2.2. Welded Connection Design

Try these first

1. 1.

   What type of weld is used to join two surfaces at a corner?

   Hint

   Think of a triangle shape where two pieces meet.

2. 2.

   What is the minimum throat thickness for a 6mm weld?

   Hint

   Use the formula for throat thickness.

3. 3.

   What type of weld is triangular in cross-section?

   • A) Butt Weld
   • B) Fillet Weld
   • C) Plug Weld

   Hint

   Remember the shape associated with each weld type.

4. 4.

   True or False: A butt weld assumes full-section strength when properly executed.

   • True
   • False

   Hint

   Think about how butt welds are applied.

5. 5.

   Given a design force of 30kN, determine the required weld length in a fillet if the allowable weld stress is 100MPa. Assume the effective throat thickness is 5mm.

   Hint

   Use the formula: Length = Force / (Stress * Thickness).

6. 6.

   If a butt weld has a width of 12mm and using a design load of 50kN, calculate the required throat thickness if the allowable weld stress is 120MPa.

   Hint

   Remember to convert and use units consistently.
