The “CanNeed-WWP-100 Welding Seam Ball Press Tester” is used to test the welding seam quality, including the welding seam strength and continuity of 3-piece cans.

Testing Method: place the empty cans to the clamp, align the welding seam with the ball, and then tightly press the can. The cylinder pushes the ball to slide along the welding seam. Next, take the can out to check if there are any breaches.
