Problems of reparatory welding of the broken mandrel axle-shaft are thought of on this paper. After visual inspecting of the damaged half and analysis of the crack position and static and dynamic loads, which brought on the fracture, it was estimated that the damaged part could possibly be repaired, however by a really complicated welding procedure mixed with heat remedy. The axle-shaft was successfully repaired and the spinner was capable of operating. The downtime was significantly decreased and the costs of procuring/manufacturing the brand new part prevented.

• The peak temperatures reached inside the softest HAZ had been between Ac1 and Ac3 (730–870 °C on this case).
• The hardness of the bottom materials ranged between 224 and 264 HV, whereas the hardness of the softest zone of the heat affected zone was roughly one hundred fifty HV , emphasizing an enormous mismatch when evaluating BM hardness to the minimum HAZ hardness.

The temperature cycles had been measured and then the obtained values for the important cooling time t8/5 have been entered into the CCT diagrams to estimate the hardness and microstructure of the welded joint’s zones. Experiments had been conducted on the multi-layered hard-confronted samples made from the steel for manufacturing of the forging dies. The examine evaluates numerically and experimentally the effect of welding heat enter parameters on the microstructure and hardness of the warmth-affected zone of quenched and tempered and thermo-mechanically controlled course of 690-MPa high-energy steel. Numerical analyses and experimental comparisons have been applied using three warmth input values (10, 14, and 17 kJ/cm) so as to predict the thermal fields throughout welding. Experimental analysis was carried out of the microstructure and microhardness behavior in different HAZ areas.

In the circumstances of the overmatched welded joints containing a soft root layer it’s attainable to attain a comparable fracture behaviour related to the homogeneous overmatched welded joint if the impact toughness of the delicate root layer is greater than the impression toughness of the overmatched weld steel. Such a type of welded joint is due to this fact preferable for the welding of excessive strength low alloy steels, because it allows the manufacturing of a welded joint without preheating. High energy steels belong into a group of top of the range steels, with exceptional mechanical properties, especially in regards to tensile power. At the identical time, as their deficiency is emphasized the restricted and difficult weldability. In different words, a few of these steels are weldable solely with application of particular measures associated to controlled heat input.

The numerical values indicate that the maximum respective values of temperature measured in QT steel and TMCP metal have been about 1300 and 1200 °C for a heat enter of 10 kJ/cm, 1400 and 1300 °C for a warmth input of 14 kJ/cm, and 1600 and 1450 °C for a warmth input of 17 kJ/cm. The cooling times resulted, for a heat input of 10 kJ/cm, in numerical t8/5 (14.5 s) and experimental (18.84 s) increases in hardness within the coarse-grain warmth-affected zone of the QT steel (317 HV0.1), due to the formation of bainite and lath martensite buildings with grain growth. Decreased hardness in the CGHAZ of TMCP steel (240 HV0.1) was brought on by primary recrystallization of the microstructure and the formation of more equilibrium products of austenite decomposition. Increasing the heat enter (14 to 17 kJ/cm) led to numerical t8/5 and experimental decreases in hardness within the CGHAZ of QT steel (270 HV0.1) due to the full austenite , and maintained the relative value of TMCP steel (235 HV0.1). This paper presents analysis of the influence toughness and hardness distribution in particular zones of a ‘single V’butt multiple-pass welded joints of the high-power low-alloyed steels. Obtained values of the influence toughness are analyzed in correlation with a microstructure in particular zones of the welded joint, together with the micro hardness distribution discovered in the related zones. Based on the carried out analysis and results obtained in experiments, the applied expertise of welding was evaluated.
