TL;DR: In this paper, the main investigation directions performed at the Department of Materials Technology and Welding are presented: Weldability of HSLA steel and factors influencing susceptibility to cold cracking of welded joints.
Abstract: Underwater Welding - A Review The paper describes principles of underwater welding and recent trends in research works undertaken for enhance welding technology and properties of underwater welds. Department of Materials Technology and Welding at Gdansk University of Technology (GUT) has been involved in underwater welding research for over 25 years. Investigations include technology of underwater welding, and weld properties examinations. All tests have been performed with the use of self designed stands allow to perform welds in shallow depths as well as the depths up to 1000 m. The main investigation directions performed at the Department of Materials Technology and Welding are presented: Weldability of HSLA steel and factors influencing susceptibility to cold cracking of welded joints. The effects of wet welding conditions on diffusible hydrogen amount in the welds. The effects of heat input, underwater welding depths and composition of shielded gases on welds toughness.

TL;DR: A review literature on mineralogy of clay minerals and phenomenon of swelling in oil and gas industry is presented in this paper, where unique ion exchange properties and clay swelling mechanisms are also considered.
Abstract: Among the minerals found in the earth's crust, clay minerals are of the widest interest. Due to the specific properties such as plasticity, absorbing and catalytic properties clay minerals are used in many industries (oil & gas, chemistry, pharmacy, refractory technology, ceramics etc.). In drilling, a phenomenon of swelling clays is frequently observed. It has an important impact on the cementing quality. During the last few decades clays have been the subject of research on a scale unprecedented in the history of mineralogy. This paper presents review literature on mineralogy of clay minerals and phenomenon of swelling in oil and gas industry. Unique ion exchange properties and clay swelling mechanisms are also considered.

TL;DR: In this article, the idea of the use of Temper Bead Welding (TBW) technique to improve the weldability of high strength steel at underwater wet welding conditions is described. But this method is not suitable for high-strength steel.
Abstract: The article presents the idea of the use of Temper Bead Welding (TBW) technique to improve the weldability of high strength steel at underwater wet welding conditions. Wet welding method with the use of covered electrodes is described. This work shows results of metallographic examinations and hardness measurements of samples of S420G2+M steel with weld beads performed under water. It has been shown that Temper Bead Welding technique may provide a way to reduce the hardness of the welds, thus is a useful method for improving weldability of high strength steel welded in underwater conditions. The optimum overlap of weld beads (pitch) was set of 55÷100%.

TL;DR: In this article, a multifunctional material which allows conducting of electrical current and simultaneously holds mechanical properties of a polymeric composite was proposed for exterior fuselage elements of an aircraft to minimize damage occurring during lightning strikes.
Abstract: Abstract The paper focuses on development of a multifunctional material which allows conducting of electrical current and simultaneously holds mechanical properties of a polymeric composite. Such material could be applied for exterior fuselage elements of an aircraft in order to minimize damage occurring during lightning strikes. The concept introduced in this paper is presented from the points of view of various scientific disciplines including materials science, chemistry, structural physics and mechanical engineering with a discussion on results achieved to-date and further plans of research.

TL;DR: In this article, the results of laboratory investigations made on the PU foams have been made, and they have shown anisotropic properties as measured in parallel and perpendicular direction to the foam rise, and three directional values of Poisson ratios in tension have been determined for foam of 62 kg/m density.
Abstract: The report presents results of laboratory investigations made on the PU foams Mechanical properties of foams have been measured in compression tests for two foams of 16 kg/m and 62 kg/m density, and in tension and shearing tests for foam of 62 kg/m density PU foams have shown anisotropic properties as measured in parallel and perpendicular direction to the foam rise Three directional values of Poisson’s ratios in tension have been determined for foam of 62 kg/m density The fatigue tests have been made for foam of 62 kg/m density, at 10,000 cycles of loading and unloading of mass cargo barge Reduction in buoyancy for both foams after 7 and 30 days of immersion in water has been shown to occur to some extent The burning tests were performed for foam of 62 kg/m density showing good behaviour
