爆炸焊接可焊性窗口下限药量试验研究

Experimented Study on Lower Limit Dynamite Amount of Explosive Welding Weldability Window

摘要: 在T10/Q235复合板的爆炸焊接试验中发现,成功爆炸焊接所需的实际最少药量比传统可焊性窗口下限动态参数确定的药量还减少了15%~20%左右,由此给出爆炸焊接药量系数修正式。依据修正式对3Cr13/Q235、1Cr18Ni9Ti/铸钢和62硬质黄铜/Q235复合板进行实际爆炸焊接生产检验,不仅大大减少了焊接药量和减轻了爆炸效应对环境的危害,而且复合板的焊接质量也完全满足工程的使用要求。因此,将修正式定义为对复合板爆炸焊接生产具有重要实际指导意义的"最佳焊接药量窗口"。

Abstract: It is discovered in explosive welding of T10/Q235 composite sheet that the practical least dynamite that needed for successful explosive welding has reduced 15~20% than ones assured by dynamical parameter of tradition weldability window.So the modifying formula of explosive welding dynamite is given.According to calculating dynamite of the formula,it has not only been cutting down the welding dynamite and minishing environmental harm of explosive effect,but the demand of welding quality needed in engineering use can be satisfied,through production examining of explosive welding for composite sheet of 3Cr13/Q235 and 1Cr18Ni9Ti/cast steel and hardness 62 brass/Q235.So the modifying formula is defined as "the best welding window of dynamite amount" that has important significance for guiding explosive welding production of composite sheet
