Abstract
In producing a laminated white iron composite the white iron casting is bond ed to a mild steel backing plate through a brazing operation. The adjacent mating surface s of the casting and backing plate are secured together along with the copper brazing agent in such an orientation so as to promote an acceptable bond and to eliminate any shift from the desired orientation. The Domite Assembly Lip incorporates a recessed depression or pocket in the backing plate that follows the dimensions and shape of the casting creating a edge or lip that allows the copper brazing agent and the machined face of the casting to fit into the pocket created in the backing plate securing the assembled piec es together without the need of additional fastening methods such as wire or spot weldin g. The assembled parts can then be brazed.
Description
DOMITE ASSEMBLY LIP
DESCRIPTION
The manufacturing of a composite laminated white iron product consists of a machined ASTM A532 white iron casting (example casting shown on exhibit 1) bonded through a brazing procedure to a mild steel backing plate (example backing plate shown on exhibit 1). The process combines the exceptional wear resistant properties of the white iron with the ductility and flexibility of mild steel.
The lamination is achieved by affecting a metallurgical bond between the white iron casting and the mild steel using copper as the bonding agent. Traditionally the adjacent surfaces on both materials are surface machined to obtain a clean and tlat mating area. A
thin strip of copper cut to match the profile of the surfaces and is placed in-between the mating surfaces to create an assembled part.
Prior to brazing the two i~naterials it is necessary to secure the assembled parts in order to facilitate a complete bond and to eliminate the possibly of shift occurring during the brazing process which will result in the two mating surfaces misaligning from their originally desired orientation.
Assembled parts are secured together using various methods according to appropriate brazing techniques. "The most common method of securing the assembled parts is the use of baling wire. Other fastening methods can but are not limited to including strapping, banding and spot welding. All of these methods are time and resource consuming while not eliminating shift from occurring.
The Domite Assembly Lip was developed to eliminate the need to secure the assembled parts using the above mentioned techniques and also to eliminate the possibility of shift.
Exhibit 2 shows a typical assembly incorporating the Domite Assembly Lip.

Claims
When securing the assembled casting, copper and backing plate the Domite Assembly Lip utilizes a recessed depression integrated into the mild steel backing plate which incorporates a resulting raised edge or lip that parallels the dimensions and contours of the white iron casting. Exhibit 2 shows the assembled pieces fitting together.
The depression provides adequate depth and clearance to allow the copper brazing agent and the casting to sit securely into the depressed pocket on the mild steel without the need of additional fastening. Exhibit I shows detailed dimensions of the casting and backing plate.
The parts in claim 1 are not limited to the dimensions and shape of the Wear Buttons shown. The Wear Button showed on exhibit 1 and 2 demonstrate a typical part.
The Domite Assembly Lip can be used on any casting and backing plate assembly suitable for the lamination process.
The depression provides adequate depth and clearance to allow the copper brazing agent and the casting to sit securely into the depressed pocket on the mild steel without the need of additional fastening. Exhibit I shows detailed dimensions of the casting and backing plate.
The parts in claim 1 are not limited to the dimensions and shape of the Wear Buttons shown. The Wear Button showed on exhibit 1 and 2 demonstrate a typical part.
The Domite Assembly Lip can be used on any casting and backing plate assembly suitable for the lamination process.
