在兄弟单位的帮助下,我们焊修东风型内燃机车柴油机机体裂纹采用了碳弧气刨铲裂纹坡口。经过实践证明,碳弧气刨铲坡口不但能保证焊修质量,而且能大幅度的提高工作效率,减轻工人劳动强度,缩短机车检修停时。过去用手锤、扁铲铲一个机体垂直板与水平板同时存在裂纹的双侧坡口,一个熟练的技术工人得工作12个小时。现在采用碳弧气刨,一个技术工人仅需30～50分钟即可质量较好地 With the help of our brother unit, we used the carbon arc gouging crack crack to crack the body of diesel engine of Dongfeng diesel locomotive. Practice has proved that carbon arc gouging shovel not only to ensure the quality of welding repair, but also significantly improve work efficiency, reduce labor intensity, shorten the locomotive maintenance time. In the past with a hand hammer, flat shovel shovel a body vertical plate and horizontal plate simultaneously crack the two sides of the groove, a skilled technical workers have to work 12 hours. Now using carbon arc gouging, a skilled worker only 30 to 50 minutes to better quality
