Weld Example $2$

Example $14-3$

Using $50$ksi steel and E$70$ electrodes, design SMAW fillet welds to resist a full$-$capacity load on the $\frac{3}{8}6-$in member shown in Fig. $14\mathrm{.}13.$

Weld Example $2$

Tension member $($from before$)$:

$P_n=F_y{A}_g$

${}_t{P}_n={}_t{F}_y{A}_g,$ with ${}_t=0\mathrm{.}9$

Weld Example $2$

Weld strength $=0\mathrm{.}6F_{E}Lxt$

Rearrange to:

$L$ required $=$ required weld strength

$L$ required $=P\frac{u}{0\mathrm{.}6F_{E}t}$
