Because of their high temporary tensile strength and significant fatigue strength, DOCOL steels from the AHSS group (AHSS – Advanced High-Strength Steel) are often used in the fabrication of mobile platforms. The welding of the above-named steels is difficult due to the dominant martensitic structure and requires extensive experience. The article discusses the identification and adjustment of welding parameters appropriate for steel DOCOL 1300M and presents the assessment of the effect of selected process parameters, i.e. filler metal wires, shielding gas mixture and, primarily, the correct preheating temperature, on the quality of welded joints.
