Guided bend test jig

Date 03-23-2004 19:02

Design a wrap around fixture* for aluminum weld specimens. While it may take more gray-matter on your part to design and build, it can also be used for steel alloys. Keep in mind different radii may be required for different material groups and tensile strengths.

*A plunger type does not work well for heat-treated aluminum/aluminum alloys. The specimens will "kink" where the heat treating has been affected (decreased) at the area adjacent to the weld (HAZ).

p.s.: The dimensions for the fixtures are in the AWS structural codes.

I "think" the one DGXL is referring to is in AWS D1.1:2002, Figure 4.16-Alternative Wraparound Guided Bend Test Jig. The dims are based upon the specified or actual base metal yield strength in ksi.

I don't have a copy of AWS D1.2 that deals with structural aluminum, so you may want to check there to see if the jig is any different than the one specified for in the D1.1 structural steel code.

a Hossfeld bender can be modified to do the bend tests if you don't want to have to build a whole bender.
