Abstract:
A method for hardfacing a metal workpiece to provide a hardfaced work surface varying in composition over a cross section of the face thereof said method utilizing consumable guide nozzles and electroslag welding procedures.
Abstract:
A lip for an excavating bucket has a row of sockets in each of which a respective excavating tooth is mounted, the center of the lip being relieved (i.e., offset with respect to the corners thereof) in two mutually perpendicular planes, such that the corner teeth do the initial excavating without interference from the center teeth, in both forward and lateral movements of the bucket. The combination of the shorter teeth used in the center of the lip plus the relief mentioned causes the corner teeth to engage the working face in advance of the other teeth, in both forward and lateral bucket movements.
Abstract:
