Article Preview

The contribution is dealing with suggestion of tool geometry affecting weldability of Mg alloy AZ31B at friction stir welding. Four welding tool made of tool steel H13 (X40CrMoV5-1) with different geometry have been used at welding. Weld joints with high quality have been performed at following parameters: tool revolutions 600 rpm, welding speed 40 to 120 mm/min, angle of inclination 3° and pressure force 38 kN. Area of weld metal accounted fine-grained structure with average dimension of grain 13 μm. Structure is formed by solid solution α - Mg, Al-Mn particles and compound MgAl3Mn2. Strength of weld joint reaches value 265 MPa. Fracture areas accounted character of ductile fracture.
