Description Many new, or relatively new, welding processes such as friction stir welding, resistance spot welding and laser welding are being increasingly adopted to replace or improve on traditional welding techniques.
The high usage of Al and its alloys in both the automotive and aerospace industries is attributed to its excellent specific strength and corrosion resistance. High demand of Al usage has led to the improvement of both the casting techniques and joining processes, in order to improve on the quality of the final product.
The selection of the manufacturing process for Al and its alloys is based on the capabilities of the specified requirements for components and the alloy used. High pressure die casting HPDC is the most widely used casting process in the automotive industry due to its high production rate, and ability to produce complex shaped components.
However, HPDC is prone to porosity making it difficult to heat treat and weld.
Semi solid metal SSM forming has the potential to produce near-net-shape components with high integrity. A high continuous wave Nd: Plates in the as cast, T4 and T6 heat treatment conditions which had passed radiography inspection were then laser welded.
Some of the initial as-cast plates that were welded were subjected to pre or post weld T4 or T6 heat treatment and are referred to as pre-weld T4 or pre-weld T6 and post-weld T4 or post-weld T6 specimens. Kunene, G. Mechanical properties of laser welded semi-solid metal cast A alloy.
University of Cape Town.Jul 07, · In this work, the effect of arc welding on microstructures and mechanical properties of industrial low carbon steel ( wt. % C) was studied. This steel is used for making gas storage cylinders. In order to realize the objective, optical microscopy, EBSD, X-ray diffraction, and hardness tests were used.
Different zones and some phases are identified. Investigation into properties of laser welded similar and dissimilar steel joints G. c;am, c;.

TRANSMISSION WELDING OF GLASSES BY FEMTOSECOND LASER: STRUCTURAL AND MECHANICAL PROPERTIES Paper M Panjawat Kongsuwan, Y.
Lawrence Yao Columbia University, New York, NY, , USA Abstract Femtosecond laser pulses were focused on the interface of two glass specimens.
Proper use of optical and laser processing parameters enables transmission. brational sample magnetometry was used for characterizing magnetic properties. Texture evolution during laser weld - ing of AISI stainless steel was also studied and a correlation was made between texture evolution and magnetic properties of the welded samples.
The effects of welding cycle on the mechanical properties of the laser welds in. Drawn part is characterised by a place with a large strain, while forming process simulation did not confirm the creation of crack using the TWB consisting of dual phase HCTX instead of previous HCT steel.
It is because HCTX steel has higher strength and lower ductile properties. Mechanical properties of high-power CO2 laser-welded joints of ultrafine-grained high-strength steel.
