Premium Solid Welding Wire for Laser Welding & MIG/MAG Systems
Engineered for high-precision industrial applications, our solid welding wires deliver stable automatic wire feeding, superior deoxidation performance, and smooth weld bead formation. Perfect for handheld laser welding machines, MIG/MAG welding, and continuous production lines. Available in various grade options for carbon steel, aluminum alloys, and stainless steel substrates.
Key Features & Quality Advantages
Smooth & Stable Feeding
Precision-drawn wire surface minimizes feeding resistance, preventing burn-backs and wire jams in laser feeding conduits.
Strong Deoxidation Performance
Formulated with balanced deoxidizers to effectively prevent porosity and crack formation, ensuring high tensile strength welds.
Dual Process Compatibility
Optimized specifically for handheld laser welding machines while remaining fully compatible with conventional MIG/MAG systems.
Clean Weld Appearance
Produces minimal spatter, stable arc characteristics, and aesthetic, uniform weld seams requiring little to no post-weld grinding.
Wire Grade & Material Selection Guide
| Wire Model | Material Classification | Recommended Applications |
|---|---|---|
| ER70S-6 | Carbon Steel Solid Wire | Mild steel, structural carbon steel welding with excellent arc stability. |
| ER5356 | Aluminum-Magnesium Alloy Wire | 5000-series aluminum alloys, structural aluminum parts requiring high shear strength. |
| ER4043 | Aluminum-Silicon Alloy Wire | 6000-series aluminum alloys, cast aluminum, offering great crack resistance and fluidity. |
| Stainless & Copper Wire | Special Alloy Solid Wires | Stainless steel alloys, copper, and dissimilar metal joining applications. |
Selection Notice: Please double-check your machine's wire feeding wheel roll type, wire liner material, and wire diameter (e.g., 0.8mm / 1.0mm / 1.2mm / 1.6mm) before placing your order.

Frequently Asked Questions
What is the difference between ER4043 and ER5356 aluminum wire?
ER4043 contains silicon, providing better puddle fluidity, lower melting temperature, and reduced crack sensitivity (ideal for 6000-series aluminum). ER5356 contains magnesium, offering higher tensile strength and better color match after anodizing (ideal for 5000-series aluminum).
Which feeding tube liner should I use for aluminum welding wire?
For aluminum welding wire (ER4043 / ER5356), we strongly recommend using a graphite liner rather than a steel spring liner to avoid wire shaving, friction, and jamming.
Is this solid wire suitable for auto wire feeders on laser welders?
Yes. The smooth surface finish and precise diameter tolerances ensure stable and continuous feeding through standard wire feeding systems used with handheld laser welding heads.
