我们车间主要生产1吨以上的大型铸件,由于铸造过程中铸件出现一些缺陷,有的缺陷既大又很复杂,铸件如果报废,会造成很大的经济损失。采用焊补方法进行修复,由于铸件大也会遇到很多困难。我们在生产实践中,坚持边干边学摸索其规律,使焊补技术不断提高,解决了一些大型铸件焊补的关键问题,现将焊补情况作简要介绍,供参考。 Our workshop mainly produces large castings of more than 1 ton. Due to some defects in the castings during the casting process, some defects are both large and complex. If castings are scrapped, great economic losses will be caused. Repair welding method, due to large castings will also encounter many difficulties. In production practice, we adhere to learning by doing while studying the law, so that welding technology continues to improve, to solve some of the key issues of welding of large castings, weld welding situation will now be briefly introduced for reference.
