Which one is welding defect

• Pinholes

• Lack of fusion

• Craters

• All

Lack of fusion will occur due to

• Poor adhesion

• Good adhesion

Pinholes are generated due to

• High welding temperature

• Low welding temperature

Cracking is formed due to

• Using wrong electrode

• High residual stresses

Gas inclusions are formed due to

• High sulphur content in the electrode

• Excessive moisture from the electrode
