method to determine the fillet weld size
method to determine the fillet weld size
(OP)
Hello all,
There is a guide, table or method to determine the fillet weld size in a structure subjected to cyclic stresses?
Frequently for static structure I use the table for min and max size of the AISC.
Is this a good method to determine this size?
thanks in advance.

Those types of tables are not a good way to design welds. Welds are designed as a function of the loads imposed upon them, the weld metal tensile, yield and shear yield stresses, and upon the strength of the base metals. Those mins. and maxs. in fillet size have to due with welding process, heat input to make a good weld, to much heat for thinner piece, ability to actually fit the weld to the pl, edge without melting nicks into that edge/upper corner, etc. The min. weld forces a large enough weld to cause sufficient heat input to allow the weld process to take place without cooling so quickly that cracking takes place or no real fusion takes place. The max. size pays attention to how large a weld the thinner pl. can tolerate, heat input, deformation, etc.; and it also recognizes that you can’t really get a full .5" fillet on the edge of a .5" pl. without a bunch of potential problems or extra work.

You need to design the welds to withstand the operational forces the joints see in service, have a look at this site: http://www.roymech.co.uk/Useful_Tables/Form/Weld_s...
