Title:
WELDING METHOD UTILIZING ELECTRON BEAM ENERGY
Document Type and Number:
Japanese Patent JPS60223677
Kind Code:
A
Abstract:
By coating a workpiece with a uniform layer of polyimide containing surfactant upon the nonweld areas, spatter produced in electron beam welding of the workpiece is prevented from adhering to the workpiece surface in the nonweld areas.
