前言电子束焊接,现已成为一项人们所熟悉的焊接工艺,它分为低电压大电流的大功率或中功率焊接和高电压小电流的精密焊接。前者可以焊接几十毫米到几百毫米厚的钢板或各种不同形状的金属材料;后者可以焊接。.1毫米到几毫米厚的钢板或其
Foreword Electron beam welding, has now become a well-known welding process, which is divided into low-voltage high-current or medium-power high-power welding and welding high-voltage small current precision welding. The former can weld dozens of millimeters to hundreds of millimeters thick steel plate or a variety of different shapes of metal materials; the latter can be welded. .1 mm to a few millimeters thick steel or its
