检测工作是生产的主要环节之一,对确保产品质量,有效利用材料,和改进工艺都很重要。这不仅能提高生产率,而且对降低成本,节约材料和使用安全都有实际的作用。过去和现在往往采用抽查方法,选取试件进行破坏试验。试件不合格时,就把全批产品报废,所以损失很大。因而,应开展无损检测技术的研究,以新的工具和新的方法,逐个检测产品,无损地鉴定共质量。 Testing is one of the main aspects of production, and it is important to ensure product quality, make efficient use of materials, and improve processes. This not only increases productivity, but it also has a real impact on cost reduction, material savings and operational safety. In the past and nowadays, the spot check method is often adopted and the test pieces are selected to carry out the sabotage test. Specimens failed, put the full range of products scrapped, so a great loss. Therefore, non-destructive testing should be carried out research, new tools and new methods, one by one testing the product, non-destructive identification of total quality.
