Weldability of ABS EH36 steel plate

At present, the localization of high-tech ships and marine engineering in China is based on the importation of high-end materials and technologies. In order to promote the development of China's shipbuilding industry and offshore oil industry and ensure the safety of China's energy, transportation and other industries, a large number of key technologies need to be broken through. One of the core issues is the research, development and application of high quality ABS EH36 steel plate etc. shipbuilding and offshore engineering steel.

Weldability is one of the key issues of ABS EH36 steel plate etc. hull structural steel. In recent years, in order to reduce the cost of construction and improve the productivity of shipbuilding, shipyards strongly require the use of large-wire energy welding. 100kJ/cm to 500kJ/cm welding is widely used abroad. To this end, a series of large-wire energy welding hull steels have been developed, such as YP335 steel developed in Japan in the early 1980s, YP390 steel developed in the mid-1990s and YP460 steel currently being developed. At present, in the field of offshore engineering, such as platform use ABS EH36 steel plate, also requires to adopt high-energy welding to improve construction efficiency.
