Do you still need to weld in sequence if your part is tacked? You bet you do, and this time there's proof.

Last video, I skipped the tacks on purpose so you could watch the weld move. Some of you guys called out to just tack instead of welding in the first place. So here's round two: two identical 90s, tacked the same, welded in opposite order, and then in the proper weld sequence. How will these two corners do?

Post your sequencing method and tag us. I'd love to see it.
