Ensuring Overmatching Strength in Pipeline Girth Welds
A fundamental rule of welding engineering is that, in general, the strength of a weld should be greater than the strength of the base materials being joined. This is sometimes taken to mean that the strength of the weld should be greater than the specified minimum strength of the base materials being joined.
