Abstract
A method of gas shielded arc welding steel railroad rails spaced from each other to define a transverse gap, which method comprising the steps of providing an elongated steel barrier plate wedged into said gap at the bottom of the spaced rails and filling gap above said steel barrier plate with a molten steel from an advancing filler metal electrode by a gas shielded electric arc welding process initiated by an arc between the electrode and the barrier plate.
Claims32
A method of gas shielded arc welding steel railroad rails each having a lower base with a support bottom having a given width, a vertically extending web and an upper wheel engaging head, said rails being spaced from each other to define a transverse gap to be filled with steel to join said rails wherein said gap has a lower opening, lateral, vertically extending distal openings and a selected width, said method comprising the steps of:
- (a) providing an elongated steel barrier plate with a length corresponding to said given width of said lower bases, a width greater than said selected width of said gap and a nominal thickness;
- (b) wedging said barrier plate into said gap at the bottom of said bases of said spaced rails;
- and,
- (c) filling said gap above said steel barrier plate with a molten steel from an advancing filler metal electrode by a gas shielded electric arc welding process initiated by an arc between said electrode and said barrier plate.
A system of gas shielded arc welding steel railroad rails each having a lower base with a support bottom having a given width, a vertically extending web and an upper wheel engaging head, said system comprising means for holding said rails spaced from each other to define a transverse gap to be filled with steel to join said rails wherein said gap has a lower opening, lateral, vertically extending distal openings and a selected width;
- an elongated steel barrier plate with a length corresponding to said given width of said lower bases, a width greater than said selected width of said gap and a nominal thickness, said barrier plate being located at the bottom of said bases of said spaced rails to close said lower opening;
- and welding means for filling said gap above said iron barrier plate with a molten steel, said welding means including an advancing filler metal electrode.
