- 摘要：By optimizing the welding parameters of nonpenetration laser lap welding of stainless steel with two plate thickness combinations（2 mm +1.5 mm, 1.5 mm +2 mm）, the laser welding quality control under the condition of multi-parameter coupling was realized, and their fatigue performances were studied. The welding process test is designed by orthogonal test method. According to the orthogonal test results, the relationship between three key welding parameters（power,welding speed, defocusing amount） and shear strength of welded joints of these two plate thicknesses combinations is ana lyzed. And the optimal welding parameters are obtained, namely1.5 mm+2 mm plate thickness combination（power of 3 700 W,welding speed of 4 330 mm/min, defocusing amount of +4 mm）and 2 mm+1.5 mm plate thickness combination（power of 3 700 W, welding speed of 4 580 mm/min, defocusing amount of0 mm）. The fatigue properties of laser welded joints of these two plate thickness combinations under the optimal welding parameters are comparatively analyzed. The fatigue strength of welded joint of 2 mm+1.5 mm composite is higher than that of1.5 mm +2 mm composite, which provides a reference for further parameters optimization r and fatigue properties study of laser welding of stainless steel carbody.关键词：laser lap welding;orthogonal design;variance analysis;welding parameter optimization;fatigue limit

On the basis of flat welding, the weld characteristics were analyzed under the conditions of different laser powers, defocusing amounts, welding speeds and side blow pressures. The welding parameters were optimized and the weld forming was controlled by self-made small side blow device.The results show that when the laser power reaches 30 k W, it is difficult to obtain a good weld formation only by changing the defocusing amount or welding speed, and the weld uniformity is poor and the welding spatter is large. Applying transverse side blow pressure of 0.3 ～0.4 MPa on the test plate can effectively improve the weld formation, reduce the welding spatter, and increase the weld penetration depth by more than 20%. Through the further optimization of the welding parameters, the weld surface forming control was realized during 30 kW laser welding with transverse side blow pressure of 0.4 MPa and welding speed of 0.6 m/min.关键词：10 kW level;fiber laser;30 kW;parameter optimization;side blow

发布时间：2022-03-14 - 摘要：Flow passage components often fail due to surface wear in service. The traditional wear-resistant treatment method has limited effect on improving the service life of flow passage components, and there are some problems such as expensive equipment, complex process or high cost of raw materials. Researchers observed prepared Ni Cr BSi, Ni Cr BSi/WC,Ni Cr BSi/diamond wear-resistant braze coating, and found that the metallurgical bonding between the coating and the matrix was good. In Ni Cr BSi coating, chromium carbide, chromium boride, nickel boride and other strengthening phases are formed. In Ni Cr BSi/WC coating, the distribution density of WC particles gradually increases from the coating surface to the bottom, while in Ni Cr BSi/diamond coating, diamond particles are uniformly dispersed. Under the same wear test conditions,the mass loss of Ni Cr BSi/diamond coating is about 1/5 that of Ni Cr BSi coating and 1/3 that of Ni Cr BSi/WC coating, indicating that Ni Cr BSi/diamond coating has excellent wear resistance. The diamond brazecoating technology has been applied to rotating blades of soil-engaging components and screw conveyor blade of agricultural machinery touching the soil. The field test shows that the wear resistance and service life of the rotary tiller and screw blade coated with diamond brazing have been greatly improved. It provides theoretical reference and practical experience for the application of diamond brazing technology in other flow parts in the future.关键词：brazecoating;diamond coating;wear failure;wear-resistant coating;flow passage components

Through arc additive manufacturing and repair with welding wire ER4043, the lacking part was repaired perfectly. The means of nondestructive testing, microhardness tester, electronic universal testing machine and scanning electron microscopy were used to study and analyze the microstructure and performance of the repaired part in arc additive manufacturing and repair. The results show that the surface of repaired sample has no surface-breaking defect, and the internal microstructure is dense without visible defects. The microhardness at the top of repaired sample is a bit higher than that at the bottom, and the microhardness in the middle part is stable. The mechanical properties of the sample parallel to the direction of arc cladding are superior to those perpendicular to the direction of arc cladding. Therefore, the mechanical properties of repaired sample are anisotropy. The Al-Si eutectic structure of repaired sample showing fine strips distributes in α solid solution, and extends from bottom to top. The Al-Si eutectic structure at the top of repaired sample disperses and has small cutting effect onα matrix, which makes the properties of Al-Si eutectic at the top better than those at the bottom.关键词：aluminum alloy;arc additive manufacturing;repair;reverse modeling

The relationship between the process parameters such as laser power, welding speed, and defocused position of the laser beam with the output responses such as top melt width, back melt width, back-to-top width ratio and fusion zone area are established in terms of 3 D response surface models. The models are significant and fit well. The influence of process parameter on the geometric characteristics of welded joints and the microstructure properties of typical welds are analyzed. The results show that the laser power is positively correlated with back melt width, back-to-top width ratio and fusion zone area; welding speed is negatively correlated with all output variables; the defocused position is positively correlated with top melt width and fusion zone area, while negatively correlated with back-to-top width ratio. There is an obvious interaction between laser power and defocused position in the regression model of back-to-top width ratio. The single-mode fiber laser can realize the full penetration of 2 mm 6013 aluminum alloy under the process matching of low power and high welding speed, and the section melting width of the welded joint is narrower and the micro grain size is small.

The results show that Tri-Arc dual wire welding not only has the same welding efficiency as Tandem dual wire welding, but also has a lower welding heat input than Tandem dual wire welding under the same wire deposition rate（wire feed speed） and welding speed conditions. The results are reflected in lower weld penetration ratio and less welding deformation. Therefore, Tri-Arc can replace Tandem in all efficient welding applications and achieve the same or even higher wire deposition rate, as well as providing superior welding performance and a wider range of applications.关键词：Tri-Arc dual wire arc welding;Tandem dual wire arc welding;deposition rate;heat input

发布时间：2022-03-14 - 摘要：The solidification processes of twin-roll strip casting Cu-3.2 Ni-0.75 Si alloy at different cooling rates were observed in situ by confocal laser scanning microscope（CLSM）,and the functional relationship between the crystallization temperature and the secondary dendrite spacing of the solidified structure depending on cooling rate was quantitatively analyzed.The results show that the increase of cooling rate can significantly reduce the crystallization temperature and the secondary dendrite spacing of the solidified structure. When the cooling rate increases from 0.1 ℃/s to 100 ℃/s, the crystallization temperature decreases from 1 096 ℃ to 890 ℃,and the secondary dendrite spacing increases from 77.5 μm to23.5 μm, the function relations of crystallization temperature and secondary dendrite spacing depending on cooling rate are TL→ S=194×（-v/14）+895 and λ2=60×v-0.11, respectively. The subrapid solidification characteristics of twin roll strip casting can significantly refine the solidification structure of the alloy and inhibit the microsegregation of Ni and Si elements. The reason is that the increase of cooling rate enhances the initial undercooling of the alloy melt during crystallization.关键词：in-situ observation;twin-roll strip casting;Cu-Ni-Si alloy;secondary dendrite spacing;solidification mechanism

For the issue, the effects of silver interlayer on microstructure and mechanical properties of 304 stainless steel/6061 aluminum alloy welded joint were investigated by utilizing double laser weldi ng in the paper. The results of the research showed that the interlayer was the prefabricated by silver, and the joint was formed well by dual laser welding process. Organizational analysis showed that the weld area was obviously divided into area A near the aluminum side and area B near the steel side. Area A was a silver-rich phase mixed with aluminum-rich phase, and area B was made from pure silver zone（B1） and austenitic zone（B2）. In addition, Fe-Al brittle intermetallic compounds didn’t appear in the weld seam. The results of mechanical properties showed that the fracture occurred in the pure silver zone of the joint, and the tensile strength was175.59 MPa, and the elongation after fracture was about 3%.关键词：silver interlayer;304 stainless steel;6061 aluminum alloy;laser welding;brittle metal intermetallic compound

The microstructure of the joint was analyzed and the mechanical properties of the joint were tested. The results show that both wire feed speeds can obtain welded joints without obvious defects, and the reinforcement increases slightly when the wire feed speed improves. The dendrites in the weld zone of welded joints with wire feed speed of 9 m/min are smaller than those with wire feed speed of 7 m/min. The microhardness distribution of the welded joint is "W" shaped. The average hardness of weld zone and bond are lower than that of the base metal. The minimum hardness occurs in the bond that is 3 ～4 mm distant from the weld center. When the wire feed speed is 7 m/min, the joint softening is more obvious. Both tensile fractures of the joints at these two wire feed speeds occur near the bond. The tensile strength and elongation of welded joints at wire feed speed of 9 m/min are higher than those at 7 m/min.The fracture form is a typical toughness fracture.关键词：5083 aluminum alloy;plasma-MIG welding;microstructure;mechanical properties;softening
