No Gap ! No Groove ! How is Perfect Penetration Tig Welding Possible ? 

Hello everyone.
Is it possible to obtain a uniform back bead even when there is no gap between stainless steel pipes without beveling?
I'm going to show you this today.
Perhaps this method is not commonly applied to actual welding work. There are many advantages, but there are also many disadvantages.
But I don't think it would be a bad idea to learn these principles.
Later on, I will show you how to apply this method to a wider variety of situations.
Thanks for watching and have a nice week.
