Abstract
Disclosed is a temporary and mobile apparatus and methods for manufacturing welded products, including pressure vessels, wherein heating and/or cooling is to be applied to substrate material of the weld site. Certain embodiments include panels arranged to form a convection section that allows for improved heating and cooling of substrates and provide improved welding processes. Embodiments can include a manifold along used for heating and cooling. Apparatuses and methods of using making those apparatuses for improved welding are described herein.
