"Welding wire" the national standard seminar on June 14 to 16 held in Qingdao Garden Hotel, Metallurgical Industry Information Standards Institute Standards Commission steel wire rod and steel sub-committee secretary Wang Lingjun chaired the meeting, Vice Qinggang general manager, chief engineer Wang Qingxian and national welding materials Quality Supervision and Inspection Center, deputy director Chu Following the king speech, respectively, from across the metallurgical experts attended the meeting.


According to the National Standards Commission Dec. 2, 2010 issued a comprehensive [2010] No. 87 "issued in 2010 revised national standards program notice" requirement, from Qingdao Iron and Steel Co., Ltd., Metallurgical Industry Information Standards Institute and other units responsible Amendment "welding wire" the national standard (project Project No. 20101759-T-605), in the extensive solicitation of opinions, based on the group through the preparation efforts, has raised the standard discussion paper. Wire rod and wire by the Technical Committee entrusted Qingdao Iron and Steel Co., Ltd. hosted the seminar.


Qingdao Steel vice president, chief engineer Wang Qingxian said welding steel products is the traditional advantage of Qingdao Steel products in the industry has been in a leading position in the domestic market share of sales accounted for more than 60%; its main purpose is the production of gas-shielded welding wire wire rod, submerged arc welding wire rod and wire rod ordinary welding rod. Qingdao Steel production specifications for the 5.5mm ER50-6 E steel welding wire components, steel, microstructure, mechanical properties more uniform and stable; rod pull at higher speeds, without intermediate annealing can be directly pulled pull to φ1.0mm finished; weld spatter, weld smooth appearance, high strength, reached the advanced level, in addition to conventional ER50-6 wire with wire rod, in recent years also developed a higher value-added ER70S-G with titanium steel wire, which can meet high current, high efficiency, automated welding requirements and 60kg class, 70kg grade high strength steel wire, covering structural steel wire, chrome molybdenum steel wire, weathering steel wire and other series. In 2009, Qingdao Steel welding wire through the China Classification Society temporary factory authorized. To further meet the market demand for high-end wire and maintain outstanding competitive advantages, Qingdao Steel Technology Center established a special welding steel sales and research team, flexibility and ability to conduct new research.


Wang Qingxian say, Qingdao Steel has always actively implement standardization strategy to deal with technical barriers to trade, and vigorously promote independent innovation, constantly upgrading the product structure. So far, Qingdao Steel has been involved in GB / T 4354 high carbon steel wire rods, GB / T 8731 cutting steel, GB / T 14981 Hot rolled wire rod size, shape, weight and tolerances, GB / T 24238 pre- hot rolled steel wire and strand stress rod, GB / T 24242 silk non-alloy steel wire rod and other 10 national standards and revision. March 2011 assumed the chair Amendment GB/T3429 "welding wire" work. For the good of the standard revision, Qingdao Steel Group Corporation established a standard project chief engineer, head of the working group. After starting the work plan, the first of the relevant domestic and international standards and literature retrieval, translation, research, and conduct extensive market research activities. Since then, with the Institute of welding materials and related units experts share their knowledge, and on the Internet solicit opinions from all sides, thereby defining the principles and main technical standard revision course, after repeated changes are proposed standards discussion paper.


Wang Qingxian that if as a standard product, then this product is to go through the draft, comments, discussion, modification, validation, and other machining processes to complete. To improve the quality standards required from the start to improve the quality of each process. Experts hope that this discussion will be taken under the wing, put forward your valuable opinions, so that the revised standards have advanced, effectiveness and adaptability of the market.


At the meeting, the experts discussed carefully standards, proposing some modifications, meeting a success.
