Features of soldering steel
Soldering of steels should be done with the use of solder, the composition of which is different from the chemistry of the raw materials — steels. In most cases, soldering of steels is used in tool production, as well as in the repair of steel pipes, unloaded car parts, etc.
For soldering steel are needed:
- Lead-tin solders of the type POS-40, POS-61, etc .;
- Flux, whose task is to remove the oxide film, which will be formed on adjacent parts, heated to temperatures not lower than 240… 300 0 C. For steels, acidic fluxes are required;
- Soldering iron or gas heater. The power of the soldering iron depends on the size and length of the soldered joint, but can not be less than 80 W.
It should be noted that the melting temperature of the selected solder should not be lower than the maximum heating temperature of the steel product during its subsequent operation (the temperature margin must be at least 30… 50 0 С).
Electrovek-steel company offers at a reasonable price of the manufacturer a wide range of tin and tin solders, which are used for soldering steels. The supplier guarantees prompt delivery of products to the point marked by the customer.
Conditions for high-quality soldering are tin
It is inadmissible to use for soldering surfaces that have traces of oil and grease, as well as oxide films. Removal of these contaminants must be carried out in a combined way — chemically, with the help of solvents, and mechanically, using hard metal brushes.
For qualitative soldering, uniform heating of the surface of the future weld is important. At the same temperature, which is created by an additional source of heating should be lower than that which develops on the tip of the soldering iron: thus, the temperature background will be more homogeneous. Otherwise, the solder may not harden. The heating temperature is selected experimentally, depending on the chemical composition of the steel, but with an increase in the percentage of carbon it will be less.
In the absence of zinc chloride before soldering, the steel parts are subjected to tinning — preliminary coating of the surface, cleaned of fats and oils with a thin layer of tin solder: the quality of the soldering will improve.
