In recent years, the whole world except China aluminum processing with an annual growth rate of about 30% growth outside the 6082 alloy aluminum supply manufacturers, all other countries aluminum processing steel production has maintained growth in the United States, Japan, Germany and other aluminum processing countries represented, aluminum processing industry in the late 20th century has been basically completed the integration process of survival of the fittest, mergers and acquisitions, and the establishment of a multinational company, and globalization of production and management; the most typical companies, including almost all the tubes processing wood species in each major region of the world with offices in aluminum processing timber capacity of nearly 2 million t; and in Japan, Germany, 6082 aluminum processing enterprises on behalf aluminum alloy distributors, to lead the world toward aluminum processing sophisticated direction, the beverage cans PS version of the base plate and premium and other development and production in the world leading level Overall, the development trend of the next few years the world's aluminum processing industry are: the number and size of enterprises do not have much change, productivity and production will not be much growth, and will continue to increase product variety, product quality will be more excellence, higher value-added products, and more specifically the energy saving: In aluminum processing, the in a more refined direction; in the aluminum 6082 alloy aluminum processing equipment suppliers, toward the intelligent direction; in the enterprise build toward the big and strong, and the fine and the direction of the vent hole irrational, shunt Bridge. and processing unreasonable. Should try to make the weld to the corners or decorative surface by, and using drip-shaped shunt bridge and reasonable welding angle, so that solder fell on top of welding chamber plane (ie preforming region); the use of "+ yu "bridge structural arrangement porthole, such as this case, the intermediate bridge can be narrower, and Shen bridge (darken parts of welding chamber depth) 5-8mm.
