一、齿轮堆焊和淬火齿轮缺齿、顶部折断,在用氧-乙炔焰堆焊、淬火时,可用湿黄泥堆在相邻的三个齿上,以防止相邻的齿被退火和飞溅污染。二、气化器的焊接气化器是锌合金铸件,熔点约400℃。在采用氧-乙炔焰进行焊补时,除露出施焊部分外,气化器的其余部分埋在湿泥堆里。好处是,在焊补时金属 First, gear surfacing and quenching gear teeth missing, the top of the broken, with oxygen - acetylene flame welding, quenching, available wet yellow mud piles on the adjacent three teeth to prevent the adjacent teeth are annealed and splash Pollution. Second, the gasifier gasifier is a zinc alloy casting, melting point of about 400 ℃. In the use of oxygen - acetylene flame welding repair, in addition to exposing the welding part, the rest of the gasifier buried in the wet mud pile. The advantage is that when welding is done, metal is used
