The welding process commonly used for fabricating tailor-welded blanks of dissimilar thickness for automotive applications is

1. gas welding
2. laser welding
3. arc welding
4. friction welding

Correct answer: laser welding

Solution

Laser welding is preferred for fabricating tailor-welded blanks of dissimilar thickness because it provides precise control over the heat input, allowing for minimal distortion and the ability to join different materials effectively.
