Non-copper coated welding wires AWS ER70S-6
Standard: GB/T ER50-6 / AWS ER70S-6
⚙️ APPLICATION
Non-copper coated wire is used for welding 500MPa low alloy steel single and multi-pass welding; also for high speed thin plates, pipe line steel welding. Suitable for manual welding, automatic welding and robot welding, such as oil machinery, heavy crane machinery, pressure vessels, oil-chemical vessels, ship body, construction steel structure, etc.
✨ CHARACTERISTICS
CO2 gas-shielded copper-plated welding wire has excellent welding technological property: the electric arc is stable with less spattering, the appearance of welded joint is nice with good crack resistance: it applies to all-position welding.

Frequently Asked Questions (FAQ)
1. What is the main advantage of non-copper coated welding wire?
Non-copper coated wires reduce copper fume emissions during welding and eliminate the issue of copper coating flaking, which can clog liners and contact tips, leading to more stable arc performance.
2. Which materials can be welded with AWS ER70S-6?
It is primarily used for welding 500MPa grade low alloy steels, thin plates at high speeds, and pipeline steels. It is also ideal for pressure vessels and structural steel works.
3. Is this welding wire suitable for robotic welding?
Yes, it is highly suitable for manual, automatic, and robotic welding due to its stable electric arc and low spatter characteristics.
4. What are the available packaging options for this wire?
We offer various options including D100, D200, and D300 plastic spools, K300 metal spools (ranging from 1kg to 20kg), and large 250kg/350kg drum packing.
5. What is the typical lead time for an order?
Standard delivery is within 15-20 days following the confirmation of the down payment.
6. Does the wire support all-position welding?
Yes, the CO2 gas-shielded wire is designed for all-position welding, providing excellent crack resistance and a smooth welded joint appearance.
