核结构退役需要具有成本效益的远程操作自动切割技术。使用固态激光器进行切割，采用光纤传输数千瓦范围内的激光功率，并具有高光束聚焦能力，使单个激光源能够处理多种类型的加工应用。高价值资产，即激光器本身，可以放置在远离切割的安全清洁区域并进行维护，从而使系统可以重复用于其他几种退役应用。那么问题是将切割头部署到远程结构上。本文描述了一种由永磁粘附爬墙机器人部署的 5kW 激光切割系统，该机器人开发用于携带由重 19 kg 的激光切割头、提供电源和控制信号的光纤电缆组成的有效载荷。厚度不超过 40 毫米的钢板可以以 50 毫米/分钟的速度切割，而 10 毫米厚的钢板可以以 800 毫米/分钟的速度切割。
Decommissioning of nuclear structures requires cost effective remotely operated automated cutting techniques. Cutting with solid-state lasers employing optical fibre delivery of laser power in the multi-kilowatt range and with high focus ability of the beam offers the capability of a single laser source to address more than one type of process application. The high value asset, which is the laser itself, can be situated and maintained in a safe clean area, remote from the cutting, thus allowing the system to be reused for several other decommissioning applications. The problem then is to deploy the cutting head on the remote structure. This paper describes a 5kW laser cutting system deployed by a permanent magnet adhesion wall climbing robot developed to carry the payload comprising of the laser cutting head weighing 19 kg, optical fibre cables supplying power and control signals. Steel plates up to 40 mm thickness can be cut at speeds of 50 mm/min while 10 mm thick plates can be cut at greater speeds of 800 mm/min.
