The optimization of production processes in companies comes down to two main measures influencing the economic factor. The first one is the reduction of interval micro-periods between operations, and the second is to use post-production waste as much as possible. These treatments apply to virtually all industries regardless of the final product effect. This article describes the application of a special welding device for welding the workpiece with a bush type, designed for fixing the plate in the plate gun. As a result of its application, a significant reduction of time needed to produce one bush has been achieved, and thus the amount of time in a unit of time has been increased. As part of the implementation work, the bush design changes were also made, which made it possible to reduce post-production waste not suitable for current production, but allowing its use for other purposes. The results of the work were implemented in the company producing agricultural machinery in Lublin.
