Recently, a domestic high-end tool manufacturing enterprise announced a major technological breakthrough in the field of laser-welded diamond saw blades. The newly developed laser-welded diamond saw blade has been specially optimized for cutting hard materials such as reinforced concrete walls and roads. As a core product for concrete cutting, this saw blade adopts high-precision laser welding technology, which effectively enhances the bonding strength between the diamond segments and the base. During continuous cutting operations on reinforced concrete, compared with traditional sintered circular saw blades, its service life is extended by more than 50%, and the cutting efficiency is increased by 30%. It is worth mentioning that the product can also be used in conjunction with diamond grinding cup wheels for subsequent grinding work after concrete cutting, forming a one-stop construction solution. Industry insiders said that this technological breakthrough will further promote the upgrading of domestic concrete cutting tools and provide strong support for improving the quality and efficiency of infrastructure construction.
