Three mm thick plates of commercial pure copper were welded via friction stir welding method using a floating bobbin tool. The effect of different process variables such as the tool transverse speed and the tool rotation speed were examined in order to create a weld with the desired properties. A defect-free weld was obtained at a rotation speed of 1400 rpm and a transverse speed of 18 mm/min w...

STATEMENT OF PROBLEM The fracture of complete denture is a common occurrence in the field of prosthodontics. Often if all other criteria are met such as good aesthetics, occlusion, and functionality; denture repair is acceptable. Once denture fractures, we would want the joint surface strength to be as good as original. PURPOSE The purpose of this study was to determine the effect of differen...

There are a wide range of important applications for metal tube materials in various fields. The production process of high-frequency longitudinally welded pipe includes first using a roller to coil the long steel strips of a certain size into a cylinder shape, and then join them by heating the steel materials at the welding edge with a high-frequency welding machine — Fig. 1. The processes inc...

This paper presents a novel approach to welding thick steel plates that offers time and energy savings compared with conventional techniques. The combination of gas metal arc (GMAW) hot-wire technology simplifies the joint configuration enhances process tolerance. In this study, square butt was prepared as-cut edges thickness 15 mm. relationship between current deposition rate solo GMAW showed ...

The purpose of this work was to join and assess the development of solid state joints of dissimilar material AA6082 aluminum alloy and AISI 304 stainless steel, via continuous drive friction welding process, which combines the heat generated from friction between two surfaces and plastic deformation. Tests were conducted with different welding process parameters. The results were analyzed by me...

The present study is directed to the temperature and residual stress fields in hardfacing remanufacturing for a large-scale grinding roller with damage. For this purpose, numerical procedure process based on thermal cycle curve method was established, effectiveness of proposed verified by measurements multi-pass welding experiment V-groove butt joint. A local model bead-on-plate used check heat...

The article presents the results of an analysis surface roughness parameters, microhardness, and stresses layer ofFSW butt joints subjected to burnishing process with a diamond tip. This can be useful in selecting optimal parameters process, ensuring best properties FSW joint. Burnishing force feed rate influence were analyzed according two-factor three-level full factorial statistical complete...
