PARAMETER STUDY OF ELECTRON-BEAM WELDING

BEAD ON PLATE WELDMENTS WERE MADE ON A 2-IN THICK HY-130 STEEL PLATE TO DETERMINE THE EFFECTS OF WORK DISTANCE, BEAM FOCUS, ACCELERATING VOLTAGE, BEAM CURRENT, TRAVEL SPEED, TRAVEL DIRECTION, AND PREHEAT TEMPERATURE ON PENETRATION, WELD GEOMETRY, AND SOUNDNESS. THE RESULTS SHOWED THAT SOUND WELDS OF ANY PENETRATION UP TO 2 IN. COULD BE PRODUCED BY SELECTING THE PROPER COMBINATIONS OF PROCESS PARAMETERS. THE IMPORTANCE OF THE FOCAL POINT OF THE BEAM RELATIVE TO THE PLATE SURFACE WAS SHOWN, AND A METHOD OF FOCUSING THE BEAM AT HIGH BEAM POWER WAS DEVELOPED. /AUTHOR/
