Technical Difficulty: Tailored Blanks

Two different materials in different thickness joint together

Tailored Blanks are different material, like steel, aluminum alloy, different thickness and different coating joining together by laser welding, then deep drawing or stamping.

Advantages:

˜The process helps that the right material could be used in the right place to reduce weight.

˜High quality and cost material used only in the necessary area.

˜Improve crash performance.

˜Scrap reduction by nesting optimized for various shapes.

˜Corrosion prevention and anti- rust.

˜Better accuracy and tolerance, stamping and assembly processes reduced, which helps quality control for different components, the semi-finished and finished part, no need subsequent processing.

Automotive Industry application:

Tailored Blanks are increasingly and widely used in the automotive industry. like

Reinforcement and overlapping joints for vehicle body parts, like side panels, side doors, side members, frames, A pillars, B pillars, C pillars, cross rail bumpers.

As tool maker, for the tailor blanks, full factors should be considered from initial design, simulation, technical study to machining, assembly, tuning and try out.

Designer consider drawing and forming for different strains in different areas of product.

The tailored welding blanks consisting of sheets in different thickness, material flow, strength and coating. The weld line possible cause concerns, like wrinkle, thinning or splitting.

For tailored blank process, basically two different material and thickness, and more than two materials, three, four, five varieties are on the way.
