Irradiation with a laser beam is performed along a welding bead, while the laser beam is aimed, as an irradiation point of the laser beam, at a contact point between a deck plate and a U-rib that is contained in a non-welded portion of a root part, from a side of the welding bead of the root part. Thereby, it is possible to remove a crack beginning at the non-welded portion of the root part generated at a joining portion between the deck plate and the U-rib of a steel floor slab, by the irradiation with the laser beam.

A user terminal device stores user information in a memory, and stores constant data in another memory. The user terminal device selects one or more other equipment to be combined suitably for use with the service equipment, based on the model information and operational conditions of the service equipment as well as the stored constant data. Then, the user terminal device transmits the user information and the selection information to the host computer, and requests display permission from the host computer for displaying the selection information onto the display section. The selection information is displayed on the display section only when the display permission is obtained from the host computer. Thus, workload on the host computer end may be reduced. In addition, the host computer does not fail to obtain the user information.
