The main objective of industries reveal with manufacturing better quality product at low cost and increase productivity. TIG welding is most vital and common operation use for joining of two similar or dissimilar parts with heating the material or applying the pressure by using the filler material for increasing productivity with less time and cost constrain. The TIG welding parameters are the ...

Spot welding is used extensively in the automotive industry. The quality of an individual welding spot is a major concern due to the heavy reliance on their use in the manufacture of cars. The main parameters that control the quality of a welding spot are current, voltage, welding force, welding time, and the quality of the welding electrodes. The condition of the welding electrodes plays a maj...

Resistance spot welding is an important and widely used method for joining metal objects. In this paper, various classification methods for identifying welding processes are evaluated. Using process identification, a similar process for a new welding experiment can be found among the previously run processes, and the process parameters leading to high-quality welding joints can be applied. With...

Numerous industrial applications, particularly those in the transport industry, require joining of dissimilar materials which offers considerable benefits terms low cost, design flexibility, and weight reduction for overall structures. The problems associated with conventional fusion welding processes have stimulated researchers recent years to develop new methods are difficult join. Friction s...

Laser welding has a large potential for the production of tailor welded blanks in the automotive industry, due to the low heat input and deep penetration. However, due to the small laser spot and melt pool, laser-based welding processes in general have a low tolerance for seam gaps. In this paper, five laserbased welding techniques are compared for their gap bridging capabilities: single-spot l...

Surface interaction at the worksheet/worksheet interface during resistance spot welding of aluminium alloy 5182 with spherical tip electrodes was investigated. Oxide layer cracking and nugget formation were focused. Both experimental work and finite element analysis were employed to explain the contact behaviour at this interface. It was found that sheet separation and thus bending occurred dur...
