Tailor Welded Blanks (TWB) are blanks in which two or more sheets of similar or dissimilar materials, thicknesses, coatings etc. are welded together to form a single sheet before forming.
Introduction In recent years, the consumer industry has been incorporating a variety of materials in its products made on a large scale to improve performance and reduce costs.
This has resulted in increased demands for techniques to weld dissimilar materials and for use in large scale industrial production [1–3].
Specific energy input to the material reduced and faster cooling rate can be achieved with increase of welding speed.

Polyvinylidene fluoride (PVDF) is one of the popular membrane materials due to its outstanding properties including thermal stability, chemical resistance and excellent mechanical strength and has been widely used for MD [2].
These properties coupled with its intrinsic hydrophobicity have made PVDF popular as a membrane material in many membrane processes such as membrane-based gas absorption, MD and other types of membrane contactor applications.
Materials and Methods Materials The materials that were used in this experiment were PVDF polymer (MW = 440,000 g/mol) was purchased from Sigma–Aldrich Chemical Co.
