Joining of metals requires more than moving an electrode along a joint. Metals at high temperatures tend to react chemically with elements in the air such as oxygen and nitrogen. When metal in the molten pool comes into contact with air; oxides and nitrides destroy the strength and toughness of the weld joint. To ensure the quality of the weld joint, BESTARC provides the right gaseous shield around the arc for a stronger weld joint.
The arc shielding of BESTARC provides thin and easily detachable slag that refines the weld bead and ensures uniform cooling of the weld deposit. Therefore, the arc shielding not only protects the arc, but also improves the quality of the weld.
