“…A tensile residual stress increases the mean stress, which will, in turn, increase the maximum stress level reached during service. In cyclic loading conditions, each cycle will cause an increase in fatigue damage through crack growth [65,66]. This will continue until the critical crack length results, leading then to crack propagation and component failure.…”

Fatigue fracture is one of the major degradation mechanisms in the low-alloy 4330 carbon steel pumps that are utilized in the hydraulic fracturing process operating under cyclic loading conditions. A weld cladding technology has been developed to improve the ability of these components to resist fatigue crack initiation by cladding them with a secondary material. This process introduces a residual stress profile into the component that can be potentially detrimental for fatigue performance. The cladding technology under examination is a low-alloy 4330 carbon steel substrate weld that is clad with the nickel-chromium-based superalloy IN625 and is investigated herein using several experimental residual stress measurement techniques. Understanding the magnitude and distribution of residual stress in weld clad components is of the utmost importance to accurately assess the performance of the component in service. This study summarizes the results of residual stress measurements that were determined using X-ray diffraction, i.e., hole drilling based on electronic speckle pattern interferometry, deep-hole drilling, and the contour method, to obtain the residual stress distributions from the surface of the weld clad, through the clad layer, and into the substrate material. The results of deep-hole drilling and the contour method show large-scale tensile residual stress in the clad layer and compressive residual stress in the majority of the substrate. However, the X-ray diffraction and hole drilling methods indicate the presence of short-scale compressive residual stress on the surface and near the surface of the clad layer. It was shown that these Manuscript

“…The impact of porosity can cause cracks in the weld, decreased conductivity, and fatigue failure [12], [13]. Fatigue properties are also influenced by residual stresses in welded joints [14], [15]. One way to reduce residual stress is post-weld heat treatment (PWHT) [16].…”

“…The vibration method is able to release residual stresses without changing the shape and microstructure [36]. The vibration method is able to reduce residual stresses and is effective for homogenization of concentrated residual stress [14], [15]. Therefore, this article review provides an understanding of how to increase fatigue resistance by reducing porosity and residual stress with the vibration method, so that it will help and facilitate further research.…”

Fatigue resistance is influenced by porosity and residual stress in welded joints. Fatigue failure in some means of transportation is caused by the inability to withstand the load received from the car body and passengers while operating. This study uses a systematic literature review (SLR) method to identify the effect of vibration welding on porosity and residual stress. Vibration can reduce the empty cavity (porosity) and increase the density of the weld. The ultrasonic vibration spot resistance (UVSR) method with 20 kHz on AA6082 is able to reduce residual stress up to 53% and is effective for homogenization of concentrated residual stress up to 57%.

“…3,4 Under this condition, the fatigue lives of workpieces could be shortened [5][6][7] by means of increasing the fatigue crack growth rate. 8,9 So how to relieve the local larger tensile residual stresses in the workpieces induced by the machining and manufacturing process, e.g., the high-energy pulsed-laser technology and the welding process, has become an important topic in the industrial community.…”

The high-energy oscillating electric current pulse (ECP) technology was introduced to relieve the residual stresses in the small AISI 1045 steel specimens treated by the pulsed-laser surface irradiation. The high-energy oscillating ECP stress relief experiments were conducted to study the effectiveness of the high-energy oscillating ECP technology. In addition, the electroplasticity framework was developed based on the thermal activation theory to reveal the mechanism of the high-energy oscillating ECP stress relief. The results show that the high-energy oscillating ECP stress relief has good effects on eliminating the residual stress. Furthermore, the residual stress relieving mechanism of the high-energy oscillating ECP stress relief can be attributed to the electric softening effect and the dynamic stress effect. The findings confirm that the significant effects of high-energy oscillating ECP on metal plasticity and provide a basis to understand the underlying mechanism of the high-energy oscillating ECP stress relief.
