The welding rod is a laminate structure in which a print layer is disposed between a first thermoplastic layer and a second transparent thermoplastic layer. Preferably the welding rod is in the form of an elongated element having a half-round cross-sectional shape. The welding rod is used to join two pieces of thermoplastic sheeting, particularly flooring, together. If the welding rod has a pattern similar to the printed pattern of the sheeting the resulting surface covering looks seamless.
