Steel beams are usually fabricated to fit up to another beam. In order for the beams to fit perfectly, coping and slotting are required.
Coping or notching of beams is required to ensure that beams and columns fit without conflict (interference). It is often necessary to remove material from a flange or web in order for the intersecting steel pieces to fit.
To manually cope a steel beam, a layout man reads the detailed drawings and then transfers the dimensions of the cope to the steel beam, and uses a tape measure, framing square and chalk to draw the cope. Then using an oxy-fuel gas torch, an operator will manually cut out the cope from the steel beam. Often this rough cut requires considerable chipping and grinding in order to improve the appearance and finish of the cut.
There are several potential problems with manual beam coping:
