- Weld bend test: This test involves bending a welded metal sample to evaluate its ductility and resistance to cracking and deformation. It can be done using an arbor press or a testing machine with appropriate tools.
- Tensile test: This test measures the strength and elasticity of a weld joint by applying a pulling force until the sample breaks. A testing machine can be used to apply the force and measure the maximum load the weld can withstand.
- Charpy impact test: This test assesses the toughness and impact resistance of a weld by striking it with a swinging pendulum or a falling weight. A machine specifically designed for Charpy impact testing is commonly used.
- Hardness test: This test measures the hardness of a weld, which can indirectly indicate its strength and integrity. It can be done using a portable hardness tester or a static hardness testing machine.
- Macro etch test: This test examines the structure and weld penetration of a joint by etching the sample with a chemical solution. The resulting macroscopic features can be assessed visually or with magnification tools.
- Visual inspection: This is a common non-destructive test where a trained inspector visually examines the weld for issues such as weld discontinuities, porosity, cracks, or incomplete fusion. No special equipment is needed for this test.
Common test for intro welders that uses any convenient means of applying the force may be used , such as arbor press, a testing machine, or a hammer blow.
