All aluminum body after the repair process

[Alcoa.com] Many people are researching the aluminum body on the body of a car because its quality is much lighter than that of a traditional body. The reduction in vehicle weight, fuel consumption will be reduced accordingly, and the relative pollution to the atmosphere will also be reduced, it can be said to make a certain contribution to environmental protection. This is one of the advantages of aluminum alloys, and its disadvantages are also there, one of which is the trouble of the post-invasion repair process.

Aluminum Body Repair Hardware Requirements

1、Aluminum body special gas shielded welding machine and profile repair machine

Because aluminum has a low melting point and is easily deformed, welding requires a low current, so a dedicated aluminum body gas shielded welder must be used. The prosthetic machine cannot be click-stretched like an ordinary prosthetic machine. Only the special aluminum auto-body prosthetic machine can be used to weld meson nails and use a meso-stretcher to stretch.

2, explosion-proof dust collection system

In the process of grinding aluminum body, it will produce a lot of aluminum powder, aluminum powder is not only harmful to human body, but also flammable and explosive, so there must be anti-explosive dust collection and dust collection system to absorb aluminum powder in time.

3, independent maintenance space

Due to the strict requirements of the aluminum body repair process to ensure the quality of vehicle maintenance and maintenance operations, to avoid aluminum powder pollution and explosion on the workshop, a separate aluminum body maintenance station should be established. In addition, the aluminum body maintenance personnel should carry out professional training, master the maintenance of aluminum body repair process, how to locate the tensile, welding, riveting, bonding and so on.

Maintenance considerations

1, aluminum alloy sheet local tensile is not good, easy to crack

If the engine hood inner plate is relatively complex, the high-strength aluminum alloy is used to improve its tensile deformation performance during the manufacture of the vehicle body, and the elongation rate has exceeded 30%. Therefore, it is necessary to ensure that the shape is not abruptly changed in order to avoid the occurrence of maintenance. crack.

2, the dimensional accuracy is not easy to grasp, rebound is difficult to control

In the maintenance, the method of releasing the stress by heating at a low temperature should be adopted as far as possible so that it will not be subject to secondary deformation such as rebound.

3, to ensure that the parts are intact

Because aluminum is softer than steel, it can cause defects such as bumps and scratches on the surface of parts due to collisions and various dust attachments during maintenance. Therefore, mold cleaning, equipment cleaning, dust and air pollution to the environment must be performed. Take corresponding measures to ensure that the parts are in good condition.

Double Handles Bathroom Faucet

1. Copper body: As far as the faucet is concerned, copper has long become the preferred material, mainly because the antibacterial effect of copper media has long been recognized by authoritative laboratories. Most high-end bathroom brands use copper as the body of the faucet, and the elimination of other materials has become an inevitable trend.
2. Electroplating: The quality of the electroplating surface is the most intuitive expression of the quality of the faucet. The surface plating is mainly nickel and chromium, so that it achieves a smooth and bright effect. Good quality faucets will undergo many tests, such as salt spray test, water test test, gas test test, etc., to ensure the durability of the faucet. After high-precision plating faucet, durability is basic, and more importantly, its surface gloss is good and comfortable to handle. Some high-grade faucets have other different treatment techniques, such as stainless steel and satin.
3. Filter screen: In areas where the water quality is not superior, the installation of the filter screen can reduce and filter impurities, and at the same time prevent the possible damage caused by impurities to the ceramic valve core. There are two installation locations for the filter: the water inlet and the spout.
4. Rotation angle: can rotate 180 degrees to make the work convenient, and can rotate 360 degrees is only meaningful for a sink placed in the center of the house.
5. Can lengthen the shower head: increase the effective radius, increase more functional possibilities, and the sink and container can be filled faster. In order not to make unpleasant noises, metal pipes should be avoided as much as possible.
6. Water pipe length: Experience shows that 50 cm long pipes are enough, and pipes of 70 cm or more can also be bought on the market.
7. Anti-calcification system: calcium will be deposited in both the shower head and the automatic cleaning system, and the same situation will occur on the faucet, where silicon will accumulate. The integrated air cleaner has an anti-calcification system that prevents calcification of the device internally.
8. Anti-backflow system: This system prevents dirty water from being sucked into the clean water pipe, which is composed of layers of materials. Devices equipped with an anti-backflow system will display the DVGM pass mark on the surface of the package.
9. Material: Stainless steel is hygienic and environmentally friendly. Chromium devices are easy to care for and harmless to people, but other elements need to be added to the manufacturing process. Therefore, it must be paid attention to what materials the equipment is made of, and not all countries have such high standards as Germany.
10. Durability: The anti-calcification system can protect the equipment from the danger of water leakage and handle damage.
