Joining of the similar & dissimilar materials alloys using heat friction in currently being used, especially for non-ferrous which are considered as non-weldable alloys. Al 2024-T6 6061-T6 having length 70mm and 12mm diameter were welded by welding process. Similar samples obtained applying different combinations parameters like pressure 30bar, forging from 50 to 60 bar, rotational speed 22...

Femtosecond (fs) laser irradiation has been shown to be effective for welding transparent materials and for transparent materials to metals. However, to date there is little work regarding similar applications in welding/bonding of metals. In this article, we for the first time to the best of our knowledge report on fs laser-induced microwelding of Ag microwires and Cu substrates. The influence...

Industrial applications often require welded joints of dissimilar metals to perform reliably under adverse working conditions. Such conditions demand high resistance failure modes, such as fatigue, corrosion, and creep. In involving intense vibrational cyclic loading conditions, strength-to-weight ratio metals, including aluminum, are more vulnerable fatigue failure. This study investigates the...

This paper emphasizes the need for occupational hygiene professionals to require evidence of the quality of welding fume data from analytical laboratories. The measurement of metals in welding fume using atomic spectrometric techniques is a complex analysis often requiring specialist digestion procedures. The results from a trial programme testing the proficiency of laboratories in the Workplac...

Electron beam welding has proved phenomenal in welding of components used in space because it uses a vacuum environment which eliminates substances like oxygen, nitrogen, and hydrogen. The main advantage of EBW is its ability to weld dissimilar materials and incorporate desirable properties in the assembly. It has high depth to width ratio and focuses exactly on the portion to be welded, thereb...

In order to achieve a high-quality joining of aluminum (Al) and copper (Cu) dissimilar metals, new friction stir double-riveting welding (FSDRW) with Cu rod as the rivet was proposed, rotating tool large concave angle shoulder specially designed. The results showed that under thermal–mechanical effect tool, deformed be double riveting heads structure anchor at upper surface Al plate an above la...

FSW material flow and phase transformation were studied at the interface of dissimilar welding of Al 6013 to Mg. Defect free butt weld was obtained when aluminum and magnesium test plates were placed in the advancing side and retreating side respectively, and the tool was placed 1 mm off the weld centerline into the aluminum side. In order to understand how the materials flow during FSW, steel ...

Mechanical properties of dissimilar weld joints between GOST09ch16N4B (a martensitic stainless steel) and AISI 4130 thin sheets made by gas tungsten arc welding (GTAW) were studied using ER410NiMo and ER100S-G filler metals in post weld heat treated conditions. Heat treatment cycles consisted of austenitization at 900, 950 and 1000 °C for 1 h and this was followed by oil cooling and tempering a...
