This detailed product description applies to the high-quality AlMg3 welding wire made of aluminium-magnesium alloy, designed for professional applications, especially in the fields of automotive repair and general metal fabrication tasks. The product is an ideal choice for both MIG (Gas Shielded Metal Arc Welding) and TIG (Tungsten Inert Gas Welding) procedures.
This welding wire is available in the Wieländer+Schill assortment with the following identifier:
Part number: 311083
Wire material: AlMg3 (Aluminium-Magnesium Alloy)
Wire diameter: 1.2 mm
Packaging quantity: D200 type plastic spool
Net weight: 2 kg
The AlMg3 welding wire is a consumable electrode made from a specially formulated aluminium-magnesium alloy, which is excellently suited for welding seams of the same or similar aluminium alloys. The 1.2 mm diameter provides an optimal balance between high throughput capacity and precise arc control, especially when working with thinner sheets and medium-thickness materials.
The wire is wound onto a D200 plastic spool, ensuring easy handling and smooth, unobstructed feeding of the wire into the welding equipment. The 2 kg packaging is ideal for frequent, but not extremely high-volume use, ensuring fresh material availability.
This welding wire is primarily intended for welding aluminium alloys, particularly in cases where the weld seam must ensure high strength and good corrosion resistance.
Important procedural notes:
Welding processes: Suitable for TIG (Argon I1 shielding gas) and MIG (Argon I1 or Argon-Helium I3 mixtures) welding.
Heat Treatment (Preheating): For large workpieces and wall thicknesses exceeding 15 mm, preheating the surface to be welded to 150 °C is recommended to minimize residual stress and the risk of cracking.
The correct selection of shielding gas is critical to achieving a high-quality weld seam.
| Welding Procedure | Recommended Shielding Gas (EN ISO 14175) |
|---|---|
| TIG Welding | Argon (I1) |
| MIG Welding | Argon (I1) or Argon-Helium mixtures (I3) |
The mechanical properties of the wire guarantee the reliability and durability of the weld seam.
| Property | Value | Unit of Measure |
|---|---|---|
| Wire diameter | 1,2 | mm |
| Weight | 2 | kg |
| Length × Width × Height (Spool dimensions) | 200 x 200 x 54 | mm |
| Tensile strength ($R_m$) | 200 | N/mm² |
| Yield strength ($R_{p0.2}$) | 80 | N/mm² |
| Elongation | 20 | % |
| Winding Type | D200 Plastic Spool | – |
Tensile Strength (200 N/mm²): This value indicates the maximum load capacity of the welded joint before the material tears. In the case of AlMg3, this strength is sufficient for most structural applications.
Yield Strength (80 N/mm²): Defines the stress under which the material undergoes permanent deformation. This data is important for designing statically loaded welds.
Elongation (20%): The relatively high elongation value indicates that the weld seam is flexible, capable of absorbing stresses resulting from external loads without brittle fracture.
For an undisturbed welding process, special accessories are recommended for the D200 spools:
Centering adapter for D200 wire spool
Part number: 307004
Function: This centering adapter set ensures the precise and straight positioning of the D200 wire spools on the spool arbor. This is essential for the wire to arrive straight and without distortion at the wire feeder inlet, thereby preventing feeding problems and arc instability.
The Wieländer+Schill AlMg3 1.2 mm welding wire is a reliable, industrial-grade consumable with excellent mechanical properties. The carefully selected alloy and precise manufacturing process guarantee consistent welding results with both TIG and MIG procedures, making it an ideal choice for professional bodywork and light industrial applications. The D200 packaging offers a practical solution for efficient material usage.
