东继业介绍，这台设备的核心在于高度智能化的机器人协作系统。它整合了电脑编程、智能算法与精密 控制技术，由4把可移动的二氧化碳气体保护焊枪和智能机械手臂协同作业。操作人员只需在触摸屏上 轻点"开始"，机械臂便会自动抓取母材送入焊接舱，4把焊枪随即同步启动。它们犹如4位技术顶尖的焊 工，焊得稳、准、快，焊缝均匀美观，质量显著超越人工标准。同时，密闭焊接舱与强力排烟系统彻底 解决了烟尘困扰，让工人告别了以往恶劣的作业环境。 （文章来源：科技日报） 首台设备的成功仅是起点。今年，齐齐哈尔车辆段再次实现技术飞跃，推出了升级版自动焊机。新一代 设备在易用性和效率上再进一步，仅需一人即可操控，实现了从自动上料、精准定位、协同焊接到成品 出库的全流程无人化智能作业。这不仅极大降低了人工成本与劳动强度，更将生产效率推向了新高度。 记者近日走进我国最北端铁路货车检修基地——中国铁路哈尔滨局集团有限公司齐齐哈尔车辆段。在这 里，智能机器人成为检修主力：四只不知疲倦的"机械巧手"组成的高效"焊匠"，以远超人工的稳定性与 精准性，将单扇敞车下侧门的焊接时间从15分钟大幅压缩至仅3分钟，日焊修量从30扇飙升至120扇，效 率提升高达40 ...

Core Insights - The article highlights a significant technological advancement in the railway freight car maintenance sector, specifically through the introduction of automated welding technology at the Qiqihar Vehicle Section of China Railway Harbin Bureau Group [1][2]. Group 1: Technological Advancements - The introduction of a robotic welding system has drastically reduced the welding time for freight car doors from 15 minutes to just 3 minutes, resulting in a production increase from 30 to 120 doors per day, marking an efficiency improvement of 400% [1]. - The first automated welding machine for freight car side doors was developed after three months of intensive research, addressing previous challenges related to high costs and inefficiencies in manual welding [1][2]. Group 2: Operational Efficiency - The new welding system integrates advanced computer programming, intelligent algorithms, and precise control technology, allowing for simultaneous operation of multiple welding guns, which enhances the quality and speed of the welding process [2]. - The upgraded version of the automated welding machine, which requires only one operator, has further streamlined the process from automatic feeding to finished product output, significantly reducing labor costs and increasing production efficiency [2]. Group 3: Cost Savings and Impact - The implementation of the intelligent welding system has led to a substantial reduction in reliance on external procurement for freight car doors, saving approximately 5.9 million yuan in procurement costs within a year [2]. - The successful experience of this technology has been promoted for application across the entire railway network, indicating a broader impact on the industry [2].
