Application

Soldering of stainless steel is used to connect stainless steel parts such as roofing sheets, water pipes, drainage. Soldering uses fillers with lower melting points than stainless steel — no more than 450 ° C. The bond strength is usually lower than welded joints.

Preparatory operations

The presence of a strong oxide film on the surface of a stainless steel makes it difficult to solder. A thorough cleaning of the steel surface in the joint area is necessary. Oil and grease can be removed with solvents, and brushing with stainless steel brushes or abrasive emery cloth can be used to eliminate other forms of contamination. Allowed a slight roughness of the surface of the abrasive and improves the adhesion of the solder. It is advisable to perform the soldering operation immediately after cleaning. If this is not possible, the parts for protection purposes may be pre-coated with solder.

Heat

All traditional heating methods can be used for soldering stainless steels. However, the thermal conductivity of austenitic stainless steels is relatively low and their expansion coefficient is high, so make sure that the entire bond region is evenly pressed to the soldering temperature without overheating.

Fluxes

To remove the oxide film on the prepared surface, aggressive fluxes are required. As a rule, phosphoric acid based fluxes are suitable, they have the advantage that they are chemically neutral if the residues remain after the soldering process is completed.

The price is optimal.

Choice of solder

The appropriate solder must meet the expected operating conditions. Factors to consider include mechanical stress, potential corrosion, color matching, contact with food or water, etc. For soldering stainless steels, conventional tin-lead solders can be used. It is recommended that the content of tin is more than 50% to ensure good adhesion strength and minimize the risk of galvanic corrosion in the brazed joint during maintenance. Purely tin solders correspond well to the color of stainless steels and do not darken during operation.

Tin-silver solders

A number of tin-silver solders are recommended for stainless steels, since they are more durable than tin-lead solder, combined with high plasticity.

Final operations

Remove all flux residues immediately after brazing, to prevent corrosion from developing during operation. Suitable hot water, possibly with the addition of a mild detergent. Preferably, running water is used, and a non-metallic fiber brush can be used to accelerate the process.
