The SE-TW 400 combines typical features of the arc spray technology such as reliability and robustness with the highest demands for process control and system compatibility of modern arc spray technology. The SETW 400 is designed to process all conductive wires relevant to thermal spray, solid wires and cored wires. New technology for the power supply is a combination with the highly accurate wire feed and the controlled air cap geometry allows controlled and uniform energy transfer on to the wire material. This allows the energy transfer to be adapted to the needs of the applications. SE-TW 400 is a New Generation High Velocity Arc Spray (HVAS) Technique which has great opportunities where near porosity free high quality coatings at the most economical cost in the engineering design required. In comparison with other arc spray equipment, the SE-TW 400 concept enables the user to process wires at decreased voltage levels.
Simple and low cost operation, with infrequent consumption of spare parts and high reliability in continuous application, are key design components of the SE-TW 400.
OPERATING PRINCIPLE & SPECIFICATION:
The SE-99 Metallizing Gun utilizes electrical energy to melt metal and compressed air to atomize with high velocity and project the molten metal in a super fine spray on to a prepared work surface. During operation, an electric arc is maintained between two metal consumable wires.
The wires are continuously fed to the arc position by a drive mechanism operated by an Air motor. Metal wires are melted by the head compressed air directed across the arc. Wires are fed at a small-included angle between them, (about 30°) to get a narrow spray pattern.
A narrow angle also increases the cross sectional area of the wire tips exposed to the arc. This allows wires to absorb more heat and maintain a more stable arc.
