Abstract
The invention provides a welding method using alloy powder as a welding filler. Based on an appropriate ratio, powder of at least five metal elements are mixed into high entropy alloy powder as the welding filler, and then the high entropy alloy powder is filled into a joining groove between two base materials. Continuously, the initial welding (root welding) is performed in the joining groove using an arc welding technique, and then the actions of filling the high entropy alloy powder and welding are repeatedly performed until a welding seam between the two base metals reaches a predeterminedlength and / or thickness. In the welding method, the high entropy alloy powder is composed of multiple alloy particles, and the size of the alloy particles is micron; and therefore, under the condition that the high entropy alloy powder is used as the welding filler, the welding seam formed between the two base materials has the characteristics of fine superfine structure, and specific strength, fracture resistance, tensile strength, corrosion resistance, oxidation resistance and the like are improved.
Description
technical field [0001] The invention relates to the related technical field of welding process, in particular to a welding method using alloy powder as welding filler. Background technique [0002] Welding is a process for permanently joining two base metals by applying heat to form an atom-to-atom bond between the surfaces of the two base materials. There are three ways to achieve welding: [0003] (1) Real welding: The base metal to be joined is heated to partially melt to form a molten pool, and the molten pool will solidify after cooling and then join the base metal to be joined. When necessary, the molten filler metal can be added to the molten pool when heating the base metal to achieve the best welding effect; [0004] and [0005] (3) Forging welding: first heat the two base metals to reach the incandescent state, and then use compression or vibration to join the two base metals to each other. [0006] Not all metal parts can be joined using the above welding met...
