In order to support the independent manufacturing of China's 80,000-ton die forging press and millions of kilowatts of nuclear power rotors, the Harbin Welding Research Institute of China National Machinery Research Institute has successfully developed under the support of the national science and technology major projects of “high-grade CNC machine tools and basic manufacturing equipment”. China's first set of 600mm large thick wall full digital narrow gap submerged arc welding equipment and 3500mm ultra-thickness steel ingot automatic flame cutting equipment, achieving a double breakthrough in the "welding, cutting" two extreme size manufacturing process equipment.


It is understood that the main technical indicators of the ultra-large thick-wall all-digital narrow-gap submerged arc welding equipment have reached the international advanced level, and it is China's first super-large thick-walled digital narrow-span submerged arc welding equipment. The 3500mm ultra-thick steel ingot automatic flame cutting equipment is a large-scale casting and forging made by China's heavy-duty enterprises, which exceeds the cutting thickness of 2500mm achieved by developed industrial countries in Europe and reaches the world advanced level.

Application for Guage rod


As an important accessory for railroad tracks, rail gauge tie rod helps to improve the rails` lateral stability and also the ability to keep rail distance. There are some railways that with track circuit, then it should use the insulated rail gauge rod which adopts high insulation resistance material to separate the circuit between two rails apart. Rail gauge may deviated if gauge tie rod is serious lacked, it may cause derailment or even overturned when the train passing by.
