Minister for Mines visited T-PUT on the „Schweissen & Schneiden“ in New-Dehli
During the exhibition opening, the Union Minister of State for Mines in India, Dr. T. Subbarami Reddy has visited T-PUT. The Minister was impressed by the capability of the welding technology which was presented by Mr. Sandeep Ubhaykar, T-PUT Brand Manager in India.
T-PUT is the leading group brand in India and stands for welding solutions for high demanding applications. Since decades the reputed brands Phoenix, Union and Thermanit have been a synonym for superior and consistent quality.
During the Fair Conference, two papers on T-PUT welding products for power plant applications have been presented by Mr. Gross, Head of Application Department and by Dr. Heuser, Head of Quality Department, to the interested audience including end users, owners of power plants and engineering companies.
The papers described our experiences in development, production and workmanship of matching filler metals to the steels T/P 23, T/P 24, P 92 and VM 12-SHC as well as the welding of dissimilar joints of new power plant steels. Based on the metallurgical properties, the peculiarities in welding and postweld heat treatment for each of the mentioned steels have been discussed.
This highly interesting and important fair offers the unique opportunity of a high level technological exchange of opinions with top class specialists from all over India and abroad. It is an ideal forum to share experiences and visions in order to cope with the future challenges in the welding industry.
ThyssenKrupp's new Furnace 8 – an Example of brilliant Welding Engineering
Following only two years of construction, ThyssenKrupp's gigantic furnace no. 8 in Duisburg-Hamborn was put into operation, after it was finished in December 2007: It will produce two million tons of raw iron per year to satisfy the worldwide increased demand for steel.
Altogether, some 10,000 tons of steel were used for the construction of this modern blast furnace. At peak times more than 1,000 trained builders of all trades were working on the project, with 300 of them being welders. As the main supplier of welding fillers, the Böhler Welding Group met all of the high quality demands with their T-PUT product range, technical welding know-how, and intensive on-site support.

Due to the unusually high variety of single building parts of the blast furnace construction, a corresponding variety of welding tasks had to be met. Their only similarity: Everything was welded manually. Different temperatures, different requirements on stretching and on corrosion resistance, aggressiveness of media, and different materials like high-temperature steels, fine grain steels, and stainless steels had to be taken into account.
The heart of the construction, the stove tank with a height of 40.5 m and a diameter 16 m, where operating temperatures may reach up to 2,000° degrees Celsius, was welded using the metal powder welding rod Union MV Mo. Laypeople will find the mind-boggling maze of pipes especially impressive: They are used for all kinds of different media like, e.g. natural gas, oxygen, nitrogen, blast furnace gas, carbon monoxide, steam, cooling water, waste water, etc..
Among other fillers, Phoenix K 50 R and Phoenix Black 3K were used as welding fillers for the pipe construction, while Phoenix CEL 70 was used as filler for process gas pipes with diameters of up to 3,200 mm. The numerous stainless steel parts, where corrosion protection and thermal stability are the major concern, were welded using fillers from Thermanit A to Nickel based materials.
All these various welding tasks in the construction of the blast furnace 8 pursued one single aim: The on-schedule construction of an exemplary modern, safe, economic, and environment-friendly plant.
