It’s generated by the template logged-in.php, which in Kakumei looks like:

<p class="login">

<?php printf(__('Welcome, %1$s'), bb_get_profile_link(bb_get_current_user_info( 'name' )));?>

<?php bb_admin_link( 'before= | ' );?>

| <?php bb_logout_link(); ?>

</p>

So you’d want bb_get_profile_link(bb_get_current_user_info( 'name' ))
