GB 5293-85 Carbon Steel Arc Welding Electrodes
The Chinese standard GB 5293-85 Carbon Steel Arc Welding Electrodes is the national standard referenced in China and all others countries using the same standard, which regulates the makeup and use of carbon steel arc welding electrodes.
The main content of the standard include: welding practice and procedure, electrical characteristics, welding material, mechanical properties, dimensions, packaging, printing and marking and product inspection. With regard to welding practice and procedure, it includes welding conditions, joint design and preparation, weld reinforcement, deposit of weld layer and post-weld treatments. In terms of electrical characteristics, it covers weldability requirements and ratings, welding current ranges and melting temperature ranges. As for welding material, it specifies the chemical composition, mechanical properties and microstructure requirements of the carbon steel electrodes. Dimensions, thickness and length, weight, core and coating area, coating layer requirements, packaging, printing and marking requirements and product inspection regulations are all provided by the standard as well.
In order to ensure the performance and quality of carbon steel arc welding electrodes, GB 5293-85 strictly regulates the welding practice and welding procedure, electrical characteristics and welding material applied, as well as the packing, printing and marking and products’ inspection requirements. All of the above regulations are set in GB 5293-85 Carbon Steel Arc Welding Electrodes for reference purposes and for ensuring the best welding performance possible.
