Final answer:
In the context of welding, the '___ time' is the postflow time, which refers to how long the shielding gas continues to flow after the welding arc is stopped, protecting the weld and electrode from contamination.
Step-by-step explanation:
The ___ time you're referring to is the postflow time. This is a term used in welding, particularly Gas Tungsten Arc Welding (GTAW) and Gas Metal Arc Welding (GMAW). The postflow time refers to the length of time the shielding gas continues to flow after the arc is stopped, covering the molten weld and electrode from atmospheric contamination. The exact duration can be adjusted based on the equipment used and the specific welding task at hand
