Product Description:

This spray welding machine developed by us is the newest generation of valve sealing surface spray welder. The control system adopts programmable controller to complete the program control, and carries on the spray welding process parameter input and the adjustment on the color touch screen.

The system can store 100 spray welding process menus, and store process parameters can be reproduced by directly calling the corresponding parameters menu according to the work piece type during spray welding. The corresponding parameters can also be conveniently adjusted individually according to the weld pool status during spray welding.

The control panel is also equipped with digital display instruments showing non-transfer arc, transfer arc voltage and current, which can monitor the most important welding voltage and current parameters at any time. 

The spray welding parameters can be programmed in multiple stages to facilitate accurate spray welding of large and small work pieces. Touch screen display is intuitive, can display many parameters, easy to adjust the display interface according to the control requirements, programming is convenient and flexible.

According to the requirements, the control system can configure data recorder to realize the traceability of welding parameters. It can also customize the stepping function of welding torch and realize automatic lap of large width weld.

According to different shapes, locations and sizes of valve sealing surfaces, the machine host, positioner and welding torch can be customized.

The machine is mainly used for spray welding of inner circle, outer circle, circular end face and conical sealing surface with weld bead width less than 50 mm. The width of weld bead can reach 120 mm in special design.

The base material can be carbon steel, stainless steel, heat-resistant alloy steel, nickel-based alloy, and the welding material can be cobalt-based, nickel-based, iron-based alloy powder, which can meet the requirements of manufacturing large-scale valve sealing surface of nuclear power valve and ultra-supercritical steam turbine.
