Aluminum cold extrusion process is at room temperature, by the press to mold metal blank at a constant speed exert strong pressure on the metal to plastic deformation extruded from the die cavity, to obtain the required shape and size and has a certain mechanical extrusion performance. "As gas water heater is working with the water, so most of its operating temperature between 110 degrees Celsius to 260 degrees Celsius. Hot state, annealing and quenching conditions forming the new performance is better than the heat treatment significantly enhanced the effect, but the heat treatment process demanding. This paper relies on this technique to study the structure and mechanical properties of the microstructure of thin-walled copper and aluminum pipe plug-in resistance pressure welding joint interface organization. Aluminum and aluminum alloy sheet can be tungsten or tungsten AC TIG pulse welding. Pattern aluminum strip in the cold rolling process, due to roll with conflict and rolling aluminum alloy surface, the surface will produce fine alumina powder and adsorption fall, rolling oil, and by the way the suspension components will be left in the aluminum surface, for Aluminum composite, coating and other products processing constitute bad influence. The project _ Tension straightening strip Because violent attack on a roll bending, tension is applied to convert a portion of the strip is the strip of oxidative stress tension roller press Flower aluminum professional production, and ends constitute a conflicting forces embossed aluminum oxide, femoral artery and rollers. Therefore embossed aluminum oxide professional manufacturers, if the strip surface without eradication, deformation of alumina powder fall, followed by oil with x appended tension the roller surface of the roller, the roller surface abrasion attack, and constitutes slightly hurt aluminum oxide embossed aluminum Which is good, it is necessary to eradicate eradication through specialized equipment, talented forward aluminum surface quality, with international quality standards with aluminum. oxidative stress Flowers specializing in the production of aluminum oxide embossed aluminum _ _ cis Alcoa (Views) provided by Jinan Heshun Aluminium Limited.
