Abstract

The invention relates to a surfactant for repairing H13 die steel cracks with low-power laser and a preparation method of the surfactant, aiming at solving the technical problems that the H13 die steel cracks repaired by low-power laser in the prior art can not be thoroughly welded when the cracks are deep, and the repairing operation is difficult. The surfactant is composed of SiO2, Cr2O3, TiO2, MnO2, ZrO2 and SrCl2. The preparation method of the surfactant comprises the steps of mixing SiO2, Cr2O3, TiO2, MnO2, ZrO2 and SrCl2 and performing ball milling. According to the surfactant, the welding process is effectively simplified, the welding production efficiency is improved, and the welding cost is reduced. The surfactant is applied to the welding field.

Description

technical field [0001] The invention relates to a surfactant used in repairing cracks of H13 mold steel with low-power laser. Background technique [0002] The working environment of the mold is harsh, and it is prone to fracture and damage during production. Due to the high cost of some molds, in order to reduce the production cost, the mold needs to be repaired by welding. The use of laser welding technology in mold repair to prolong mold life has the advantages of fast welding speed, small heat-affected zone, and good weld performance, but limited by laser power and cost, high-power laser equipment is expensive, and the cost of use and maintenance is high. , The mold repair cost is close to the manufacturing cost, which is difficult for small and medium-sized factories to bear. However, low-power laser welding is difficult to penetrate deep cracks and repair them. [0003] In the mid-1960s, the Ukrainian Barton Welding Institute took the lead in introducing the concept ...
