Pressure Vessels

Heat resistant steel that includes Chromium (Cr) and Molybdenum (Mo) is used in order to guarantee strength and toughness in the pressure vessels used in the synthesis of various chemicals in a high temperature, high pressure environment and in power generation etc. The same composition is required in welding materials, and we have developed various such materials to meet the characteristics of each steel material and demand.

Off-shore Structures

Various offshore structures are constructed at underwater oilfields to match the environment and the depth of the development. A strength and toughness suited to the ocean environment is necessary, and a high strength and excellent low temperature toughness are required in the structural steel and welding materials used.

LNG Storage Tanks

Liquefied natural gas (LNG) is widely used as a fuel with a low environmental impact. 9% nickel steel, which has good toughness at very low temperatures, is used in the steel tanks that liquefy and store LNG. A ratio of 9% nickel, equivalent to that of steel material, does not satisfy the requirements made of the welding material, for which a material containing almost 70% nickel is used.

Ship Building

The majority of goods traded in intercontinental commerce are transported by sea. The ships used in marine transport are impacted by weather conditions and can be exposed to dynamic stress due to high winds and waves. Whilst size is restricted by passages such as the Suez Canal and the Panama Canal, the loading capacity of ships continues to increase and excellent design and materials are employed to provide a strength and toughness that ensures safe shipping. Various high-efficiency construction methods that use the most welding material in proportion to the quantity of steel are employed to reduce the construction period.

Automobile

The development of lightweight, fuel efficient cars and electric vehicles that do not use fossil fuels and the outfitting of an EV infrastructure are progressing. Whilst the usage ratio of steel material is decreasing, a reduction in weight by increased strength and improvement of fatigue strength is being explored.

Bridges

As the movement of people and goods increases with economic development, bridges that cross rivers and channels become necessary together with the development of railroads and bypasses to facilitate the flow of traffic. In Japan, a steel material has been developed with consideration for weather resistant properties and an atmospheric corrosion resisting steel welding material is used for such infrastructure developments.

Highly efficient welding processes


Building Structure

In earthquake-prone Japan, large-scale buildings are constructed using a steel frame in order to minimize human injuries due to collapse of buildings. The manufacture of components such as pillars and beams is carried out continuously through day and night in factories primarily using welding robot systems, whilst assembly welding is performed locally by welding operators.
