Frequently Asked Questions (FAQs)
What are the welding gas requirements for ERTi-2 welding wire?
To ensure optimal performance during welding, it is recommended to use pure argon gas (Ar) with a flow rate of 10-15 L/min. Pure argon effectively prevents oxidation, ensuring clean welds and quality.
What welding methods are suitable for ERTi-2 welding wire?
ERTi-2 welding wire is widely used in TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding methods. With excellent welding performance, it is suitable for precision welding and large-scale automated welding, providing strong weld joints while effectively controlling the heat-affected zone to prevent cracking.
How does ERTi-2 welding wire compare to stainless steel welding wire?
Compared to stainless steel welding wire, ERTi-2 welding wire has superior corrosion resistance, especially in environments with chlorides, nitric acid, and other corrosive media. With a density of approximately 4.5 g/cm³, it is 40% lighter than stainless steel, reducing structural load, and contains no iron or impurities, making it more suitable for high-purity welding.
Which base materials is ERTi-2 welding wire compatible with?
ERTi-2 welding wire is particularly suitable for titanium and titanium alloy base materials such as CP-Ti (Grade 1, Grade 2) and titanium alloys. It is also compatible with welded joints involving titanium-stainless steel and titanium-aluminum alloys, providing good compatibility and mechanical performance.
How can welding defects be avoided during the process?
Ensure cleanliness: Clean the base material surface before welding to remove oil, oxide scale, and other contaminants. Control heat input: Maintain appropriate welding current and voltage to avoid overheating. Use appropriate shielding gas: Protect the welding area with pure argon (Ar) to prevent oxidation and contamination. Proper welding sequence and speed: Ensure uniform welds and avoid uneven heat effects that may cause cracking.
