Plasma Arc Additive Manufacturing Technology
Plasma arc wire feeding additive manufacturing (PAW,Plasma Arc Weld) uses plasma arc as a heat source to scan the forming path obtained by layering parts, forming a moving molten pool on the metal substrate, melting metal droplets formed by externally filled metal wires, continuously feeding them into the molten pool, and realizing the forming of parts by accumulating metal materials layer by layer on the forming path.
Advantages of plasma arc additive manufacturing
The plasma arc wire feed additive manufacturing system uses the plasma power supply as the heat source, and the energy density can reach more than 106W/cm3, which is equivalent to the laser. At present, the wire feed fixture of the plasma arc additive equipment on the market is fixed on the welding torch, and the wire feed direction cannot be changed by following the change of the moving direction of the welding torch. The TSC-PWAAM realizes the front-side wire feeding, solves the molding defects caused by the different wire feeding direction and molding direction, and ensures the same printing in all directions. The welding current and wire feed speed can be controlled separately in the forming process, and the process parameters can be selected more when forming different materials, and the forming raw material is metal wire material, which has higher material utilization rate and higher forming efficiency than laser powder additive.
TSC-PWAAM size supports customization, and can realize additive manufacturing of various large-size metal components and repair and remanufacturing of various metal components. It has many advantages such as low equipment cost, easy modification, high deposition rate, saving raw materials, no size limitation and easy real-time repair.
The equipment is multi-purpose, which can be used for direct forming of additive manufacturing and wear repair of parts. It is very suitable for aerospace and civil fields.
Plasma additive manufacturing forming materials may include aluminum alloys, magnesium alloys, various types of steel alloys, high temperature alloys, titanium alloys, and the like.
