Aluminium Welding Wire
MIG / TIG Aluminium Welding Wire
Overview
Precision-drawn aluminium welding wires for MIG and TIG applications — consistent chemistry and tight diameter tolerances ensure smooth arc transfer, low spatter and high-quality weld deposits
Store in dry conditions; use within recommended shelf life to prevent oxide pick-up

Properties
Manufacturing Process
Step 1
Alloy Preparation
High-purity aluminium ingots and alloying additions (Si, Mg) are batched to tight composition targets required by AWS A5.10 / EN ISO 18273.
Step 2
Continuous Casting
Molten alloy continuously cast into rod; rapid solidification ensures a fine grain structure ideal for subsequent cold drawing.
Step 3
Multi-pass Wire Drawing
Rod progressively drawn through tungsten-carbide dies to final wire diameter (0.8–3.2 mm) in multiple cold-drawing passes with intermediate anneals.
Step 4
Surface Cleaning
Wire surfaces cleaned and lubricated with weld-compatible drawing oil; bright, oxide-free finish verified before spooling.
Step 5
Spooling
Wire precision-wound onto plastic or steel spools in standard weights (0.5–15 kg) with controlled traverse for tangle-free payoff during welding.
Step 6
QC & Certification
Chemistry verified by OES; tensile, elongation, and diameter checked per lot; AWS / ISO compliance certificates issued with every shipment.
