Problems solved by technology

However, this material is mainly dependent on imports, which has greatly restricted the development of the LNG industry. This product is still in a blank state. Through research and development, a special welding rod for LNG has been preliminarily developed to meet the harsh and severe conditions of LNG. The existing technology Among them, no high-toughness electrode that can meet the cryogenic conditions of -193°C has been produced

Description

technical field [0001] The present disclosure generally relates to the field of welding technology, specifically to the field of welding rods, and in particular to a nickel-based alloy welding rod and a manufacturing method thereof. Background technique [0002] In recent years, China has vigorously promoted and implemented the clean energy strategy. As a low-cost natural gas storage and transportation method, the liquefied natural gas industry is increasing rapidly. LNG equipment needs to meet relatively harsh service conditions such as ultra-low temperature and liquefied gas corrosion resistance. Manufacturing The key material of the LNG storage tank body is nickel-based low-temperature 9Ni steel and welding technology has put forward a huge demand. However, this material is mainly dependent on imports, which has greatly restricted the development of the LNG industry. This product is still in a blank state. Through research and development, a special welding rod for LNG ha...
