A beam$-$to$-$column connection by fillet welding. Q$355$ steel, E$50$ electrodes for manual welding, f$\_$f$^$w$=200$N$$mm$^2.$ The weld leg size for the flange is hf $1=8$mm$,$ for the web hf $2=6$mm$.$ The bending moment at the weld section is M$=120$kN$$m$,$ the shear force is V$=120$kN$.$ To check the fillet weld strength. $($no need to consider the effect of the beginning and ending of welding$)$
