EJOWELD® offers the possibility to join different materials (lightweight material / high strength steel) without any pre-treatment (cleaning, de-coating, pre-drilling).

The EJOWELD CFF® friction element
enables the joining of lightweight materials with ultra-high-strength
sheet metal and is therefore especially applicable for demanding joining
tasks in automotive structural parts. The large head with hollow lower
head and the different lengths of the element allow the joining of light
metal cover plates with ultra-high-strength steels in a broad
application range and without any pre-holes. Flange widths from 18 mm
are ideal for this friction element. This joining technology is
universally applicable, process-reliable and allows a great variety of
material thickness combinations.
Cover plate: light metal (150-320 N / mm²), thickness 1.0 - 4.0 mm;
Base plate: steel material (270-1.800 N / mm²), thickness 1.0 - 2.0 mm.
The SRE friction element is only half the size
of the well-known CFF element. The material displaced during the joining
process is conveyed under the head and shaped by the special drive bit.
Due to its geometry, the EJOWELD SRE® friction element is
the ideal joining element for narrow flanges from 13 mm width with small
head projections. The element is therefore predestined for the
application in door and roof areas as well as add-on parts. This joining
technology is particularly reliable and economical due to its low
weight and short cycle time.
Cover plate: light metal (150-320 N / mm²), thickness 1.0 - 2.0 mm;
Base plate: Steel material (600-1.800 N / mm²) Thickness 1.0 - 2.0 mm.
EJOT has extended the EJOWELD® technology portfolio with another friction element, the EJOWELD® REF. This joining element is hollow, geometrically based on the EJOWELD CFF® and enables the joining of aluminum or FRP plates on aluminum sheets. With the support of a gradually controlled process, joints which are optimized regarding the original materials are created. A special advantage is the option to use the new REF together with a CFF element in one equipment. The only requirement is a specially anvil adaptor and an additional feeder. By selecting an appropriate program and feeder, three different material combinations (Al/St, Al/Al, FRP/Al) can be joined using just one equipment.
EJOWELD® fastens hybrid components, in particular lightweight materials such as aluminium and advanced high-strength steel, with a robot-compatible friction element setting tool. For this innovative fastening process, the EJOWELD® Application Check is now available, which enables the user to make a general statement about the feasibility of the individual joining task. It is essential to distinguish which materials and thicknesses are to be used and which space is available.
