Title:
HOUSING WITH A ROTATIONAL FRICTION WELDING SEAM
Document Type and Number:
WIPO Patent Application WO/2014/127996
Kind Code:
A3
Abstract:
The invention relates to a housing (10) which has a first part (14) with a first wall (22) and with an outer wall surface (28) and a second part (18) with a second wall (24) and with an inner wall surface (30). The wall surfaces can have for example a cylindrical casing shape at least in some sections. Portions of the first wall (22) and the second wall (24) overlap in an overlap region (26). The first wall (22) and the second wall (24) are connected along the circumference of the wall surfaces (28, 30) by means of a rotational friction welding seam (32) arranged in the overlap region (26). The rotational friction welding seam (32) has a compact zone (48) with a first elastic modulus and a mixing zone (44) with a different second elastic modulus.
