Design and experimental verification of an intelligent wall-climbing welding robot system

Abstract

Purpose – This paper aims to present a new intelligent wall-climbing welding robot system for large-scale steel structure manufacture, which is composed of robot body, control system and welding system. Design/methodology/approach – The authors design the robot system according to application requirements, validate the design through simulation and experiments and use the robot in actual production. Findings – Experimental results show that the robot system satisfies the demands of automatic welding of large-scale ferromagnetic structure, which contributes much to on-site manufacturing of such structures. Practical implications – The robot can work with better quality and efficiency compared with manual welding and other semi-automatic welding devices, which can much improve large-scale steel structure manufacturing. Originality/value – The robot system is a novel solution for large-scale steel structures welding. There are three major advantages: the robot body with reliable adsorption ability, large payload capability and good mobility which meet the requirements of welding; the control system with good welding seam tracking accuracy and intelligent automatic welding ability; and friendly human – computer interface which makes the robot easy to use.

Tracked Wall-Climbing Robot for Calibration of Large Vertical Metal Tanks

“…Typically, the design of the adhesion and locomotion mechanisms, which determine the payload, moving velocity, and energy supply, vary according to the working conditions and working content. In a number of applications where the WCRs are designed for heavy work, such as rust-removal [3,20], wall cleaning [8,9,17], and automatic welding [4,21], the robots are optimized for high loads and high energy consumption to ensure the working progress. The locomotion and adhesion mechanisms of these robots could be large-sized and heavy, and a number of types of locomotion and adhesion mechanisms could even be combined to meet specific requirements.…”

“…Minghui Wu et al [8] focused on adhesion force and the mechanism for passing over obstacles for a wheel robot. The mechanism included lifting the body of the robot to avoid obstacles by varying adhesive forces.Zhongcheng Gui et al [9] developed a robot for welding with colossal load-carrying capacity and high adsorption reliability. They showcased an inchworm mechanism with two switchable magnets for adhesion.…”
