PROBLEM TO BE SOLVED: To provide an execution method of a thermoplastic resin floor tile for a welding joining using no pressure sensitive adhesive, capable of preventing penetration of a stain into a tile and a joint and penetration of a maintenance agent, and capable of preventing unevenness of the tile. SOLUTION: This thermoplastic resin floor tile has the one edge length of 450 to 1,000 mm, and the thickness of 3 to 10 mm. This execution method of the floor tile is characterized in that the thermoplastic resin floor tile for the welding joining characterized by having a chamfered joint part having a width of 1 to 2 mm in a surface side edge part, and the depth of 1 to 3 mm is laid without using the pressure sensitive adhesive on a backing, the joint part of the thermoplastic resin floor tile for the welding joining is welded by thermal welding using a thermoplastic resin welding rod, an extra-fill of a welded part is shaven off, and is formed as a block integrated with a plurality of floor tiles, and this block is placed on the backing.
