Abstract

The invention discloses a smokeless environment-friendly welding rod which comprises a welding core and a welding scale wrapping the welding core. The welding scale is prepared from, by weight, 22.5-66.5 parts of rutile, 11-22 parts of ferromanganese, 15-36 parts of magnesium-aluminum alloy, 20-36 parts of quartz, 21-42 parts of folium artemisiae argyi, 23-45 parts of ephedra sinica, 13-48 parts of centella and 28-46 parts of binder. In this way, by means of the smokeless environment-friendly welding rod, weld joints can be cleaned, it is avoided that a large amount of smoke is generated in the welding process, meanwhile, the attractive weld joints can be formed, the quality of the weld joints can be improved, and the welding environment can be optimized.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a smokeless and environment-friendly welding rod. Background technique [0002] The welding rod is a metal strip that is melted and filled at the joint of the welding workpiece during gas welding or electric welding. It is composed of two parts: the coating and the welding core. The coating decomposes and melts during the welding process to form gas and slag, which play the role of mechanical protection, metallurgical treatment, and improvement of process performance. [0003] At present, relatively large smoke is often produced in the welding process, which will affect the working environment of welding and cause injury to welding workers. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a smokeless environment-friendly welding rod, which can purify the welding seam, avoid generating a large amount of smok...
