Aluminum Tube Pipe production process problems
Aluminum alloy in the production process, prone to shrinkage, trachoma, stomata and slag and other casting defects. How to repair aluminum alloy stamping holes and other defects?
If the welding, argon welding equipment to repair, due to heat, easy to produce thermal deformation and other side effects, can not meet the welding requirements.
Aluminum tube manufacturers analysis, cold welding repair machine is the use of high-frequency spark instantaneous discharge, no thermal welding principle to repair casting defects. As the cold heat affected area is small, will not cause the substrate annealing deformation, no cracks, no hard spots, hardening phenomenon. And welding strength is high, the material and the matrix at the same time after melting and then solidification, combined with a solid, can be grinding, milling, filing and other processing, dense does not fall off.
Cold welding repair machine is to repair aluminum alloy stomata, trachoma and other small defects of the ideal method.
Aluminum Tube Pipe company, if the use of the most advanced laser cladding technology, due to the small heat input, welding heat affected zone significantly reduced, and the grain is small, so the joint strength is high. At the same time, due to the laser welding process is stable, easy to adjust the power, making laser repair as the latest advantages of repair means.
Aluminum tube surface treatment methods generally exist anodic oxidation, electrophoresis coating and powder coating three kinds of treatment, each way has its own advantages, occupy a considerable market share.
Powder coating has the following advantages:
1, the process is relatively simple, mainly due to the production process of the main equipment to improve the accuracy of the main technical parameters have been able to achieve microcomputer control, effectively reduce the difficulty of process operation, while greatly reduce the auxiliary equipment;
2, Aluminum Tube Pipe high yield, under normal circumstances, if the measures properly, can maximize the control of nonconforming product production;
3, the energy consumption is significantly reduced, in the ordinary anodizing, electrophoretic coating production process, water, electricity consumption is quite large, especially in the oxidation process. Rectifier output current can reach between 8000 ~ 11000A, the voltage between 15 ~ 17.5V, coupled with the machine's own heat, need to keep using circulating water for cooling, tons of power consumption is often around 1000 degrees, While the reduction of ancillary facilities can also reduce some of the power consumption;
4, the degree of pollution of water, the atmosphere to reduce the alkali, sulfuric acid and other liquid organic solvents are no longer used to reduce water and air pollution, but also effectively improve the aluminum and environmental protection products as the competitive strength of steel profiles, accordingly Reduced some production costs;
5, aluminum workers of the labor intensity was significantly reduced, due to the use of automated assembly line operations, feeding methods and the use of fixtures has been significantly simplified, improve production efficiency, but also reduce labor intensity;
6, the quality requirements of the surface of the wool material has significantly reduced, the powder coating and can completely cover the profile of the extrusion pattern, cover a part of the aluminum surface defects, improve the surface quality of aluminum products;
7, Aluminum Tube Pipe coating some of the physical indicators than other surface treatment film has improved significantly, such as hardness, wear resistance, can effectively extend the life of aluminum.
