Technologies and emissions

Soldering processes are also subdivided according to
the liquidus temperature of the solder and are used in
different areas:

HIGH TEMPERATURE
SOFT SOLDERING HARD SOLDERING SOLDERING

Liquidus temperature < 450 °C/842 °F > 450 °C/842 °F > 900 °C/1,652 °F

Materials • Copper and copper alloys • Steel • Stainless steel
• Sheet steel • Brass • Nickel
• Aluminum • Copper • Cobalt
• Zinc • Silver (alloys) • Ceramics
• Stainless steel • Gold (alloys)

Application examples • Electronics manufacturing • Instrument making • Electronics manufacturing
• Electrical installation • Plumbing installation • Jewelry making
• Sanitary engineering • Goldsmith work • Heating and air conditioning
• Jewelry and handicrafts • Tool making technology
• Heating construction • High frequency technology • Turbine production

ments, solder alloys (solder wire, solder bars, DAMAGING EFFECT
solder paste) and halogen-free fluxes (mainly
containing rosin) are used for soft and hard
soldering. During the soldering process, large
parts of the flux agent and a small portion of
the solder are vaporized.

This produces aldehydes, gases and aerosols, HUMAN MACHINE PRODUCT
among other things, which have been proven
to be harmful to health. They also have a neg-
ative impact on manufacturing equipment and
products.
