Abstract

PURPOSE: To inexpensively and easily repair studs, by grinding the end of a burnt stud so that it has a flat head, and by instantaneously depositing a new stud on the flat head.
CONSTITUTION: A stud 2 of boiler tube 1 is burnt and the end becomes round. The burnt stud 2 is ground by means of a grinder, etc., and the end of burnt srud 2 is finished to have a lat head. Then, a new stud 3 having a prescribed length is forcedly placed on the flat head of the burnt stud 2, and a strong welding electric current is supplied through a welding electrode 5 of a condenser type welding machine. In this way, the studs 2 and 3 are instantaneously welded and no thermal stress strain will be generated in th boiler tube 1. After this depositing is completed, a refractory material 4 is driven into the stud space of the boiler tube 1. Therefore, renewal of the boiler tube itself is not required and the repairing cost becomes less.
