Abstract

This article deals with the use of the FMEA method process in welding processes with the aim to eliminate the causes of defects in welded joints. Welded products and their welds require an improvement in quality, both visual and structural. By increasing the quality of welded joints, we will achieve customer satisfaction and help to reduce costs in terms of the forced repairs of non-conforming pieces. Welding quality is based on the weld joint requirements. It is always based on the business contract, on the order, the relevant standards or technical conditions. The weld must be inspected and evaluated both on the surface and under the surface. Defects in welds are dangerous concentrators of tension that badly affect the limit of fatigue. The application of the process FMEA method aims to minimize defects in the welded joints and improve the resulting quality of the welded parts in the welded joints. To use this method properly, it is important to describe the welding processes, analyse the possibilities of defects and their consequences.
