A top-choice electrode for welding on thick sections and restrained joints when cracking is an issue. It's also a good call when the project involves hard-to-weld steels. Jetweld® LH-70 also offers high deposition rates
- Medium penetration
- Smooth arc performance
- Capable of x-ray quality and excellent notch toughness
- Low hydrogen may reduce the need for preheat or postheat
- Shipped in hermetically sealed containers, which can be stored indefinitely in normal conditions, without danger of moisture pickup
- Tolerates high sulfur and high silicon steels which have poor weldability
- Flat, horizontal, vertical up, overhead welding positions
- 1 - 2mL/100 g weld metal diffusible hydrogen
