Dear Sir,
Option A has a throat thickness of 8,0 mm
Option B only has a throat thickness of 4,9 mm (excess weld metal doesn’t do anything regarding strength calculation)
Option C has a throat thickness of 7,0 mm
Option D: throat thickness depends on the degree of concavity but in general this will be less than 3 mm so in that case it will be equal to or larger than 8 mm
In general I would say option A or D, this depends on how much concavity option D will have. In case concavity will be less than 3 mm option D will be the strongest. Beside that option D will also be the preferred weld detail in case your construction will be under dynamic load, for avoiding stress risers in order to prevent any fatigue issues.
Met vriendelijke groeten / Best Regards,

Onderwerp: [MW:20830] Regarding fillet weld
Dear Experts,
Please advise me which of the fillet weld joint is strongest (assuming they are all made using the same material and welded using the same WPS) ?
A 8 mm throat of a mitre fillet
B 7 mm leg + 2 mm excess weld metal
C mitre fillet with 10mm leg
D concave fillet with 11mm leg
Thanks and Regards
Pavankumar Reddy
