In the paper, a modular climbing-wall mobile robot with four magnetic wheels is presented. It can move on the vertical steel wall and inspect the weld seam. First, the structure of the mobile robot is analyzed. It is modular, which consists of a light manipulator module, an ultrasonic probes module and a weld testing sensors module. Then, the magnetic wheels are designed and analysed. One magne...

An analysis is given for the mechanical characteristics of multilayer elastomeric isolation bearings where the reinforcing elements-normally steel plates-are replaced by a fiber reinforcement. The fiber-reinforced isolator, in contrast to the steel-reinforced isolator (which is assumed to be rigid both in extension and flexure), is assumed to be flexible in extension, but completely without fle...

structural steels with very high strength levels are often referred to as ultrahigh-strength steels (uhss). the usage of uhss has been extensively studied in aerospace industries and offshore platforms. in this study, medium carbon low alloy steel (ams6305) was thermomechanicaly treated to obtain an ultra-high strength bainitic steel for aircraft engine compressor disk. a novel themomechanical ...

This paper describes research towards the development of a robotic system for the automated inspection of steel plates. Such plates are inspected extensively during manufacture and fabrication. This inspection is often carried out manually in hazardous environments by skilled personnel. Such difficult conditions may reduce the operating ability of technicians, leading to poor performance and lo...

Abstract The need to manufacture lightweight structures from ultra-high-strength steels is forcing industry look for new joining technologies. Hybrid joints are one of the ways join materials. This paper investigates ultra-high strength steel plates using laser welding and adhesive bonding. Steel used in this was abrasion resistant (AR600) with tensile (Rm) ≥ 2 GPa. Three different epoxy adhesi...
