... portion of the weld adjacent to the low-carbon steel handle; fracture had occurred in this zone. Sufficient heat had been generated during welding to fuse an excessive amount of the carbon steel and thereby dilute the weld deposit locally to create a layer of low-alloy steel between the handle and the...
