on the quality of explosive welding of dissimilar metals was investigated. The lower limit law should be followed in the course of explosive welding. Three welding experiments of stainless steel (410S) and steel (Q345R) were carried out in three different kinds of explosive charge thicknesses, namely 15, 25 and 35 mm. Interfaces of morphology and mechanical properties of three samples were observed and tested. It was found that micro and small wavy bonding is mainly formed for charge thickness of 15 mm whose strength is the highest with minor deformation and few defects in the interface; small and middle wavy bonding are mainly formed for charge thickness of 25 mm whose strength is comparatively mediocre; big wavy bonding is mainly formed for charge thickness of 35 mm whose strength is the lowest. The cause of high bonding strength of the micro and small wavy interface was analyzed and verified on the basis of the results of Electron Probe Micro-Analyzer (EPMA) tests of three selected samples.
