摘要: Carbide inserts in earth boring drilling tools are attached to the tool base metal by means of one or more spike welds formed by electron beam welding. The spike weld is formed at an angle through the metal surrounding the base of the insert and into the side of the insert near its inserted end.

摘要: Process for the production of bonded hard alloys, which comprises inserting a thin sheet of a Fe group metal or its alloy as a filler in between the surfaces of at least one kind of hard alloy, and applying a high energy beam to a part or all of the thin sheet to melt and solidify the thin sheet in a slit form, thereby bonding the hard alloys together.

摘要: A welding apparatus for welding hard segments to the circumference of a base of a saw blade. The blade base is clamped between two electrodes of a first electrode unit which can rotate. The segment is clamped by conductive fingers of a second electrode unit which is movable toward the first electrode unit. A power clamp presses together the conductive fingers together. The second electrode unit can rock to uniformly press the segment against the circumference of the blade base.
摘要翻译: 一种焊接装置,用于将硬段焊接到锯片的基部的圆周上。 刀片基座夹在可旋转的第一电极单元的两个电极之间。 该段由可朝向第一电极单元移动的第二电极单元的导电指夹紧。 电动夹将导电手指压在一起。 第二电极单元可以摇动以将片段均匀地按压在叶片基部的圆周上。
