Welding difficulties

Welding of precision alloys is fraught with difficulties due to the tendency to pore formation with a sharp change in the solubility of nitrogen, hydrogen and oxygen after the transition from solid to liquid state. To obtain pore-free welds an important condition is the cleanliness of the surface of the electrode wire, welded edges, welding consumables and base metal (electrode coatings, fluxes, shielding gases) as well as binding of hydrogen and deoxidation during welding nickel. This is solved by the introduction of strong deoxidants in the weld pool (titanium, aluminum, etc.), as well as the use of coatings or fluxes that can convert hydrogen into stable volatile HP compounds or bind nickel oxides. For this reason, the welding technology can provide reliable protection of the welded area from atmospheric air, degassing of the weld pool and good deoxidation. An effective measure to prevent porosity is short arc welding (up to 1.5 mm), which significantly reduces the flow of gases from the atmosphere.
