Jetweld LH-70

Jetweld® LH-70 is a semi iron powder electrode that gives highest deposition rates consistent with good out of position welding capability . Goodcharpy and CTOD values.

Where x-ray quality and excellent mechanical properties arerequired.

Thick sections and restrained joints in mild and low alloy steelswhere shrinkage stresses tend to cause weld cracking.

To reduce pre-heat requirements.

To resist cracking in medium to high carbon and hard to weld steels.

To resist hot shortness in sulphur and phosphorus bearing steels.

To reduce porosity in sulphur bearing steels

Vertical and overhead welding.

The product comes standard in a hermetically sealed can whichallows for immediate use from the can and for up to 9 hours beforere-baking is required.

T E S T R E S U L T STest results for mechanical properties, deposit or electrode composition and diffusible hydrogen levels were obtained from a weld produced and tested according to prescribed standards,and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitabilityof any welding consumable and procedure before use in the intended application.
