Abstract

The invention discloses a memory type welding electrode which comprises a welding core and a welding scale wrapping the welding core. The welding scale is prepared from, by weight, 22-55 parts of fluorite, 16-36 parts of ilmenite, 20-45 parts of magnetite, 12-36 parts of sepiolite, 5-18 parts of titanium-nickel alloy, 6-18 parts of batteriumalloy, 11.5-40.5 parts of iron-manganese alloy and 15-35 parts of plastic titanium resin. In this way, by means of the memory type welding electrode, the strength and toughness of a weld joint are improved, the memory performance of a weldment is improved, it is guaranteed that the weldment can still restore to the original shape when bearing impacts, and the performance stability of the weldment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a memory type welding electrode. 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] In the prior art, the strength and flexibility of the weld seam are not good during the welding process, and the weldment that completes the welding work is prone to bending and cracking when receiving impact, which affects the quality of the weldment. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a memory-type welding electrode, which improves the...
