They discovered that some coatings created a shielding gasoline that protected the weld pool from contaminants during the environment. Contaminants bring about Porosity and Longitudinal Cracking. With all the weld pool shielded the weld was smooth and sound and could be utilized in different positions in lieu of just flat. I am able to only consider how many times Individuals bare rods would get stuck!
