Although aluminum and aluminum welding process will encounter many difficulties factor, but other materials such as copper compared to aluminum and aluminum also has some of the unparalleled advantage. So in the aviation, aerospace, automotive, machinery, electronics, chemicals, light industry, railways, etc., aluminum and aluminum alloy welding products are gaining widespread application manufacturer specialized in producing aluminum 7075, China's vast land Shandong 7075 aluminum supplier aluminum tubes resources are very rich in Jinan 7075 suppliers, and the development and utilization of low cost, aluminum and aluminum alloy welding in our country is very promising. Porthole design is too large (especially for low profile extrusion ratio), so squeeze pressure is reduced, thereby reducing the welding force. Recommendation from the edge of the vent hole extrusion cylinder wall at least 6-10mm distance. Shunt hole course selection and diversion structure of the bridge would be better considered together. 2. welding chamber volume is too shallow or too small, can not form a sufficient hydrostatic pressure. Reasonable under guarantee core rigidity and strength of the premise, to increase the volume of welding chamber. Welding chamber can be increased cross-sectional area, may also increase the height of the welding chamber. 7075 aluminum factory in Shandong, 7075 aluminum, aluminum rolls provided by the Aluminum Co., Ltd.
