Filler Material Inspection
Filler material acceptance tests and certifies the chemical composition and mechanical properties of welding consumables to prevent unacceptable alloy deviations.
Physical-Chemical Mechanism of Action
Filler material verification involves checking the chemical composition of welding consumables to make sure they match the specified alloy ratios. This prevents unwanted metals or substances from getting into the final weld metal.
Metallurgical Relevance & Welding Risks
Bad alloy deviations can cause weak spots in the weld, like porosity, loss of strength, or toughness. This can lead to cracks and part failure.
Workshop Practice & Instructions
1. Chemical Analysis: Use special lab equipment to determine the chemical composition of welding consumables.
2. Mechanical Testing: Test mechanical properties like hardness and tensile strength per ISO standards.
3. Certification: Make sure all results meet the specified standards and document them accurately.
