The improvement of the mandatory national standards system based on the European ECE automobile technical regulations has a great effect on improving the safety and environmental protection technology level of China's automotive products. The current implementation of the automotive product management system requires that domestic production of automobile and motorcycle products must be inspected by the national quality supervision and inspection center in compliance with relevant mandatory standards in order to organize production and sales. With the increase of mandatory inspection projects and the gradual approach of standard levels to similar international laws and regulations, through the continuous enhancement of production consistency requirements and the implementation of national quality supervision and spot checks, the development and introduction of new technologies and new products of production enterprises, and the construction of quality assurance systems have been promoted.
Strengthen the implementation of standards to standardize the production and sales of auto parts. Analyze the demand characteristics of the maintenance market and the types of auto parts and their applicable standards. First of all, safety components such as brake system components (brake linings, brake hoses, brake fluids, etc.), lamps, wheels, tires, glass, mirrors, wipers, etc. must comply with mandatory national standards. , also must match with the corresponding model, can not be produced and installed. This type of component is the focus of anti-counterfeiting. Apart from this, maintenance standards that do not directly affect safety performance are more difficult to unify, and generally can be tested according to the manufacturer's express standards. Some components, such as wearing parts, also have different levels of user requirements, and should allow low costs. The accessories are used for the maintenance of the market, and should not be used as the sole basis for judging the original company fittings, corporate standards, and recommended national and industry standards.
Strengthening the awareness of standards in all aspects of society has a positive effect on the anti-counterfeiting of auto parts, and we must further intensify the promotion and implementation of existing mandatory national standards. Manufacturers of auto parts manufacturers should establish product standards and meet the requirements of the corresponding national or industry standards, have the ability to ensure the consistency of production; auto users can not be free of charge and choose parts that may affect the performance and even safety performance, should choose the designated maintenance of the car manufacturer Stations or maintenance companies with certain qualifications and technical strength; maintenance companies should use accessories that meet relevant standards and be responsible for the quality of maintenance and be supervised by government agencies.
There is still a lot of work to be done in the perfection of the automotive standardization system. It is necessary to give full play to the role of all sectors of society. In the near future, it should also increase government departments' investment in standardization work. China's auto industry enterprises still have the problems of small scale, weak technological development capabilities, and low level of standardization of parts and components manufacturing enterprises. At the same time, due to factors such as technology foundation and government investment, the national and industry standards are revised. The cycle is relatively long, and the overall level still has a certain gap between international standards and the standards of the developed countries. We must learn more from the experience of developed countries and accelerate the transformation of international standards. The standardization system in many countries in the world is different from ours. The standard is basically civil behavior. Various types of civil organizations can formulate their own standards and recommend social use. (The US SAE standards and Japan's JASO standards with wide international influence are all established by civil society organizations. (car standards) actively participate in international standardization activities; and the government just stands by the public's position and adopts laws and regulations to force safety, environmental protection, and energy saving indicators of automotive products to comply with the requirements (China's mandatory standards are similar to this); Perfect product technology standards are sufficient to ensure that products meet the government's regulatory requirements and have market competitiveness.
All in all, the coordination and implementation of the management functions of government departments is still the most important basis for anti-counterfeiting of auto parts. The implementation of government management on the market access of auto parts in accordance with mandatory national standards and the strengthening of the management of maintenance companies can effectively combat the production and sales of fake and shoddy products. To promote automobile standardization as an important aspect of anti-counterfeiting work for auto parts, the National Automobile Standardization Technical Committee has the responsibility to cooperate with the work of government departments.
1.Welding materials
In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.
The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
