Whether welding together a few relatively simple parts or fabricating large, complex structures, weld fatigue is likely to be the most-common failure mode if the part or structure is subjected to fluctuating stresses.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/metals/fatigue-welded-steel-structures" target="_blank">read more</a></p> http://machinedesign.com/metals/fatigue-welded-steel-structures#comments Metals Mon, 03 Mar 2014 16:38:00 +0000 35151 at http://machinedesign.com Photochemical Machining http://machinedesign.com/metals/photochemical-machining <div class="field-deck"> Sponsored by Photofabrication Engineering Inc. </div> <div class="node-body article-body">What is photochemical machining?
