Dear expert,

What is the correlation between diffusible hydrogen and welding current.

How does Welding current affects diffusible hydrogen ? Based on any specific code or theory?

Kindly help to explain.

There is no relation between diffusible hydrogen content and Welding current.

Yes, diffusible hydrogen is more, more arc voltage is required to push the current due to bad conduct electricity by Hydrogen. Example 6010 is required more arc voltage when compared with 7018
