Concentrated Calcium Chloride Aqueous Solution

Calcium fluoride, fluoride, reading, magic, fluoride and strontium fluoride contribute to the dissolution of oxide oxide, which is always present on the surface of aluminum and its metals, and to transfer it into the slag, and also sufficiently reliable protection of the molten metal of the weld pool and metal of the zone of the zone of the zone of the area of the zone affected by the zone of the zone of the area of the zone of the zone of the zone of the zone of the zone of the zone of the zone of the area of the zone of the zone of the zone of the zone of the zone of the zone of the zone .

For the manufacture of flux in the form of Iasta, the composition of the flux contains co-centrifuged aqueous solutions of calcium chloride and calcium chloride, plays the role of binding components, and reduces the adhesion of the components f: 1nus flux with welded plates.

The need to introduce simultaneously two binding components, the late ternary aqueous solutions of potassium chloride and calcium chloride, is caused by the following.

With the introduction of only a cop- centred aqueous solution of chlorine calpe as a binder com- partment, the required adhesion between the components, as well as the flux and welded joints, is not reached in the composition of the flux. Introducing the flux as a binder for only a concentrated aqueous solution of calcium chloride provides high connectivity of the flux components and the adhesion of the flux to the welded nlastypes, however, after welding, the slag is removed with great difficulty due to the strong adhesion. With the introduction of the flux in both of these bonded components in a ratio of approximately 1: 1, a sufficiently rapid staining of flux and flux components with welded plates is achieved, as well as satisfactory separation after welding slag crust and flux residues from welded parts.

The snake hardened metal structure and the hip cathode is blessed with high resistance to the formation of hot tertiary compounds, and contributes to the improvement of plasticity of welded joints.

In the welding process, the development of (1) luce (ensures reliable penetration of the rascene-lane metal from the atmosphere, preventing hydrogen from penetrating into the liquid metal of the weld pool in the environment. The content of oxygen in the weld metal is achieved, among other things.

When using the proposed fusion flux welding in the form of a paste, it is applied to the surface of the welded parts near the edges and is dried at a temperature of 70-100 ° C for 5-10 minutes.
