To get a tight and waterproof seal used soldering - the bond metal and molten solder. Called solder tin-lead alloys, which can be easily melted. When soldering the molten solder is placed in the gap between the pre-heated soldering iron parts. Solder fills the pores of the base metal and forms a tight seal. Roofing take soft solder melting temperature to 300 ° C.
On the edges of matched components soldered to remove rust, dirt, grind them to avoid burrs and irregularities. After that ludyat (coated with a thin layer of tin) sites soldering, grinding and ludyat soldering tip. Details are placed on a flat wooden surface (bar). After fitting the edges of details in the space between them with a brush or a thin stick administered zinc chloride (hydrochloric acid). In the event that a large seam, at several positions solder. Soldering tip solder placed at the beginning of the seam and as falling into the gap between the solder seam detail at this point is pressed against a wooden block, and a soldering iron is moved to a new location, etc. The number of solder on the tip from time to time supplement.
Spliced parts during soldering slightly tilted towards moving tips. The clamp is removed from the edges of details only after the solder hardens, and brazed seam matt gray. The seam is then washed under running water or wipe with a swab dipped in a soda solution, and dried with a cloth.
Soldering along with riveting used in the manufacture of equipment, collars for pipes, etc.
