Fatigue performance of a cold

What is the fatigue performance of resistance spot welds

Indeed,a hole,up to 1/3 of the diameter of the weld,may be drilled through the centre of the weld without substantial effect on the fatigue performance.One technique which has been used in a few special cases to improve fatigue life significantly,is to cold compress the weld area after welding.Study on Simplified Test Method about Fatigue Performance The objective of this investigation was to develop a test methodology to assess the fatigue performance of cold patch asphalt mixtures,potentially usable in the field as a quality control method.The methodology was developed by identifying the relationships between the parameters from a Laboratory Fatigue Test (IDT,according to ASTM D4123 ),and the penetration rate (NPR) from a lighter Study on Simplified Test Method about Fatigue Performance The objective of this investigation was to develop a test methodology to assess the fatigue performance of cold patch asphalt mixtures,potentially usable in the field as a quality control method.The methodology was developed by identifying the relationships between the parameters from a Laboratory Fatigue Test (IDT,according to ASTM D4123 ),and the penetration rate (NPR) from a lighter
