Hot wire TIG automatic welding machine

　　In the oil and gas exploitation,oil and gas storage and transportation,sewage treatment and other industries,they often encounter the harsh operating conditions of corrosive media,such as H2S,CO2,Cl-,etc.,and need to build up a layer of stainless steel or nickel-based alloy on the inner wall of pipeline components such as valves,insulation joints,filters,etc.to achieve the corrosion resistance of alloy pure materials,while the cost is greatly reduced.The automatic hot wire TIG surfacing technology can be used for high quality anticorrosion alloy surfacing.

　　Hot wire TIG welding is a new process based on traditional TIG welding.TIG welding of hot wire can improve deposition efficiency and welding speed through the coordinated control of welding current,hot wire current and wire feeding speed,and reduce the dilution rate of weld to 5%~10%to guarantee the content of alloy elements.

　　The welding process with high automation and high welding quality is the most advanced surfacing welding method at home and abroad at present.

　　Equipment capability:

　　Maximum outside diameter of workpiece--1500mm

　　Minimum inner diameter of workpiece-46mm

　　Maximum depth of workpiece--800mm

　　Maximum weight of workpiece--3 tons
