Bad welds can be traced back to poor workmanship, poor design, or a little of both. Weld defects happen for a host of reasons. Air may creep into the weldment to cause porosity. The wrong amount of heat can cause cracking. Bad welding technique can cause undercuts or incomplete penetrations of one kind or another. Various factors contribute to weld problems, but many lead back to the same place. In fact, most causes of weld defects can be traced back to two general areas: first, a combination of poor instruction and workmanship; second, poor weld design and/or material choice.
