Fillet Weld Leg size bigger than thickness of plate to be connected
(OP)
Hi guys,
First of all I want to thank this forum and people contributing to it in advance.
I do have a question about fillet welds that is bothering me quite a lot lately. If 2 plates are to be welded with each other in a T section form, assuming that both plates are 10mm thick, with 2 fillet welds, how would be the maximum leg-throat thickness of the fillet welds be determined. I am aware of the common rule that the throat thickness of the fillet weld should be roughly 0,707*minimum plate thickness. I am just in a position where the throat thickness of the fillet weld needs to be bigger than plate thickness due to fatigue reason. The American code states what the maximum throat should be, but in the newest version of the Eurocode it has been removed. It surely doesn't mmean that could use 100mm thick throat thickness. Right? Obviously this is related to heating temperature, heated zone and etc etc, but from a designer point of view, how could we determine the absolute maximum fillet weld size?
Thanks in advance

At some point there is no reason to increase the weld beyond what you need for strength.
The T- 1/16" rule is only for welds on the edge of plates, not on the sides.

Good point. Although......I've never been 100% certain what constitutes being close to a "edge"......so I've always observed the T- 1/16" rule.

I always thought it was to avoid "burn through" on the base material.
