Shot peening: a solution for fatigue failure or stress corrosion in welded joints

Welded joints are known to be the critical zones in mechanical parts. The problems arising in welded joints are specific in each industrial field. These problems are due to environmental and service conditions, the materials used for fabricating the joints, etc. Consequently, the question arises always: Which are the industrial methods for achieving a quality production Which are those allowing at a reasonable price to extend the service life Frequently, shot peening is the solution. On this account, both theoretical phenomena and some applications of this surface treatment are considered
