The actual thickness of butt weld as compared to the thickness of plate is usually A. More B. Less C. Equal D. None of the above

The correct answer is: B. Less.

A butt weld is a type of weld where two pieces of metal are joined together by

melting the edges of the pieces and then fusing them together. The actual thickness of the butt weld is usually less than the thickness of the plate, because some of the material is lost during the welding process.

Option A is incorrect because the actual thickness of the butt weld is usually less than the thickness of the plate.

Option C is incorrect because the actual thickness of the butt weld is usually less than the thickness of the plate.

Option D is incorrect because the actual thickness of the butt weld is usually less than the thickness of the plate.
