T E ST R E S ULTS
Test 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 suitability of any welding consumable and procedure before use in the intended application.
