Description

Geka GrabPak 4043 Aluminium TIG Wire (1.6mm) 0.5kg – AlSi

AWS A5.10 92 ER4043 EN 18273-S 2004 AL4043

A 0.5kg GrabPak of Geka® 4043 AlSi Aluminium TIG rods (1.6mm). Super handy, the grab packs are great for hobbyists needing smaller quantities of rods or for small maintenance jobs when TIG welding aluminium.  Perfect also for site work, these grab packs are supplied in a plastic re-useable tube to keep them dry and undamaged.

Regarded as the most popular grade of all Aluminium TIG Welding Rods. This welding wire is an excellent choice of aluminium 5% Silicon filler rods for ornamental applications where design results are critical. Consequently, the addition of 5% Silicon creates a more fluid weld pool. Aluminium filler rods require pure argon as a shielding gas. It is important to remember 4043 TIG welding rods are not suitable for anodising.

Working with thicker metals may require a mix of Helium and Argon, due to it being a hotter shielding gas that will give better penetration. Furthermore, use 4043 Aluminium TIG Welding Wire when repairing or making housings and crankcases. Manufacturing cylinder heads and blocks, creating ornamental aluminium pieces are also good uses for these filler rods. Plus fabrication of boats, trucks and bus bodies, along with making vats, tanks or containers.

Provides excellent corrosion resistance for applications where this is a key factor. Packaged in plastic storage containers which give great protection from dirt and debris.

An aluminium alloy with 5% silicon, with excellent flow characteristics and penetration. Suitable for welding duralumin cast (LM25) and wrought alloys 6063 (H9), 6061 (H20) and 6082 (H30). Weld will discolour if anodised. Can be used TIG or in Oxy Acetylene. If used in Oxy Acetylene, use Aluminium brazing and welding flux.

Features & Benefits
  • Most popular grade of aluminium TIG welding rods.
  • Excellent corrosion resistance.
  • 5% Silicon creates good levels of fluidity in the weld puddle.
  • Pre heat is generally not required, except when welding heavy sections
  • 4043 is not sensitive to weld cracking
Industries / Applications
  • Automotive Sector
  • Production of mobile equipment
  • Shipbuilding
  • General repair and maintenance
What is weld cracking?

Weld cracking can have very significant consequences particularly as it increases high-stress intensity.  As a result, this can cause unexpected weld failure.  Weld cracking is broken down into two categories as detailed below:

  • Hot Cracks – Formed during the cooling process immediately after welding.
  • Cold Cracks – When there has been a delay between the crack forming and the weld being finished.

Weld cracking can occur during the weld process itself which is likely to be caused by fatigue or corrosion. Treatment of a weld crack will vary depending on how and at what stage the crack has formed.  This must be established first before any corrective action is taken.

In Conclusion

As shown above Geka™ Grabpak 4043 Aluminium TIG rods are ideal for hobbyists and small maintenance jobs.  The 5% silicon content ensures good weld puddle fluidity.  Additionally welds are less sensitive to weld cracking, producing bright almost smut-free welds. Used for applications including general repair and maintenance within industries such as automotive, shipbuilding and the production of mobile equipment. Finally it is important to remember these TIG rods are not suitable for anodising welds will discolour.
