Description:
The Böhler FOX DMO Kb is a stick electrode with a basic coating. The weld metal of this electrode, corresponding to the 0.5Mo type, exhibits a microstructure of acicular ferrite and bainite. Thanks to its favorable mechanical properties, it is well-suited for use both in the as-welded condition and after heat treatment. This electrode finds application in a wide range of welding tasks, from joining similar creep-resistant steels and cast steel to joining high-strength structural, fine-grain, and pipeline steels. The Böhler FOX DMO Kb is approved for long-term use at temperatures up to 550 °C and shows excellent notch toughness at temperatures below -50 °C.
The coating type, specifically tailored to the electrode's core, exhibits low moisture absorption, ensuring a low content of diffusible hydrogen in the weld metal. Furthermore, the electrode achieves a weld metal recovery of 115%.

Special notes
The settings for preheating, interpass temperature, and post-weld heat treatment should be adjusted according to the requirements of the base material. As a general recommendation, preheating in the range of 100 to 250ºC can be used depending on the material thickness. Typical temperatures for post-weld heat treatment range from 520-620ºC.
