Tube to Tube Sheet High Frequency Welding Machine Automatic
Automatic welding procedures with high automation and welding
Collector ring, integrating welding wire, compressed air and
welding gas access, to realize infinite rotation without winding.
Through orientation tooling to realize automatic positioning
function in torch, to compensate negative effect for tube tilting
with below 3° angle.
Colored HMI touch screen with audio-visual and user-friendly
interface. Welding parameters can be set by segments. 20 sets of
welding specifications can be stored. Setting, invoking, modifying
and saving on welding parameters via touch screen.
Pneumatic clamping, no need for manual support during working. One
operator can operate several machines in the same time.
Compacted, convenience for operation and maintenance.
Equipped with a import pulse power source to realize the deep
penetration weld seam with small spatter；Higher welding efficiency,
with the 51mm diameter pipe`s welding time just 30 seconds;
Disposable welding qualified rate of 99%.
Reserved intelligent digital interface to linking intelligent
workshop management system(iMES).
Specialized for tube to tube sheet welding with orthogonal joints
of convection tube bundle, smoke tube and air preheater tube box in
boiler and pressure vessels industry, adopt MAG welding process,
applicable to various materials such as carbon steel, stainless
steel and so on.
