Introduction

For thick aluminum plate welding (e.g., over 10mm), large diameter wire is used to maximize the deposition rate, reduce the number of weld passes, and lower overall labor costs. Our large diameter wires (typically 1.6mm, 2.0mm, 2.4mm) are manufactured for exceptional stiffness and straightness, ensuring reliable feeding through heavy-duty welding equipment. This material is primarily used in structural, shipbuilding, and pressure vessel fabrication where high integrity and productivity are equally critical.

Specification

Diameter Range1.6mm, 2.0mm, 2.4mm, and up to 3.2mm
Key PropertyHigh deposition rate, Deep penetration capability
Process FocusHigh-amperage MIG (GMAW), Submerged Arc Welding (SAW - rare)
Supply FormLarge spool (18kg/25kg) and bulk drums (50kg+)
ToleranceControlled stiffness and cast/helix for reliable feed

Applications

  • Heavy structural welding in shipbuilding (hulls, decks, large bulkheads).

  • Fabrication of large pressure vessels, cryogenic tanks, and storage silos.

  • Welding thick aluminum plates for bridge structures and heavy transportation frames.

  • High-amperage, high-deposition automated or mechanized welding.

FAQ

  • Q: Is large diameter aluminum wire compatible with standard MIG welding torches?
  • A: It requires heavy-duty, high-amperage torches, feeders, and gun liners designed to handle the increased stiffness and current load of the large-gauge wire. Standard equipment may fail or cause severe feeding issues.
  • Q: What are the main challenges when welding with very large diameter aluminum wire?
  • A: Challenges include maintaining a manageable weld pool (requiring high skill and travel speed), ensuring proper fusion at the root of the joint, and managing the extremely high heat input to control distortion.

Advantages

  • Maximized Deposition: Significantly increases the amount of weld metal deposited per hour, dramatically reducing fabrication time and costs.

  • Reduced Passes: Allows for single-pass or fewer-pass welds on thick material, reducing heat input and minimizing distortion.

  • Robust Feeding: The inherent stiffness of the larger diameter wire ensures smooth and consistent feeding, even in longer conduits and under high-speed conditions.

  • High Integrity: Provides the deep penetration necessary to achieve full fusion on heavy-section joints.

Payment and Shipping

  • Logistics: Optimized bulk packaging solutions to handle the high density and weight of large diameter wire shipments.

  • Technical Support: Consulting on parameter settings (voltage, wire feed speed) to maximize deposition and penetration with these specialized gauges.

  • Pricing: Volume-based discounts available for bulk purchases of large diameter consumables.
