Active Flux
Metallurgically active welding flux contains special additions that improve deoxidation and the chemical composition of the weld metal. It helps minimize alloying losses during the melting process.
Physicochemical Mechanism of Action
Metallurgically active welding powder contains additives like silicon or titanium that become active in the molten pool. They bind oxygen and prevent porosity. At the same time, they correct the chemical composition of the weld metal by compensating for alloy losses.
Metallurgical Relevance & Risks in Welding
Using active powder improves weld quality through better deoxidation and more precise composition. Without active powder, alloy losses can lead to uneven toughness or porosity, affecting the strength and reliability of the weld.
Workshop Practice & Instructions
Use metallurgically active welding powder for welding jobs with high demands on toughness and deoxidation. Ensure the powder is mixed correctly and used in the right ratio to the base metal. For special alloys like austenitic or martensitic steels, choosing the right active powder is especially important.
