back chipping

基本解释

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。
A welding backing with sand mould has been invented to realize welding penetration, which fully takes the place of gouging back chipping which has all kinds of shortcomings and disadvantages.
研究发明的“背衬砂垫焊接工艺”能够非常容易地实现焊透的目的，可以完全取代落后的碳弧气刨清根工艺，克服了目前常用的碳弧气刨清根所带来的缺点、弊病和不足。

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.
