Hyundai S-7016.H Low Hydrogen Electrodes – 3.2mm: Premium Welding Solution for High Tensile Steel
The Hyundai S-7016.H Low Hydrogen Electrode (3.2mm) is engineered for high-performance welding in demanding applications, such as bridges, buildings, shipbuilding, high-pressure vessels, and rolling stock. This low hydrogen electrode ensures exceptional weld quality with superior crack resistance and X-ray performance, making it the ideal choice for high tensile steel welding.
Key Features:
- Soft Stable Arc: The S-7016.H electrode ensures a smooth, consistent arc, reducing spatter and improving weld appearance.
- Smooth Appearance: Results in clean, aesthetically pleasing welds with minimal post-weld cleaning.
- No Undercut Formation: Prevents undercutting, offering a stronger and more reliable joint.
- Excellent Slag Removability: The slag has good fluidity, making it easy to remove, ensuring a clean finish.
- Superior Mechanical Properties: With high tensile strength and excellent elongation, this electrode guarantees solid performance under stress.
- Crack Resistance & X-ray Performance: Designed for optimal crack resistance, it excels in critical applications requiring X-ray inspection.
Usage Guidelines:
- Preheat: Dry electrodes at 300–350°C (572–662°F) for 60 minutes before use to maintain low hydrogen content and avoid cracking.
- Arc Starting: Use the back step method or strike the arc on a small steel plate to prevent blowholes during arc initiation.
- Wind Protection: Ensure a windscreen is used in windy conditions to prevent arc instability and ensure quality welds.
Welding Positions:
- F, HV, VU, OH: Suitable for a range of positions including flat, horizontal vertical, vertical up, and overhead welding.
Current Type:
- AC or DC±: Compatible with both AC and DC welding machines for versatile operation.
