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.
Group of answer choices
- 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.
