Most industrial machines and assembled with welds and subjected to fluctuating loads over their lifetimes. This represents a challenge since welding inherently lowers the fatigue life of any structure. This issue can be addressed with proper fatigue improvement techniques for welds.
Most industrial machines and the structures that support them are subjected to fluctuating loads over their lifetimes.
The vast majority of these machines are assembled, at least in part, by welding, which means that their welded joints must sustain changing loads over their lifetimes. This represents one of the greatest challenges in designing for these conditions since welding inherently lowers the fatigue life of any structure.
This issue can be addressed with proper fatigue improvement techniques for welds, which this paper catalogs and assesses.
