Abstract

Purpose

To review presentations on assembly and joining given at a seminar, “The changing face of robotics: inside and outside the factory”, organised by the UK Institution of Electrical Engineers.

Design/methodology/approach

Details are given of three presentations. The first is by Dr Phil Webb of the University of Nottingham, who described a project to develop a flexible robotic cell capable of riveting and assembling aero‐structure components, in which a new method of “simulation‐based control” evolved. In the second, Pearl Agjakwa of Nottingham University and Craig Johnson of Rolls Royce talked about shape metal deposition, a process by which layers of weld are deposited by robot to form complex aerospace components with minimal tooling and short lead times. The final presentation was by Dr Wolfgang Kölbl of Meta Vision Systems on laser vision robot guidance. Applications in automotive and a new cross vision sensor were described, the latter being applicable to hole location such as for drilling and riveting.

Findings

Robotics inside the factory is extending into new areas of assembly and fastening and is now finding applications in the aerospace industry and not just in automotive.

Originality/value

Provides a review of some new assembly‐related process developments in robotics.

Abstract

Purpose

This paper aims to provide details of vision-assisted robotic welding technologies and their applications.

Design/methodology/approach

Following a short introduction, this paper first considers the background of vision-assisted robotic welding, the functions of the vision systems and the scenarios where the technology is of benefit. The main section provides examples of vision-assisted welding applications, together with details of the systems and products employed. Finally, brief concluding comments are drawn.

Findings

This shows that modern machine vision technologies, often based on lasers, can allow robotic welding systems to compensate for dimensional variations and errors, eliminate the need for complex and costly welding fixtures and act as an alternative to skilled human welders. This technology allows robotic automation to be deployed in welding applications where it was hitherto impossible, technically difficult or not cost-effective.

Originality/value

By considering a section of applications, this paper provides an insight into how machine vision technologies can enhance the capabilities of robotic welding systems.

Abstract

Purpose

The control of weld penetration in gas tungsten arc welding (GTAW) is required for a “teach and playback” robot to overcome the gap variation in the welding process. This paper aims to investigate this subject.

Design/methodology/approach

This paper presents a robotic system based on the real‐time vision measurement. The primary objective has been to demonstrate the feasibility of using vision‐based image processing to measure the seam gap in real‐time and adjust welding current and wire‐feed rate to realize the penetration control during the robot‐welding process.

Findings

The paper finds that vision‐based measurement of the seam gap can be used in the welding robot, in real‐time, to control weld penetration. It helps the “teach and playback” robot to adjust the welding procedures according to the gap variation.

Research limitations/implications

The system requires that the seam edges can be accurately identified using a correlation method.

Practical implications

The system is applicable to storage tank welding of a rocket.

Originality/value

The control algorithm based on the knowledge base has been set up for continuous GTAW. A novel visual image analysis method has been developed in the study for a welding robot.
