Methods for evaluating the weld quality of seam welds in aluminium and aluminium alloy extrusion
1 Scope
This standard specifies the room temperature inspection method for the weld quality of weld seam in aluminium and aluminium alloy extrusion.
This standard is applicable to the inspection of the weld quality of weld seam in aluminium and aluminium alloy extrusion (hereinafter referred to as "weld quality").
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 3246.2 Inspection method for structure of wrought aluminum and aluminum alloy products—Part 2: Inspection method for microstructure
GB/T 16865 Test pieces for tensile test for wrought aluminum and magnesium alloy products
3 Etching method
The test shall be conducted in accordance with those specified in GB/T 3246.2.
4 Fracture method
4.1 Method summery
The fracture test is carried out by applying force to the specimen weld seam in extrusion, which causes obvious bending deformation or fracture to the specimen. The weld quality of the weld seam in extrusion is judged according to whether the weld seam in extrusion is broken or the fracture conditions. This method is applicable to specimens in artificial aging state.
4.2 Test device
4.2.1 Test machine: hydraulic or mechanical pressure tester or universal material test machine.
