How is the shielding gas used in arc welding?


How is the shielding gas used in arc welding?

Because the metals react chemically to oxygen and nitrogen in the air when heated to high temperatures by the arc, a protective shielding gas or slag is used to minimise the contact of the molten metal with the air. Once cooled, the molten metals solidify to form a metallurgical bond.See all results for this questionsp.info Where was the smothered arc welding process invented?This under powder or smothered arc welding process was developed by the National Tube Company for a pipe mill at McKeesport, Pennsylvania.
