Properties of tin and features of its production
The gray and white sheet metal is sheet rolled from soft mild steel type Steel 05, which is covered from above with pure tin. Such a coating, which is applied by the hot dip method, or by galvanization, adheres well to the base metal and improves the soldering process, because non-corrosive fluxes are used. The usual thickness of the coating for sheet metal is in the range 0.0015… 0.02 mm. Galvanic tin plate is also produced in the form of large rolls, which later are blown into the ribbons of the required width.
The quality of the electroplating is usually checked visually, by gloss: the surface can be matte or with dim reflection. In the latter case, the surface is clarified by melting. After clarification, the tin plate acquires improved anticorrosion characteristics, and is also better suited for soldering. Tin coatings on the clarified white sheet have a thickness of 0.0003… 0.0015 mm.

Technology of soldering tinplate
Regardless of the thickness of the surface coating of a tinplate, it is necessary to solder using anti-corrosive fluxes. The soldering process is facilitated with increasing coating thickness. Therefore, a broader application (with the exception of cans) was obtained with tinplate, which is made using hot dip technology.
Due to the increased fusibility of the solder, there is no need for a strong heating of the soldering zone, which is carried out by the flame of gas burners: excess temperature worsens the quality of the finished joint.
For soldering of tinplate, solders containing tin and lead are used, and the amount of tin is from 40 to 60%. Such solders are distinguished by their ease of use, low melting point, and good capillary properties.
Tin special surface preparation for soldering does not require, with the exception of removal of fatty and oily surface contaminants. For soldering are used:
- Electric soldering irons;
- Induction heating plants;
As fluxes, rosin-based compounds are used that provide sufficient protection for both metal and solder. To increase the productivity of tin-plate soldering, activated rosin fluxes are used.
Soldering is carried out «in an overlap» or «in the lock», with gaps not exceeding 0.025… 0.030 mm.
