Consumable Testing
Filler metal inspection checks the chemical and mechanical properties of welding materials before use. It ensures the materials meet the specified quality standards.
Physical-Chemical Mechanism of Action
Filler metal testing analyzes the chemical composition and mechanical properties of welding materials like wires, electrodes, and powders. It checks parameters such as hardness, tensile strength, ductility, and corrosion resistance.
Metallurgical Relevance & Welding Risks
Wrong filler metals can lead to insufficient hardness, excessive stress buildup, or poor ductility. This can cause cracking, wear, and a reduced service life of the weld. Missing testing can therefore lead to serious safety issues in service.
Workshop Practice & Instructions
Before welding materials are used, they must go through accredited filler metal testing. Inspectors check chemical composition and mechanical properties per ISO or DIN standards. If deviations from specified values occur, the material is rejected. It's important that all welding materials are tested regularly to ensure they meet the required quality standards.
