. We found that an average total heating time of 4 to 4½ minutes (240-270 seconds) is a good, relatively conservative estimate. For this simple calculation, we recommend that you ignore the cooling part of the welded profile

. This test results in the first row of bonds create a peeling action on the next row of bonds throughout the duration of the test. The shear height is actively controlled during the test using an intelligent loadtool landing and stepback system and the fixturing allows for sample planarity and co planarity adjustment
