Claims
- 1. A glass coated article comprising a glass coated substrate, said substrate comprising at least two dissimilar metals and means for joining together said two dissimilar metals which substantially eliminates intermingling of said dissimilar metals, said dissimilar metals being joined by a weld joint adapted to prevent the cracking of the glass coating over a surface of said weld joint, said weld joint comprising:
- (a) a base metal element, of a given composition of metal, including a first flat plane smooth surface on one edge thereof, said first flat plane smooth surface extending across that full surface of said base metal element which is to be joined to a dissimilar metal;
- (b) a welding insert which is of a metal composition which is dissimilar to said base metal element, said welding insert including a second flat plane smooth surface on one edge thereof which is equivalent to said first flat plane smooth surface of said base metal element, said first flat plane smooth surface and said second flat plane smooth surface being welded together without substantial intermingling of said dissimilar metals of said welding insert and said base metal element, said welding insert including on its edge opposite from said second flat plane smooth surface, a first bevel adapted to form a first element of a v-shaped weld groove; and
- (c) a secondary metal element which is of a metal composition which is substantially identical to that of said welding insert, including a second bevel on one edge of said secondary metal element adapted to form a second element of said v-shaped weld groove, mated to said first element of said v-shaped weld groove, said v-shaped weld groove which is filled with welding filler metal to weld said first bevel to said second bevel.
