【摘要】:復(fù)合熱源能夠發(fā)揮兩者各自的優(yōu)勢(shì),同時(shí)彌補(bǔ)兩者各自的不足。采用基于弧焊的金屬材料增材制造技術(shù)進(jìn)行墻體堆積過(guò)程中,層間停留時(shí)間成為影響焊接性能的一個(gè)重要焊接參數(shù)。使用熔化極氣體保護(hù)焊(MIG焊),通過(guò)改變不同的層間停留時(shí)間,對(duì)5356鋁合金增材制造過(guò)程進(jìn)行研究。研究表明,采用常規(guī)熔化極氣體保護(hù)焊進(jìn)行多層單道堆積墻體時(shí),對(duì)不同層間停留時(shí)間進(jìn)行控制,墻體可以獲得較好的力學(xué)性能。在最佳的層間停留時(shí)間下,采用低功率激光電弧復(fù)合熱源,通過(guò)適當(dāng)?shù)募す怆娀∧芰科ヅ?可以進(jìn)一步提高墻體的力學(xué)性能和墻體組織的均勻性。
[Abstract]:The composite heat source can give play to their respective advantages and make up for their respective shortcomings. The metal material augmentation manufacturing technology based on arc welding is used in the process of wall stacking. The interlaminar residence time is an important welding parameter affecting the welding performance. By changing the different interlayer residence time of MIG welding, the fabrication process of 5356 aluminum alloy is studied. When conventional gas arc welding is used for multilayer and single-pass stacking wall, different interlayer residence time can be controlled, and better mechanical properties can be obtained. Under the optimum interlayer residence time, The mechanical properties of the wall and the homogeneity of the wall structure can be further improved by using the low power laser arc composite heat source and the proper matching of the laser arc energy.
