If you enable Query Strings then change the redirect like this
redirect('c=welcome &m=index', 'refresh');
Additionally it may required to write index.php? or only ? before c
Or if change configuation in config.php then you need change the c and m
like
$config['enable_query_strings'] = FALSE;
$config['controller_trigger'] = 'c';
$config['function_trigger'] = 'm';
