Soldering
We offer professional soldering services for components made of non-ferrous metals and stainless steel, utilizing hard soldering technology in a tunnel furnace under a hydrogen atmosphere.
The silver solders we use most often are characterized by excellent properties, good shear strength, and resistance to acids and alkalis, enabling the joining of most metals. This technology ensures very high-quality connections and an aesthetically pleasing appearance of the weld.
We also provide hard flame soldering on semi-automatic machines, which offers very high production efficiency. To achieve the ideal effect, we offer galvanic treatment as well.
Additionally, we offer manual soldering using flux-cored solder. This technology complements traditional flux forms such as pastes, with gas mixtures like propane-oxygen, methane-oxygen, or acetylene-oxygen. The flux-cored soldering technology ensures clean soldering areas, reduced process time, and high efficiency. It has a wide operational range of 760°C to 1205°C and is used for joining brass-brass, steel-steel, steel-copper, copper-copper, steel-brass, and copper-brass.
We offer various partnership opportunities in soldering and welding. If these processes are auxiliary to your business operations, we provide professional outsourcing services.
