Sintered Flux for SAW
Sinter powder for SAW welding consists of homogeneous alloying components and deoxidizers produced by thermal sintering. It enables targeted metallurgical reactions and improves the weld result.
Physicochemical Mechanism of Action
Sintered powder is produced by thermal sintering, where metal particles bond under high pressure and temperature. This results in a homogeneous material containing both alloying elements and deoxidizing agents.
Metallurgical Relevance & Welding Risks
The sintered powder enables targeted metallurgical reactions in the welding process by creating specific additives and compounds. This can improve the strength and toughness of the weld. However, the powder must be properly dosed and handled to avoid porosity and ensure a homogeneous weld zone.
Workshop Practice & Instructions
Use sintered powder in the SAW method for applications requiring targeted metallurgical reactions. Ensure the powder is correctly dosed and the welding parameters (temperature, pressure) are optimally set. Improper handling can lead to porosity and an uneven weld zone.
