This system is specially designed for welding on the inner walls of valves and pipe fittings. It is suitable for workpieces made of carbon steel, stainless steel and other metal and alloy materials, and can be used for welding on their sealing surfaces and outer surfaces. Suitable for workpieces with a diameter of 40-2000m and a weight not exceeding 15000kg. The system is equipped with a servo cross slider, HMI touch screen controller, workpiece servo turntable and cross manipulator. It is easy to operate, has high control accuracy and process repeatability.<br> Key Features:<br> 1.Heavy-duty column and boom structure for robust performance<br> 2.Motorized slides enabling high-precision positioning<br> 3.Versatile selection of turntables and positioners to match specific needs<br> 4.Compatible with components up to 2000mm in diameter<br> 5.Impressive weight capacity of up to 15,000kg

The equipment is used for cladding the inner wall of the pipeline. The workpiece is horizontally mounted on the welding chuck and driven to rotate by the turntable. Two uniquely designed inner wall cladding guns are spaced at a certain horizontal distance and supported by two parallel steel wire ropes tightened on the welding machine. The horizontal drive mechanism drives the welding gun to move inside the pipeline to complete the welding trajectory. Automatic hot wire TIG cladding is achieved through the linkage control of the welding power supply, hot wire power supply and welding machine. The equipment consists of welding power supply, hot wire welding power supply, wire feeding system, external high-frequency module, welding machine body, double inner wall cladding guns, electrical control system and water cooling system, welding arc observation system, and safety assistance.<br> Key Features:<br> 1.Dual-gun collaborative welding boosts efficiency for large-scale pipe cladding<br> 2.Welds 6-26 inch pipes (≤12m length), min post-clad ID 150mm<br> 3.AVC technology maintains stable arc length, ensuring weld consistency<br> 4.Intelligent control with 15-inch touchscreen, Chinese-English interface<br> 5.Hydraulic wire rope suspension minimizes gun vibration during welding

This equipment is specifically designed for surfacing welding the inner hole surface and shallow grooves of steam turbine valves. With a stationary workpiece design, its ETR infinitely rotating welding head (eliminating cable winding concerns) drives the welding torch for circular welding, enabling in-site repair of valve internal surfaces without disassembly, thereby significantly improving maintenance efficiency and cost-effectiveness.<br> Key Features:<br> 1.On-site repair without valve disassembly, reducing downtime drastically<br> 2.360° infinite rotation eliminates cable tangling, ensuring weld consistency<br> 3.Supports stainless steel, nickel alloys for corrosion/heat resistance
