A welding fixture for size fixing a hollow element (F), e.g. a sealing frame, comprising a first fixture member (20a) having a first and a second engagement surface and a second fixture member (20b) having a first and a second engagement surface. The welding fixture further comprises a compression unit (40) arranged to fixate the first fixture member (20a) aligned with and spaced apart from the second fixture member (20b), such that the engagement surfaces of the first fixture member (20a) and the engagement members of the second fixture member (20b) are facing each other and are configured to exert a clamping effect on said hollow element. Each fixture element (20a, 20b) comprises a first and a second counter surface defining the maximum expansion of said hollow element (F) during use. |
