Tig Welding Restarts on Steel
TIG > Stainless Steel • 4m 54s
Whether TIG welding, Mig Welding, Stick welding, or any other process, Restarts are part of the process. If you can make a decent restart, you are a lot less likely to have weld defects and a lot more likely to make a good looking weld.
What is the 3 second rule?
The 3 second rule says that it should take 3 seconds or less to get moving when you restart a weld bead.
For stainless steels, it might be even better to use a 2 second rule.
