<div>Hi, Hugh</div>
<div>As Vance says, HY80 is somewhat challenging to weld – err, actually, that’s
an understatement. We had to work with our fabricators to come up with a whole
weld procedure to satisfy our classing agency. If you decide to go this route,
let me know and we will share that procedure.</div>
