Process Brazing
Commonly used technique for joining steel parts together with nice looking joining areas. Advantages for brazing compared to welding is less heat distorsion and the possibility of joining dissimilar metals. Can furthermore be used for metals with poor weldability.

The parts are joined together using a lower melting metal as filler / binding agent and a flux for activating the surface. Only the filler and not the base material is melted. For steel is often used a combination of 50% Cu, 10% Ni and 40% Zi, that has a melting point about 900 c.

Aluminium parts can be soldered but with difficulty: The soldering agents melting point is only 10-20 degrees lower that the aluminium and there is no red-hot temperature indication like for steel.
