# A plate 100 mm wide and 10 mm thick is to be welded with another plate by means of transverse welds at the ends. If the plates are subjected to a load of 70 kN, find the size of weld for static load The permissible tensile stress should not exceed 70 MPa.

Question-AnswerCategory: Strength of MaterialsA plate 100 mm wide and 10 mm thick is to be welded with another plate by means of transverse welds at the ends. If the plates are subjected to a load of 70 kN, find the size of weld for static load The permissible tensile stress should not exceed 70 MPa.

A plate 100 mm wide and 10 mm thick is to be welded with another plate by means of transverse welds at the ends. If the plates are subjected to a load of 70 kN, find the size of weld for static load The permissible tensile stress should not exceed 70 MPa.

Step: 1

Given Data
Width of the plate, w=100mm
The thickness of the plate, t=10 mm
permissible tensile stress = 70 MPa
Transverse filled welds =1.5

Step: 2

The maximum load which the plates can carry for billets welds
P = 1.414 × s × l × τ
70000 = 1.414×10×l×70
70000 = 989.1×L
L=70.7142 mm
Weld design: In order to allow for static and stopping of the load is 12.5 mm should be added to the length
L = 70.7142+12.5 = 83.21 mm
Hence the size of the weld is 83.21 mm
