By implementing a high‐speed welding system with a new arc welding robot, researchers have far exceeded current welding speeds. The heat warp of the work piece and adhesion of spatter onto the workpiece has been decreased, reducing the cycle time, and total heat input.

Interaction with robot systems for the specification of manufacturing tasks needs to be simple since the paper targets the widespread use of robots in small and medium enterprises (SMEs). In the best case, existing practices from manual work could be used, to ensure current employees a smooth introduction to robot technology as a natural part of their work. The aim of the paper is to simplify the robot‐programming task by allowing the user to simply make technical drawings on a sheet of paper. Craftsmen use paper and raw sketches for several situations: to share ideas, to get a better perspective of the problem, or to remember the customer situation. Currently these sketches have to be either interpreted by the worker when producing the final product by hand, or transferred into CAD files using an appropriate software tool. The former means that no automation is included, the latter means extra work and considerable experience in using the CAD tool.

The approach is to use a digital pen and paper, both based on the Anoto technology, as input devices for SME robotic tasks, thereby creating simpler and more user‐friendly alternatives for the programming, parameterization and commanding actions. To this end, the basic technology has been investigated and fully working prototypes have been developed to explore the possibilities in the context of typical SME applications. Based on the encouraging experimental results, it is believed that drawings on digital paper will, among other means of human‐robot interaction, play an important role in manufacturing SMEs in the future. Consequently, a fully working test‐case welding example is presented and explained, allowing a complete demonstration of all the developed features.

This paper explores the utilization of digital pens for the task of programming industrial robot manipulators, i.e. the possibility of obtaining robot programs from technical drawings on a sheet of paper. A practical implementation was presented to demonstrate how to use digital pens and CAD applications to program industrial robots. The results clearly show that the digital pen based on Anoto technology, integrated with CAD interfaces and code generation interfaces, is very useful and powerful for the planned task. The next steps will be to adopt a software infrastructure and develop the necessary services to allow system integrators to consider this type of device as an advanced user‐friendly robot‐programming method.

This is the first time that digital pens have been used to program robot manipulators.

The OKAZAKI plant of the Mitsubishi Motor Corporation started production in August 1977. The plant has adopted the latest layout which could not be developed without the concepts and manufacturing techniques accumulated for many years. Also it is equipped with a highly automated body assembly production line incorporating many industrial robots as one of the major facilities.

Examines the challenges facing the shipbuilding industry today and details the solution offered by a consortium of three German companies. It is based on the prefabrication of sub‐assemblies on production lines in which automation is critical to the economics. Describes welding robots playing a key role in this approach and the robot systems supplied to one German shipbuilder. Also important to cost effectiveness is a new high speed welding process that uses two wires in the weld torch, enabling productivity to be at least doubled. Another necessity is an off‐line programming and simulation system, specifically developed for the shipbuilding industry, that is typified by one‐off and low volume manufacture.

More than half of the industrial robots throughout the world are used in the automobile industry. The following deals with the most important application so far, spot welding in car‐body construction, and one with a promising future, namely, assembly.

Steel beam welding at a construction site is challenging due to the increasing thickness of steel members in today's buildings. In order to achieve high quality welding and resolve the problem caused by the shortage of skilled welders, robotic systems are in high demand. We have proposed a practical robotic system for steel beam welding, specifically designed for working on H‐shaped column structures that are known to be the most difficult structures for automation.

This paper aims to solve the problem that the changing of groove size and assembly gap would affect the precision of the multi-pass path planning and the welding quality and realize the automatic welding of a thick plate.

First, a double-sided double arc welding (DSAW) system with a self-designed passive vision sensor was established, then the image of the groove was captured and the characteristic parameters of groove were extracted by image processing. According to the welding parameters and the extracted geometry size, multi-pass path planning was executed by the DSAW system.

A DSAW system with a self-designed passive vision sensor was established which can realize the welding thick plate by double-sided double arc by two robots. The clear welding image of the groove was acquired, and an available image processing algorithm was proposed to accurately extract the characteristic parameters of the groove. According to the welding parameters and the extracted geometry size, multi-pass path planning can be executed by the DSAW system automatically.

Gas metal arc welding is used for root welding and filler passes in DSAW. Multi-pass path planning for thick plate by Double-sided Double Arc Welding (DSAW) based on vision sensor was proposed.

The purpose of this paper is to analyze the technology of capturing and processing weld images in real‐time, which is very important to the seam tracking and the weld quality control during the robotic gas tungsten arc welding (GTAW) process.

By analyzing some main parameters on the effect of image capturing, a passive vision sensor for welding robot was designed in order to capture clear and steady welding images. Based on the analysis of the characteristic of the welding images, a new improved Canny algorithm was proposed to detect the edges of seam and pool, and extract the seam and pool characteristic parameters. Finally, the image processing precision was verified by the random welding experiments.

It was found that the seam and pool images can be clearly acquired by using the passive vision system, and the welding image characteristic parameters were accurately extracted through processing. The experiment results show that the precision range of the image processing can be controlled about within ±0.169 mm, which can completely meet the requirement of real‐time seam tracking for welding robot.

This system will be applied to the industrial welding robot production during the GTAW process.

It is very important for the type of teaching‐playback robots with the passive vision that the real‐time images of seam and pool are acquired clearly and processed accurately during the robotic welding process, which helps determine follow‐up seam track and the control of welding quality.

This paper aims to improve the scene sense of a virtual scene, the welding model of a virtual reality system of riser automatic equipment was constructed using Unity3D and UG software, which mainly included a welding car, welding guide rail, welding power supply, virtual camera and other equipment and the model was rendered.

The human-computer interaction page and simulation test of the system was produced using the user interface GUI system for creating a human-computer interaction scene. The operator could capture the welding status of the physical equipment accurately and in real-time so the virtual reality technology was very suitable for the remote monitoring operation integrated with the welding system.

Human-computer interaction design and collision detection were realized. In addition, the system simulation experiment was accomplished. With the continuous improvement and development of virtual reality technology real-time virtual simulation and monitoring, technology will become the main development trend.

Based on virtual reality, the monitoring system can capture the operation status of physical welding equipment in real-time and accurately, which is very suitable for remote monitoring operation integrated with the welding system and also conducive to improving the monitoring level of the welding process.

This technology is time-saving and money-saving, for the operators do not have to be in a real welding environment and therefore they can get away from dangerous places. Consequently, it can avoid unnecessary injuries and problems.

This technology can replace people to enter the dangerous and extreme environment to carry out welding operation, so it becomes the most effective means of nuclear power plant maintenance, space structure construction and marine engineering construction. In addition, it is time-saving and money-saving.

With the rapid development of virtual reality technology in recent years, it is a new research direction to apply virtual reality technology to the remote welding operation. This technology is different from the traditional way of welding for the operators can stay away from the welding scene especially some dangerous places.
