Corrosion issues in solder joint design and service
Corrosion is an important consideration in the design of a solder joint. In the case of a conduit, corrosion from both the outside service environment and the medium being transported within the pipe or tube must be addressed. Solder joints are susceptible to atmospheric corrosion, galvanic corrosion, voltage-assisted corrosion, stress corrosion cracking, and corrosion fatigue cracking. Galvanic corrosion is of particular concern, given the fact that solder joints are comprised of different metals or alloys in contact with one another.
