Hello,
I'm trying to reproduce the same effect used in a video but I tried several tutorials and until now I wasn't able to find the correct way to do it. Could some one please suggest mea tutorial where I could learn how to do it?
The link for the video is: Coldwater Machine SpotMeld Refill Friction Stir Spot Welding - Aluminum Sheet to Aluminum Sheet - YouTube
The effect that I want to reproduce starts at 0:25 and it is the red effect. What I want to do is this change in the shape along the time.
Thanks in advance.
