This document discusses different types of welding and soldering techniques. It outlines six learning targets related to explaining soldering processes and classifications. Soft soldering is described as using lower melting point alloys and being used when impermeability is important or high temperatures cannot be withstood. Common soft soldering methods include lever soldering, fire soldering, and soak soldering. Hard soldering uses higher temperature alloys and methods like fire soldering, embedded soldering, and electric arc soldering to join metals with melting points over 500°C for applications requiring strength and high temperature resistance.

9. Soft soldering applied if solder extension have to be
impervious better or not have to too solid and may not
suffer high temperature
Soft soldering most carried out to by lever soldering, fire
soldering, soak soldering and prisoner soldering

10. Hard soldering applied if tying have to be sturdy
and hold up high temperature
Soldering done with method fire soldering,
embed soldering , salt wallow soldering, stove
soldering, glimpse soldering and electrics
