• Inconsistent and unclearly defined fusion line
• Weld bead radius is smaller than tube wall
  thickness
• Weld bead does not adequately contact and fuse
  the both tubes

Examples of Passing Welds

• Moderate Heat Discoloration
• Weld bead radius is approximately the same as
  tube wall thickness
• Clearly defined and substantially uniform width
  fusion line, no burn - through

• Failure was not at the weld
• Weld bead radius is approximately the same as
  tube wall thickness
• Moderate Heat Discoloration
