Our computerized brazing controls and maintains the hydrogen and nitrogen gasses in the oven. Our oven was produced by Thermic Service Company of Switzerland. Such applied brazing technology creates joints high in strength and aesthetics.
All brazed components are cleansed in a five chamber computer-controlled washing machine to remove impurities and ensure a ready-to-deliver product.
The maximum brazing temperature is 820̊C. If needed, we can increase the brazing temperature by installing additional heating equipment.
Brass bodies are also milled and turned by means of a modern CNC center.

This method is widely used if high quality joints are required, i.e. in aviation industry, medical equipment, industrial automation or special tools manufacture.
Another name for this method is plasma arc welding or PAW. For welding applications plasma arc welding is used in the range of microplasma welding (where welding current is set in the range of 0,1 A to 20 A).

Brazed parts are assembled on spindles on a rotary table. This technology is often called “flame brazing”. Wellda uses propane gas.
Brazing at 650̊C with silver rings as joining material.
Brazed parts are galvanized to clean and finish them. Wellda has partnered with a leading galvanic company.
Quality is assured through batch testing and visual inspection of each component before shipment.
