The authors of this experimental research work have made an attempt to experimentally investigate the ultimate flexural load of ferrocement slabs of size 700mm. X 200mm. X 15mm. (thickness) reinforced with PVC coated steel weld mesh, and compare the results with slabs using GI-coated steel weld mesh, by varying the number of layers from 1-3. Ordinary Portland Cement, locally available river san...

-S 169 WELDING JOURNAL ABSTRACT. A 3-D transient numerical model was developed for simulation of gas metal arc (GMA) weld pools with free surface and droplet impact effects. This effort predicted a moving GMA weld pool by considering not only the heat transfer and fluid flow driven by surface tension gradient, electromagnetic force, buoyancy, and arc pressure, but also detailed information abou...

the absence of merchants played a significant role in the movement of national oil industry and had undeniable effects on the failure of this movement in 1953. the focus of this study is to find out the reasons why merchants were absent in the great oil national movement. in this study, document analysis was used to respond to the research question. the finding shows that the merchants especial...

The joining of a 6-mm thickness Al 6061 to AISI 1018 steel has been performed by the combined effects of fusion and solid state welding. The process is derived from friction stir welding (FSW) but with an adjustable offset of the probe location with respect to the butt line. Metallographic studies by optical microscopy, electron probe microscopy, and the utilization of the X-ray diffraction tec...

Friction stir welding (FSW) is an innovative process that has been successfully used in joining aluminum alloys, normally difficult to weld. Important advantages over fusion welding are better retention of baseline material properties, lower residual stresses and excellent mechanical properties. Defects that occur in FSW joints are due to improper tooling or setup. Non-destructive techniques us...

It is very well known that the use of robotics in the industry increases productivity and quality in many aspects. It is also well known that some adjustments have to be made to grant payback for the investment and to reach the expected results. Today, the robotization is known as an alternate technique for production, increasing qualitative and quantitative competence of its industries. One po...

This paper introduces a carriage-type welding robot which is to implement into double hull assembly line in shipbuilding. The developed robot consists of 5-axis carriage-type body, a controller, and a welding power supply and is capable of welding fully automatically such as a commercial industrial robot system without any interruption by an operator in a cell which consists of vertical weld-li...

Quality of welded joint at MAG welding process depends of numbers of influences, like type and thickness of base metal, groove type, welding position etc., but the proper selection of welding parameters is also very important. Due to that, the analysis of weld bead geometry at MAG welding process with regard to weld current, voltage and weld speed (heat input) and the type and shielding gas flo...
