在机械制造中,清洗工艺是非常重要的,它直接影响产品的制造质量及使用可靠性。而目前国内有很多工厂对产品的清洗工艺不重视,尚未认识到其重要性。我厂曾对电弧碰焊件做过试验,证明经过严格清洗的构件比未经清洗的构件,焊接后抗拉强度提高17～22.5%,由此可见清洗的重要性。 In the machinery manufacturing, cleaning process is very important, it has a direct impact on product quality and reliability of use. At present, there are many factories in the country do not pay attention to the product cleaning process, has not yet recognized its importance. Our factory had tested the arc touch welding parts, proving that after rigorous cleaning of components than the unwashed components, the tensile strength after welding increased by 17 ~ 22.5%, which shows the importance of cleaning.
