When open holes have been completely melted through the base metal, generally caused by too much heat or poor welding motions, it is identified as:

Weld fatigue is related to dynamic weld loads over a period of time.

Correctly identify the part indicated by the arrow in the figure below.

Welds can fail due to:

The power output of a single inverter GTAW welder would be:

An increase in dust and dirt within the welding transformer will effectively its duty cycle.

Discontinuities are interruptions of the typical structure of a weldment, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of the material or weldment that makes the weld rejectable.

According to the American Society of Mechanical Engineers (ASME), the highest percentage of welding defect causes are:

Burn-through can result from poor joint fit-up.
