Sintered flux manufacturers share that sintered flux is an excellent, environmentally friendly and energy-saving flux. It refers to the prepared wet flux, which is calcined at a high temperature of 750~1000℃ to produce the required fine solder particles, which is called sintered flux. So what are the characteristics of sintered flux? Let's take a look with the sintered flux manufacturer below. General characteristics: The melting point of the flux is relatively low, the bulk density is relatively large (usually 1.0-1.8g/cm3), the particle size is uneven, but the strength is relatively high. It consumes a lot of electricity when in use, and the cost is high, and the amount of flux does not change much during welding.

Sintered Flux Manufacturer

Sintered flux manufacturers share the characteristics of sintered flux: high-speed welding performance: uniform welding bead, not easy to produce porosity and slag inclusion. Large welding performance parameters: obvious piping stamping, easy to stick to slag. Hygroscopicity: small, do not dry before use. Rust prevention: more sensitive. Toughness: Mainly affected by wire composition and magnetic flux alkalinity. Change composition: Welding process parameters change uniformly and have small fluctuations. Welding performance: The change in the analysis of the weld metal composition has little effect on the weld, the development of deoxidation ability is poor, and it is not easy to add alloys. The sintered flux produced by our company has a favorable price. If you are interested in buying, please contact the manufacturer.

How to choose the type of sintered flux in operation? In the case of higher than sj101, sintered flux has good welding processability and slag removal, and can be flexibly transferred to the weld to meet the requirements of different properties and compositions. Used in occasions with high requirements for slag removal and mechanical properties. But sintered flux is easy to absorb and wear, so it must be baked before welding and used with baking. Generally speaking, the higher the alkalinity, the fewer impurities in the weld, the more favorable the alloy (sintering agent) is transformed, and the higher mechanical performance requirements can be met. However, the quality of the groove surface is strictly required, and DC power supply and reverse connection operation are adopted.

There are inevitably welding impurities and harmful elements in low-alkali sintered flux, which limits the further improvement of its welding performance. However, the requirements for the power supply are not high, and the requirements for the surface quality of the groove can be appropriately relaxed. Sintered flux manufacturers suggest that the sintered flux should be selected according to the steel, plate thickness, joint form, welding equipment, welding process and performance requirements, etc. to select the appropriate combination of solder.
