I. APPLICATIONS:

Fabrication, construction and repair maintenance work, structural steels, machinery and construction equipment, truck bodies, auto parts, farm implements, storage tanks, ornamental iron works, metal furniture, bicycles, sheet metals, etc. For all position welding, weld with CO2 gas or DC reverse polarity. Designed for welding of unalloyed steels, e.g. general structural steels and pressure vessel steels with a minimum, tensile strength of max. 530 N/mm2 as well as for fine-grained carbon-manganese steels for the same purpose with a yield strength of min. 420 N/mm2.

II DESCIRPTION:

For welding of mild steel and 490  N/mm2 H.T. steel and aluminum killed steel for low temperature use.

 TEST RESULT

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. Typical data and Test results for mechanical properties, deposit or electrode composition and other properties 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.
