There's a long list of reasons why operators are so loyal to Excalibur 7018 MR. They tell us they love the clean puddle, the square coating burnoff, the easy all-position handling and the excellent wash-in characteristics. Its a terrific choice for jobs that involve steels with poor weldability.

Advantage Lincoln

- Designed for welding mild steel, low alloy steels and steels of poor weldability.
- Capable of x-ray quality welds.
- Ability to tie-in to side walls without undercutting, especially for critical out-of-position applications.
- Clean weld puddle and uniform slag follow make it easy for the welder to see and carry the puddle.
- Manufactured under a quality system certified to ISO 9001 requirements.
 
Typical Application
 
- Structural steel and bridges.
- All-position welding of mild steels, and some high strength, low alloy steels.
- Tolerates steels with poor weldability, such as high sulfur and high silicon steels.
- Welding of piping, fittings, and tie-ins in the petrochemical and power generation industries.
