Japanese energy storage resistance welding

What makes JFE Steel a good weld?

The weld has good bond and heat treatment zone. For the quality assurance, JFE Steel introduced a multi-probe system described above, enabling 100% flaw detection with ultra-heavy, 1” thick material. The development of petroleum and natural gas is progressing in the direction of deeper wells, and has expanded from land to the sea bottom.

What makes JFE Steel a weldable 12cr stainless steel linepipe?

Weldabil-ity of JFE Steel’s weldable 12Cr stainless steel linepipe is improved by reducing both C and N to 0.01 mass%, enabling welding without preheating.

How JFE Steel contribute to sustainable growth of society?

JFE Steel is contributing to the sustainable growth of society in energy and other fields by technical devel-opment and supply of high performance steel products which establish the standard for the times. 1) Yuga, M. et al. Yosetsu Kozo Symp. 2002 Koen Ronbun-shu.

Can Chita weld ERW pipes?

As of November 2003, Chita is the only mill which can produce this thickness in ERW pipes. Increas-ing the wall thickness makes it possible to supply pipes with a maximum collapse pressure approximately 1.6 times greater than that of the conventional ones (Fig. 14). Photo 2 shows a macro photograph of the cross sec-tion of the ERW weld seam.

What is JFE Steel?

JFE Steel manufactures ultra-heavy sec-tion plates with sound internal quality for the thick-nesses of up to 240 mm (original slab thickness/product thickness reduction ratio: 1.29) using CC slabs with a thickness of 310 mm, and has already produced more than 60 000 t for various applications.
