Proper weld identification: Overlap and undercutting are two main causes of weld failure. Proper washing
of the weld bead into the sides or “toes” of the weld is important. Keep the welding electrode or the TIG
tungsten and welding arc within the weld joint to prevent overlap. Pausing on the sides of the welds to
wait for the sides to fill reduces the chance of undercutting, even if the current is a little too high. If it is
possible, with any practice weld, cut the joint down the middle, lengthwise, or place the weld in a vice and
use a hammer to bend the metal over the weld area until it is either broken or bent 90 degrees. This
destructive testing method will help you improve your skill by revealing faults and flaws in your welds.
