Best for stainless steel components in assemblies requiring durable, crack-resistant joints. Caution: ensure compatible shielding gas and cleaning before welding to protect corrosion properties.
YESWELDER ER70S-6 Mild Steel TIG Rod
YESWELDER ER70S-6 is a gas-shielded copper-coated carbon steel TIG rod suitable for mild steel fabrication. It uses high manganese and silicon deoxidizers for smoother beads with minimal post-weld cleanup. Best for general TIG welding tasks on mild steel. Limitation: shield gas and current settings significantly influence bead quality and spatter.
Buying Guide: Key Purchase Considerations
- Material compatibility: Match rod type to the base metal (steel, stainless, aluminum, or cast). For hard facing, select rods designed for wear resistance and abrasion, such as RC 58-60 hardfacing offerings.
- Hardness needs: If you require higher surface hardness, prioritize products labeled with hardness ranges in the mid-to-upper RC range and verify compatibility with your welding process.
- Welding position and equipment: Some rods are better in all-position use; others perform best with specific current or shielding gas settings. Choose accordingly.
- Application type: For overlays and wear parts, consider multi-pass capability and the likelihood of cracking resistance or corrosion resistance depending on exposure.
- Ease of use: For less-experienced operators, select electrodes known for easier application and stable arc, with clear guidance on current and pass sequence.
- Shielding gas requirements: TIG rods often require 100% argon or argon blends; ensure your equipment supports the gas used by the rod.
- Caution about data gaps: Manufacturer notes can vary; rely on the stated hardness, application notes, and pass recommendations rather than general assumptions.
FAQ
- What is hard facing TIG rod used for?
– Used to apply wear-resistant overlays on parts that experience abrasion or impact, extending service life. - Which rod is best for high-abrasion wear?
– Rods with higher RC hardness (such as RC 58-60) are typically better for heavy abrasion applications.
- Do I need shielding gas for TIG hard facing?
– Yes, most TIG rods require shielding gas, commonly 100% argon, to protect the weld and ensure good bead quality. - Can I use mild steel TIG rods for hard facing?
– Mild steel TIG rods are not ideal for hard facing overlays intended for abrasion resistance; use dedicated hardfacing rods for overlays. - Are stainless TIG rods suitable for hard facing?
– Stainless rods are best for corrosion-resistant welds; use dedicated hardfacing alloys for wear overlays when appropriate.
