Steel and stainless steel tubes are most commonly joined in the brazing process. Brazing involves the application of heat above 1,000 degrees Celcius. It produces excellent joints, however only with correct preparation. Copper brazing requires highly skilled craftsmen who understand which materials to use and the correct measures, as far as heat, time and filler material.
When metals have surface stress, they can be difficult to work with. Stress can have a range of causes: drawing during stamping, cold working, bending, hydroforming, or other stress-inducing processes.
Annealing removes stresses from materials and results in surfaces that are much more ductile. When residual stress in the base material is reduced through annealing, it makes the material a lot easier to work with.
