The quality of back chipping is not only in relation to the quality of final welding seam, but also the schedule and cost of the whole project.

清根质量好坏不仅关系到焊缝的最终质量，同时还影响工程的进度和成本。

Therefore, the law of welding seam back chipping was studied based on the newly developed automatic back chipping machine with a disk-type non-consumable electrode.

因此，本文基于新研制的非熔化盘式电极自动清根技术，对焊缝清根规律进行了研究。

The research of back chipping can be basis of processes planning and technology parameters optimization. Meanwhile, it will be a theory foundation for the subsequent welding.

清根规律的研究，不仅能够为工艺制定和优化清根工艺参数提供依据，也为后续焊接过程做好基础理论准备。

The company claims that if optical discs written with this process are stored in a location where they are kept from cracking or chipping the data can be read back years later perhaps even 1, 000 years later.
