Magnesium welding consumable
Magnesium welding filler is a special filler material for magnesium joining processes, processed under controlled shielding gas atmosphere. It helps reduce specific weight and improves mechanical properties.
Physicochemical Mechanism of Action
Magnesium filler metal contains chemical elements that affect how magnesium behaves during welding. For example, it can contain deoxidizers to prevent porosity, and metals like aluminum or silicon to increase strength and toughness.
Metallurgical Relevance & Welding Risks
Incorrect handling of magnesium filler metal can cause porosity and reduced mechanical properties. Insufficient deoxidation can prevent the metal from drying out properly and create pores. Too much alloying metal can impair the strength and toughness of the structure.
Workshop Practice & Instructions
Always use magnesium filler metal under a controlled shielding gas atmosphere, like helium or argon. Make sure the amount of filler is correct and the coverage is sufficient to coat all metal surfaces. Set the temperature so the filler dries completely and bonds well with the magnesium.
