Castolin EnDOtec DO*257
Remarkable crack resistant weld metal in combination with very low (<3ml/100gr) hydrogen content. Therefore, suitable for the economic processing of high-strength up to 690 MPa and low temperature fine grained structural steels. Excellent welding properties in short and spray arc. High deposition rate and no intermediate cleaning required with very low spatter loss. Excellent wetting properties compare to solid wires that results in a bigger parameter range and improved duty cycle for the welder.
