- Flux used as an auxiliary agent for welding high-alloy steel (nickel content below 25%).
- For welding medium- and low-alloy steels when it is necessary to obtain a joint with high strength and operational parameters, especially when access from the root side is difficult or impossible.
- Eliminates the need for using root forming backings, as well as the gas protection typically applied from the root side to prevent oxidation of the molten metal.
Instructions for using SOLARFLUX fluxes:
1. Removal of greases.
SOLARFLUX removes all contaminants and oxides except greases and oils. These must be removed using the appropriate solvent or by degreasing with steam.
2. Mixing flux with alcohol.
Measure out enough flux to cover production for a single day. The remaining flux should be sealed tightly in a container. The measured portion of flux should be mixed with alcohol to form a paste with the consistency of thick cream (about 170-200 g of alcohol per 1 package of flux).
3. Mixture reaction
After mixing the flux with spirit, wait a few minutes for the chemical reaction between the components of the paste to occur. During work, add alcohol as needed to maintain the required consistency. Do not use pastes that have dried up completely.
4. Application of SOLARFLUX to bonded elements before assembly.
A thin layer of SOLARFLUX applied to the joining edges prevents the formation of oxides. Assembly and welding must begin immediately after application of the flux. For additional oxidation protection, a thin layer of flux can be applied several days in advance and thickened just before welding. In every case, SOLARFLUX flux should be applied to the lower part of the joint (root side). The welded elements must be supported in such a way that the flux does not contact the base surface.
5. Residue after SOLARFLUX welding is chemically inert and has a high melting point. The thin glassy layer formed during welding adheres tightly to the welded material and does not need to be removed. Exceptions are: when there is a possibility of residue contacting food or beverages, when welded elements will operate above 550°C in an oxygen atmosphere, when future use requires a clean weld surface, or if the client requires clean welded joints. If removal of flux residue is necessary, do so by grinding, sandblasting, or abrasive paper treatment. When welded elements are thin, an etching bath (6-7 min) in ANTOX 80E or application of ANTOX 71E Plus or MOST Blue pickling and passivating paste on the weld is recommended.
