Welding method of wear resistant overlaying layer and wear resistant material for use therein

摘要

PURPOSE:To manufacture wear resistant material of the highest level by the general purpose welding method. CONSTITUTION:Cladding by welding is performed on iron-based base metal M by using a MIG (metal inert gas arc) welding machine. A component of a wire 30 used for welding is made to a matrix of a cladding layer L. A fixed quantity of sintered hard alloy granules G are added to a molten pool P during welding. The particle size of the granules G is made to be 0.5-3.0mm and the granules are dispersed equally into the matrix at the ratio of 30-70 weight % for the whole cladding layer. Since material of the matrix is selected from metals in the wide range by using MIG welding machines spreaded all over the country, the country, resistant material most suited for wearing conditions can be easily manufactured.
