Abstract

 Preview

ISO 14270:2016 specifies specimen dimensions and a testing procedure for mechanized peel testing of single spot, seam and embossed projection welds, in overlapping sheets, in any metallic material of thickness 0,5 mm to 3 mm, where the welds have a maximum diameter of 7√t (where t is the sheet thickness in mm).

For welds of diameter between 5√t and 7√t, the peel strength values obtained may be lower than expected when using the recommended test specimen dimensions because the test specimen width is designed for welds of diameter of 5√t or less.

The object of mechanized peel testing is to determine the peel strength that the test specimen can sustain.
