Abstract

A system for butt welding expansion joint rails with an electroslag welding system. The electroslag welding system for butt welding the expansion joint rails comprises a control system. The method for butt welding the two expansion joint rails with the electroslag welding system comprises defining a weld cavity with a first expansion joint rail, a second expansion joint rail, a plurality of gland shoes, and a pair of butt shoes. The electroslag welding system can also be adapted to weld a expansion joint rail to a support beam. The method for welding the expansion joint rail to the support beam comprising placing the expansion joint rail on a horizontal axis, placing the support beam on a vertical axis and clamping a modular component system to the expansion joint rail.

Claims (16)

1. A system for butt welding two expansion joint rails with a control system, wherein each expansion joint rail comprises at least one gland cavity having a fixed distance from the top of each expansion joint rail, said system having a welding shoe assembly comprising:

a top gland shoe and a bottom gland shoe configured to occupy said at least one gland cavity; and

a pair of butt shoes that abut said expansion joint rail and said top gland shoe and said bottom gland shoe.

2. The system of claim 1 wherein said top gland shoe and said bottom gland shoe are composed primarily of copper.

3. The system of claim 2 wherein said plurality of butt shoes are composed primarily of copper.

4. The system of claim 1 wherein said top gland shoe and said bottom gland shoe are beveled.

5. The system of claim 1 wherein said top gland shoe and said bottom gland shoe slidably interface with one another.

6. The system of claim 1 wherein said top gland shoe and said bottom gland shoe are water cooled.

7. A welding shoe assembly for butt welding two expansion joint rails wherein each expansion joint rail comprises at least one gland cavity having a fixed distance from the top of each expansion joint rail, said welding shoe assembly, comprising:

a top gland shoe and a bottom gland shoe configured to occupy said at least one gland cavity; and

a pair of butt shoes that abut said expansion joint rail and said at least one gland shoe.

8. The welding shoe assembly of claim 7 wherein said top gland shoe and said bottom gland shoe are composed primarily of copper.

9. The welding shoe assembly of claim 8 wherein said plurality of butt shoes are composed primarily of copper.

10. The welding shoe assembly of claim 7 wherein said top gland shoe and said bottom gland shoe are beveled.

11. The welding shoe assembly of claim 7 wherein said top gland shoe and said bottom gland shoe slidably interface with one another.

12. The welding shoe assembly of claim 7 wherein said top gland shoe and said bottom gland shoe are water cooled.
