Fillet Weld Load Capacity
The strength of a fillet weld is proportional to the product of its size (s) and length (L). Since the design load must remain constant, the product $ s \times L $ must remain constant.
This leads to the relationship: $ s_1 \times L_1 = s_2 \times L_2 $
Determining Required Weld Length
Given values are:
- Initial weld size, $ s_1 = 5 $ mm
- Initial weld length, $ L_1 = 150 $ mm
- New weld size, $ s_2 = 6 $ mm
Substituting these values into the equation $ s_1 \times L_1 = s_2 \times L_2 $ and solving for $ L_2 $ determines the required length.
The required weld length is 120 mm.
