Flux cored wire manufacturing feasibility investment

日期:2015-01-19

Summary:

    Flux-cored welding material is a traditional sunrise industry, which has high production efficiency, good quality welding, arc stability, spatter, low overall cost, can be adjusted deposited metal composition and performance series of advantages.Compared with manual welding and solid wire, in the process, mechanical properties, weld appearance quality, etc. were dominant, and because you can always change the flux-cored wire alloy composition and powder formulations according to the material characteristics of various materials welded structures proportion to accommodate a variety of different materials welding requirements applicable to mechanical and manual automated and semi-automated, high-intensity time-scale production, more adaptable than other welding materials flexible manufacturing requirements, so cored wire is All welding materials are adapted to the widest range of welding materials. From a global perspective, flux cored wire in developing countries are the strong.

    Foreign market trends

    Flux cored rapid development of foreign countries, mainly the United States, Japan, South Korea and some countries of Europe (Germany, UK, France, Sweden, Norway, etc.), is currently in the United States flux-cored welding material proportion reached 35℅ the proportion of Japanese cored wire up 36℅, some European countries (Germany, Britain, France, Sweden, Norway, etc.) has reached more than 20℅. The proportion of developed countries welding materials (rod, wire, flux, etc.) are roughly as follows: wire (solid wire, cored wire) accounted for more than 65℅, submerged arc welding consumables (flux, wire) accounted for about 12℅, welding account 25℅ below. Our flux-cored welding materials in proportion only 15℅.

    Can be seen from Figure 5, the Japanese welding electrode material proportion of declining solid wire from rising but gradually decreased, flux cored steady increase year by year. Into the twenty-first century, the evolution and growth of China's industrial structure and rapid economic development in Japan have many similarities. From 1996 to 2008, the use of flux cored domestic annual growth rate (20℅ ~ 25℅), after China's production bottleneck breakthrough capability of flux cored wire and the industry acceptance of flux cored continuous improvement, etc. considerations, the use of domestic flux cored expected annual rate of increase will 30℅ of.

Forecast domestic production and application development of flux cored wire
     The popularity of flux cored wire and Japan, but also from the shipbuilding industry began, China's shipbuilding system has been proposed that in 2009 the main shipyard welding efficiency rate to reach more than 80%, of which the application rate of CO2 gas shielded welding 55 %, welding mechanization and automation rate of about 70%.
     Shipbuilding industry through the promotion of efficient welding technology has been used in the industry and submerged arc flux cored gas-shielded arc welding technology. China's shipbuilding industry in recent years is expected to continue growing, the annual growth rate is higher than in 30℅.

2.1 Expanding flux cored wire applications
     Two applications were cored wire expansion trends: First, the shipbuilding industry extends to marine engineering, machinery manufacturing, construction and bridges, steel, boiler from - tanks and other fields; the second is from large enterprises to small and medium enterprises to expand.
2.2 Continue to promote industrial restructuring and efficient welding

    China's industrial structure adjustment, the ship - offshore structures, oil - chemical industry, construction - a bridge industry, boiler - tank industry, vehicles - automobile, industrial machinery - electrical machinery industry are all focused on supporting industries, and these industries requires a large amount of welding material per year. In these industries, is currently working to promote efficient welding technology, thus providing a huge space for development of this highly efficient flux cored welding consumables, but also for the continued growth of flux cored wire usage provide a guarantee.

    In addition, trends in the use of welding materials from Japan, the flux-cored first applied in shipbuilding, ship and marine structures accounted for 70% of the flux-cored wire, buildings, bridges cored wire industry accounted for about 40% on average from the drug industry accounting for more than 60% of the core wire. Due to increased wire, high efficiency and automatic welding, robotic been developing rapidly.

 

    In recent years, with the progress of welding automation, intelligent and semi-automated, flux cored from the scale to expand varieties. MAG welding (CO2 gas shielded arc welding) is increasing rapidly year by year with flux cored wire production. At present, in addition to the general low-carbon steel 500Mpa grade high strength steel, again more steel cold steel, high-strength steel, stainless steel flux cored wire has been the object of a variety of products, we can imagine the future of welding material called "drug "

    Discussed above analysis shows that it is feasible to invest cored wire manufacturing.
