“…It mainly includes the autonomous guidance of initial welding position [1], welding seam tracking [2,3], optimization of welding parameters during the welding process [4,5], and automatic localization of the finish point of the weld seam. As one of the key issues, welding seam tracking aims at online adjustment of the position of the heat source with respect to the seam to ensure a right welding position.…”

Extensive industrial use of thick highstrength steel plates in Arctic shipbuilding calls for submerged arc welding (SAW) processes with higher deposition rates. One of the most effective ways of increasing the deposition rate is to increase the number of welding wires. Although SAW processes with up to six wires exist, their use is not widespread and two-or three-wire modifications, which are the focus of this paper, are the most common approaches. This paper presents a case study of the development of a welding procedure for welding of high-strength steel shipbuilding plates using a three-wire SAW process. Welding parameters and conditions were evaluated with the aim of achieving a high-quality weld. Optimal parameters for 12-mm plate thickness were found to be: Св-08ГСМТ wire (similar to Mn4Ni1Mo) of 3.2 mm in diameter, single-pass welding, welding flux 48AF-56, I = 840 A, U =37 V, Q = 5.4 kJ/mm. Optimal parameters were also found for 16-mm plate for two pass welding. Testing of the weld joint included a static tensile strength test, an impact energy test at different temperatures, a bending test, a low-cycle fatigue strength test, microstructure examination and a hardness test. The tests showed satisfactory results that indicate that the developed welding technique is applicable for Arctic shipbuilding applications. The paper provides improved understanding of the welding technique selection process for Arctic shipbuilding as well as providing industrially valuable information about the developed welding technique.

The work studies the main problems of automation of processes of multi-pass MIG/MAG welding of large-dimension parts in all spatial positions under conditions of low repeatability of assembly operations. Necessity is shown and, at the same time, insufficiency of application of only laser-television sensor for adapting purpose. A procedure was proposed for equipping a robot-technical (mechanized) welding complex with the computer vision means such as a system of laser-television and video-pyrometric sensors. The results of development of technical means, algorithmic and software support of adaptive welding complex are presented. Proposed control algorithms use the results of on-line measurement of geometry parameters of preparation of butt joint groove as well as position of molten pool. It is shown that the adaptive robotic system performes all the basic functions, typical for it, namely adjustment of electrode position and parameters of welding mode under disturbing factor conditions, and is capable to provide necessary geometry and mechanical characteristics of the weld. As an example, this work uses a robotic complex of ABB company, including welding robot ABB IRB-1600, equipped with laser-television and video-pyrometric sensors, and arc power source ESAB Aristo MIG 5000I. The welding experiments showed that the developed software and hardware allow adapting robotic technical complex for application in welding of butt joints under effect of disturbing factors such as gap size change, distortion of electrode wire, ambient temperature change etc. 8 Ref., 6 Figures.
