Description
GeKa – Si ALUWELD (4043) Electrodes (4.0mm) 2kg
The GeKa Si ALUWELD (4043) Electrodes are designed for manual welding applications on forged and cast aluminium alloys. These electrodes are particularly useful for repairing cracks, casting defects, building up sections, and mending broken parts. For optimal results on thick sections, a preheat at 200°C is recommended.
Features & Benefits:
- Suitable for welding both forged and cast aluminium alloys.
- Ideal for various repair works including cracks, casting defects, and building up sections of broken parts.
- Preheating at 200°C is recommended when welding thick sections.
- Packaged in hermetically sealed tin cans to ensure product quality.
- Complies with recognized industry standards: TS 9604-EL-AlSi 5 and AWS A5.3-E4043.
- Offers a yield strength ranging from 160-190 N/mm2 and a hardness of 50 HB.
Common Applications:
- Engine blocks, gear cases, engine gearbox units, and miscellaneous components made of light alloys.
- Storage tanks, containers, and vessels.
- Repair works on various aluminium materials.
