Large orbital automatic welding machine
Application:
Parameter:
Pipe outer diameter: φ3mm ～φ180mm;
Protecting air: argon.
Advantage
1. Double clamping positioning, good positioning effect, no need to locate spot welding, improve welding efficiency.
2. Pulse power supply, closed design of the welding head, good protection effect, uniform and beautiful weld seam.
3. Lightweight structure design, suitable for assembly site with small space.
Description:
KHGC Closed Head Orbital Welder is a specialized auto arc welding machine whereby the arc is rotated mechanically through 360° around a static work piece of tube to tube with tube specification φ3～φ114 mm and tube thickness 0.8～3mm.
KHGC could address the issue of operator error in gas tungsten arc welding(GTAW).
KHGC is composed of power supply, control system,cooling system and welding head.
KHGC could process carbon steel, alloy steel, stainless steel and titanium alloy.
