High entropy alloy material for welding and application

The invention discloses a high entropy alloy material for welding and a welding method of the high entropy alloy material, and relates to the field of welding materials. The high entropy alloy material comprises Cr, Mn, Fe, Co and Ni; the invention further discloses the method for welding metal using the Cr-Mn-Fe-Co-Ni high entropy alloy material, and the method comprises the steps of base metal preparation, welding preparation, welding and post processing. The Cr-Mn-Fe-Co-Ni high entropy alloy material has strong 'diffusion retarding effect' and 'high entropy effect' in the high temperature condition, friability intermetallic compound generated in the welding area can be effectively avoided, the mechanical property of a welded structure is improved, the alloy cost is low, shapes of welding materials can be suitable for the requirements of complex varied welded joint appearance, the applicability is wide, and using is convenient and effective. 本发明公开了一种用于焊接的高熵合金材料及其焊接方法，涉及焊接材料领域，包括Cr、Mn、Fe、Co、Ni元素；本发明还公开了一种使用该
