Assessment of the size, shape, and depth of welding arc burns with comparison to welding position and currents. Methods were developed to categorize the arc burns and metal hardness measurements were taken at various depths of the welding arc.
This study attempts to establish correlations between the internal dimensions of an arc burn, such as depth, and surface dimensions, such as length and width. The results show that only 10% of all possible arc strikes would be deeper than predicted…
