Abstract
A tube weld seam test method and device for testing a tube weld seam (32) of a flexible tube (18) for leaks having: a first pinching device (10) and a second pinching device (12) for pinching closed the flexible tube (18) at a first position (A) and at a second position (B), the weld seam to be tested being arranged between the first and second positions (A; B); a compressing mechanism arranged for partly compressing a tube section enclosed between the first and second pinching devices (10; 12); and a pressure test device (14) arranged for testing an internal pressure of said tube section in order to test the tube weld seam for leaks.

A tube weld seam test device for testing a tube weld seam (32) of a flexible tube (18) for leaks, comprising:
- a first pinching device (10) and a second pinching device (12) for pinching closed the flexible tube (18) at a first position (A) and at a second position (B) distant from the first position (A);
- a compressing mechanism (26) arranged for partly compressing a tube section enclosed between the first and second pinching devices (10;
- 12), when the tube (18) is pinched closed by the first and second pinching devices (10;
- 12);
- and
- a pressure test device (14) arranged for testing an internal pressure of said tube section.
A method of testing a weld seam (32) of a flexible tube (18) for leaks, comprising:
- pinching closed the flexible tube (18) at a first position (A) and at a second position (B), the tube weld seam (32) to be tested being located between the first and second positions (A;
- B);
- partly compressing a tube section between the first and second positions (A;
- B);
- and
- testing an internal pressure of the tube section.
