How long are my ASME weld tickets good for?

They expire 6 months from the date of issue. If a weld is struck under a government permit on either one of these tickets using the process of TIG AND Stick the expiry date for all of the ASME tickets you hold are extended for 6 months. If a weld is struck under a government permit using only one process the expiry date for that ticket only is extended for 6 months.
