摘　　要：介绍耐磨堆焊在挖掘机斗齿、挖土机挖斗、装载机斗齿上的应用。通过对斗齿、挖斗进行耐磨堆焊，提高了其表面硬度和耐磨性，使基体具有高的韧性，大大提高了使用寿命。The application of abrasion resistant bead welding in bucket teeth of excavator、shovel bucket of excavator and bucket teeth of loader was presented. Through abrasion resistant bead welding of bucket teeth and shovel bucket,their surface hardness and abrasiveness as well as the toughness of the matrix were improved,therefore,the service life was increased.

关 键 词：耐磨堆焊 斗齿 挖斗 挖掘机
