what is the different between steel and aluminum in bending test

Solution

1.aluminum alloys and aluminum welds aren\'t as ductile as steels. For this reason, the bend radius required for aluminum alloy bend tests usually is larger than that required for steel samples.

2.weld in steels normally is about the same strength as the surrounding material, while in aluminum alloys, the weld and the adjacent heat-affected zone usually are much weaker than the surrounding material.

3.A bend test is a more discriminating way to test your aluminum weld. Almost all welding codes require bend tests for welding procedures and welder qualifications. These tests can cause more problems in aluminum than in steel.

4.ny lack of fusion in the weld, no matter how small, will make the sample snap on bending. When a sample snaps, don\'t blame the welding wire or the parent material; a defect almost certainly is in the weld.
