Aluminum foam is usually used as the core of composite materials by combining it with dense materials, such as in Al foam core sandwich panels and Al-foam-filled tubes, owing to its low tensile and bending strengths. In this study, all-Al foam-filled tubes consisting of ADC12 Al-Si-Cu die-cast aluminum alloy foam and a dense A1050 commercially pure Al tube with metal bonding were fabricated by ...

J. Matusiak, J. Wyciślik, Institute of Welding, Gliwice, Poland The article presents the results of research into the fume and gas emission during MIG/MAG arc weld brazing. Investigations were conducted for hot dip coated steel sheets with zinc and zinc and iron alloy coatings. Steel grades of DX 54D Z 100 MBO and DX 54D ZF 100 RBO were used during research. ARC shielding gases applied were Ar ...

Evaluation of welding process such as metal inert gas welding and tungsten inert gas arc welding on tensile, bend and hardness properties of austenitic stainless steel SS347H(18Cr 10Ni 1Cb ), T22(21⁄4Cr Mo) and T91(9Cr 1Mo V) grades are studied. Tubes of 54 mm of outer diameter and 4 mm of wall thickness is used as a base material in the following combination SS347H VS T91 and T91 VS T22 is wel...

Abstract. It is possible to assess the thermal efficiency of welding shielding gases by means of the arc temperature field analysis. Since this approach opens a remarkable study field to assess different shielding gases, giving support for dealing with advantages and disadvantages of commercial gas mixtures, there is a research line under development, which goal is to find techniques to measure...

As one of techniques to improve a penetration depth in gas tungsten arc welding, it has been proposed that carbon dioxide is applied as shielding using double torch. Two types gases can flow independently the torch: inner and outer gas. The purpose this study was clarification behavior establish guideline for controlling oxygen contamination which affects toughness welded part formed by welding...

Conventionally, the quality of the weld is ascertained only after the welding has been completed through the use of NDT techniques. A lot of time, material and manpower is wasted before one comes to know about the soundness of the weld. These limitations can be overcome if the weld is continuously monitored in real time for the assessment of defects using appropriate NDE sensors. This paper hig...

Sedmak, Faculty of Mechanical Engineering, University of Belgrade, Belgrade, Serbia This paper presents the analysis of the influence of temperature on mechanic properties of the base material and welded joints made of high strength steel. The joints...

Tungsten Inert Gas welding (TIG) process is an important component in many industrial operations. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the influence of welding parameters like welding current, welding speed on strength of low carbon steel on AA1050 material during welding. A plan of experiments bas...

Tungsten inert gas (TIG) welding, also called as gas tungsten welding 1. (a) Schematic of TIG welding Process (b) Variety of tungsten electrodes. The activated TIG (ATIG) welding process mainly focuses on increasing the depth of penetration and the reduction in the width of weld bead has not been paid. Tungsten inert gas welding, TIG is widely applied in manufacturing process for different The ...
