智能化和自动化技术在造船焊接中的应用(英文)

Intelligent automation used to improve ship welding

造船焊接中,焊接工艺需要优化以提高产量,同时,满足焊接标准的质量要求。然而,既使最成熟的焊接工艺,焊工所焊接操作等在其焊接准备阶段也无法“尽善尽美”。讨论了在焊前、焊中、焊后如何使用新型自动焊接设备,以减少工艺的不确定性。减少不确定性就意味着高水平的生产和质量。智能传感技术已应用于自动化程度不同的焊接设备中,如机械化、自动化机械设备和机器人,因其柔性化和轻便化而用于多任务的自动化焊接。并给出了应用实例。

No where in manufacturing is the old axiom of ＂Do the job right the first time＂ more true than in the welding operations in a shipyard. The welding process needs to be optimized to achieve high productivity while maintaining quality levels required by stringent welding standards. However, even with the most fine-tuned process, the welder or welding machine operator can be ＂done in＂ by upstream operations where the material is prepared to be welded. This paper discusses how new welding automation equipment can be utilized before, during and after the weld is made to reduce overall variability in the process. Reduced variability results in a higher level of productivity and quality. Intelligent sensors have been combined with different levels of automation including mechanized, machine and robots to facilitate flexible and portable automation capable of multi-tasking processing.Several practical examples of realistic and effective systems in production making money and improving quality.
