Activating submerged arc welding flux
Activating SAW flux contains chemical additives that increase penetration in SAW processes and increase welding speed. This improves production efficiency and weld quality.
Physical-Chemical Mechanism of Action
Activating SAW flux contains special chemical additives that activate metal penetration during welding. These additives react with the metal and trigger rapid oxidation, which accelerates melting.
Metallurgical Relevance & Risks in Welding
The increased welding speed results in more even heating of the weld and reduces the risk of hot cracking. However, overdosing the flux can lead to uncontrolled oxidation and porosity, which can affect the strength of the weld.
Workshop Practice & Instructions
Use the activating SAW flux in the specified amounts. The penetration time should be between 1.5 and 2 seconds. Carefully monitor the heating of the weld and adjust the welding speed accordingly.
