A butt weld Joint is developed on steel plates having yield and ultimate tensile strength of 500 MPa and 700 MPa, respectively. The thickness of the plates is 8 mm and width is 20 mm. Improper selection of welding parameters caused an undercut of 3 mm depth along the weld. The maximum transverse tensile load (in kN) carrying capacity of the developed weld Joint is _________.
-
- 70 kN
- 71 kN
- 69 kN
- 72 kN
Correct Option: A
Pt = (st) (tunder cut) L
= 700 × 20 × (8 – 3)
= 700 × 100
= 70 kN
