The welding process commonly used for fabricating tailor-welded blanks of dissimilar thickness for automotive applications is
Show Hint
When you see "tailor-welded blanks" or "automotive sheet metal joining," immediately think of high-energy density processes like Laser Beam Welding for its precision, speed, and low distortion.

- arc welding
- laser welding
- gas welding
- friction welding
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Understand the Product. Tailor-Welded Blanks (TWB) consist of sheets of different thicknesses or grades welded together before stamping.
Step 2: Evaluate Requirements. The weld must be high-strength and narrow so it doesn't crack during deep drawing.
Step 3: Select Process. Laser Beam Welding (LBW) is preferred because it has a very high energy density, creates a very narrow Heat Affected Zone (HAZ), and results in minimal thermal distortion.

During a welding operation, thermal power of 2500 W is incident normally on a metallic surface. As shown in the figure below (figure is NOT to scale), the heated area is circular. Out of the incident power, 85% of the power is absorbed within a circle of radius 5 mm while 65% is absorbed within an inner concentric circle of radius 3 mm. The power density in the shaded area is _________ W mm^-2 (rounded off to 2 decimal places).
