Development prospect of welding electrode

In today's era of rapid development of science and technology, welding has successfully completed its own transformation, and China has become the largest producer of welding materials in the world. Welding has developed from the traditional hot working technology into an engineering and technical discipline integrating materials, metallurgy, structure, machinery and electronics. Modern buildings, bridges, shipbuilding and other industries consume 300 kilograms of welding materials per kloc-0/ton of steel, while in general engineering construction, 30% of steel needs to be welded. With the increase of welding steel consumption, the consumption of covered electrode will also increase simultaneously. According to the statistics of the national industrial department, the annual demand for welding electrodes in China reaches150,000 tons, but the actual output is less than100,000 tons. The market gap is widening, the price remains high and the product supply is tight. According to this development trend, we predict that the demand for covered electrode will increase by 100 times or more in the future.

At present, there are not many manufacturers in covered electrode, most of which are state-owned enterprises, and the output is far from meeting the market demand. Covered electrode still holds an absolute monopoly position in sales. The coated electrode has a huge market space, but the traditional coated electrode has too many shortcomings and too much equipment investment, which makes ordinary investors daunting. ...

Under this huge business opportunity and good development prospect, Huaneng Shengjie researchers, together with relevant experts and professors, have successfully developed new high-efficiency and low-carbon covered electrode production technology and equipment through repeated technological innovation of traditional covered electrode equipment. The products produced by this technology and equipment are not only scientific and reasonable in formula, but also can be used to produce various types of covered electrode. Its product quality advantages are incomparable to traditional covered electrode: stable arc, small splash, uniform slag coverage, easy slag discharge, good weld formation, good metal strength, plasticity, toughness and porosity resistance, which truly embodies high quality and low price, and turns waste into treasure.
