What is that welder putting into the weld? Is it a backing pad? Is it effective?

It’s not about taking photos; welding hasn’t been done yet – it’s just a preparatory step
If it’s TIG welding, he should be applying tape to seal in the gas. Ensures welding quality in a high argon environment.
Keywords: gasket, rather than seal
Ensure the height of the internal weld metal and the quality of welding, while preventing drafts from affecting the welding quality. The surface of the gasket material is similar to aluminum foil
The gasket is made of ceramic, while the aluminum foil functions like tape, serving to bond and secure things in place.
