Fatigue Cracking and Prevention

Fatigue cracking is a phenomenon that occurs in metals due to repeated load, which can lead to failure at loads considerably below the material’s static strength. It is estimated that approximately 80-90% of failures of machineries is caused by fatigue cracking originating in negligence and poor maintenance.

PROSWECO can provide advice in the following areas:

• Adaption of actual design
  • Proper design
  • Modifications of the design
• Failure investigation
  • Determination of root cause
• Repairs of fatigue cracking
  • Recommendations, technology and
    approach
  • Assessment of remaining life length
• Post treatment of welds
  • TIG-dressing
  • Grinding
  • Pickling
  • Shot peeling
  • Assessments of efficiency by post treatment
• Fatigue cracking conditions
  • Assessments for the conditions of various materials
  • Testing and evaluation
