The liquid used in welding penetration test is dye penetrant.

• Dye penetrant is a liquid that is applied to the surface of the weld.

• It seeps into any cracks or defects in the weld.

• After the excess penetrant is wiped away, a developer is applied to make the defects visible.

• This test is used to check the quality of the weld and ensure it is free from defects.

The voltage and current used in welding depend on the type of welding process and the materials being welded.

• For example, in shielded metal arc welding (SMAW), the voltage typically ranges from 20-30 volts and the current ranges from 50-200 amps.
