Kobe Steel's Netherlands Unit Begins Production of Flux-cored Welding Wire for Carbon Steel
- This type of welding wire is commonly used to weld ordinary steel, which is used in large quantities in shipbuilding and offshore marine structures, such as oil rigs.
- Kobelco Welding of Europe started out by manufacturing flux-cored welding wire (FCW) for stainless steel in 1995. Production capacity is approximately 1,000 metric tons per year.
- However, with demand for carbon steel FCW growing in Europe, Kobelco added production capacity of 6,000 metric tons per year for this type of welding wire, investing 10.9 million euros (about 1.5 billion yen).
- This will enable Kobelco to produce a combined total of 7,000 metric tons of welding wires in 2008 when full production is anticipated to be achieved.
- Kobe Welding of Korea in South Korea is also increasing production capacity.
- In China, Kobe Welding of Tangshan Co., Ltd. will commence production of carbon steel FCW by the end of this year.
- Through these undertakings, the Kobe Steel Group's total production capacity of carbon steel FCW - in Japan and overseas - is anticipated to increase to approximately 120,000 metric tons per year.
- Flux-cored welding wire consists of a steel sheath with flux in the middle.
- FCW is generally around 1.2 mm to 1.6 mm in diameter.
- Flux contains a deoxidant, slag generator, arc stabilizer, alloys, steel powder and other substances.
- Flux composition contributes greatly to the mechanical properties, welding workability and other capabilities of the welding wire.
