what type of welding defects are seen? measures for reducing welding defects

Question

Accepted Answer

Welding defects include porosity, cracks, incomplete fusion, and distortion. Measures to reduce defects include proper training, inspection, and maintenance.

Porosity: caused by gas entrapment, can be reduced by proper shielding gas and electrode selection
Cracks: caused by high stress or improper cooling, can be reduced by preheating and controlling cooling rate
Incomplete fusion: caused by insufficient heat or improper technique, can be reduced by proper technique and inspection
Distortion: caused by uneven heating or cooling, can be reduced by proper clamping and fixture design
Measures to reduce defects: proper training and certification of welders, regular inspection and maintenance of equipment, use of proper welding procedures and techniques
