eFatigue - International Institute of Welding

Weld class 160,for steel,represents unwelded structural steel plate.A welded structure may not have greater fatigue resistance than an unwelded plate so this represents an upper bound on the fatigue behaviour.The curves are straight lines,on a log-log scale.What is Steel Fatigue Failure? Associated Steel CorporationWhat can we do to minimize fatigue type failures? First and foremost,make sure you are working with high quality materials.In the case of steel,make sure it has a high degree of cleanliness,free of internal defects.There are methods of steel production that insure your steel has excellent core integrity.What is Fatigue in Welded Steel?Fatigue causes over 90 percent of failures in engineering components with welded steel parts.Fatigues on stationary equipment is a huge concern,however,it is crucial in mobile equipment,which experience unpredictable loads,making them susceptible to fatigue failures.
