What are the different types of defects in welding?

We can break down weld defects into the following main categories:

• Inclusions.
• Lack of fusion.
• Porosity.
• Undercut.
• Under-fill.
• Cracks.
• Excess reinforcement and excess penetration.
• Over-roll/Overlap.

What are the 7 common welding defects?

How to Identify the 7 Most Dangerous Welding Defects

• Types of Welding Defects.
• Slag Inclusions.
• Porosity.
• Undercut.
• Weld Crack.
• Incomplete Fusion.
• Incomplete Penetration.
• Spatter.

What are the defects in gas welding?

Internal Welding Defects are defects that occur at some depth in the material. They are visually invisible since they are not present on the surface, but they carry equal weight as the external ones. These defects include incomplete fusion, slag inclusion, and incomplete penetration.

How do you prevent welding defects?

You’ll need to remove the impurities in your metal and preheat it as required. Additionally, use the proper joint design for the material and properly cool the welded area. Be sure to weld enough sectional areas, too. Use the right amperage current and welding speed.

What are 4 preventive measures of excessive weld reinforcement?

Preventive Measures: Use appropriate welding amperages, manipulation speeds, arc lengths (arc voltages), and electrode travel and work angles.

What is the 10 welding defects?

Among the discontinuities related to the welding process, one can mention 10 types: Lack Of Penetration or Incomplete Penetration. Lack Of Fusion or Incomplete Fusion. Undercut.

What are the 6 welding defects?

What are common weld defects?

• Lack Of Penetration or Incomplete Penetration.
• Lack Of Fusion or Incomplete Fusion.
• Undercut.
• Spatter.
• Slag Inclusions.
• Cracks.
• Porosity.
• Overlap.

What are the 12 common discontinuities?

What Are Some Common Welding Discontinuities?

• Porosity. Porosity occurs when gas becomes trapped in the weld pool, forming permanent bubbles as the metal cools from a liquid state back to a solid.
• Inclusions.
• Inadequate Joint Penetration.
• Incomplete Fusion.
• Arc Strikes.
• Overlap.
