copper to stainless brazing

When you need to join two pieces of metal together, copper to stainless brazing is a great alternative. This method has a wide range of applications, including appliances and autos. Its benefits include being non-toxic, ecologically safe, and simple to use. To begin, make sure you have the necessary equipment and supplies, including filler metals.

Electron beam welding

For stainless-steel brazing copper junctions, EBW has become the favored welding procedure. This is due to its high energy density and quick penetration of the copper's surface. Furthermore, the churning movement promotes copper mixing and dispersion in the weldment zone.

The capacity of EBW to resist hydrogen embrittlement is, however, its most significant and practical consequence. This is due to the fact that hydrogen is a gas that develops in copper during remelting. It is found on the grain borders as cuprous oxides. It is a prelude to the establishment of porosity.

Copper's molten form has an oxygen concentration of around 150 parts per million (ppm). The maximum allowed content is 400 ppm. The presence of oxygen reduces welding performance and promotes porosity development.

An adequate beam oscillation pattern causes churning in the liquid, resulting in an ideal degassing environment. An incorrect beam oscillation pattern, on the other hand, leads in an excessive degree of porosity creation.
