  hybrid welding
An additional application of interest for hybrid welding on the panel line is the joining of stiffeners to panel.
      
As the gap width increases, the bead width increases in hybrid welding, while the bead width is almost unchanged in laser welding.
      
Future efforts will focus on further optimizing the hybrid welding process for joining stiffeners to panel.
      
Hybrid welding can provide uniform beads even when the welding speed is high because droplet transfer from the wire takes place in a very short cycle.
      
In hybrid welding, the voltage oscillates within the range of 0 to about 20 V at high frequency.

  composite welding
Composite welding occurs as various flakes are joined to one another by random overlappings resulting in a single compound flake.
      


YAG laser/MAG arc hybrid welding of 1Cr18Ni9Ti stainless steel was investigated in this paper. It shows that the hybrid welding, which a YAG laser hybrids with MAG arc characterized by short circuiting transfer, will present the synergistic action using proper welding parameters. The hybrid weld depth is larger than total depths of laser welding and arc welding-and is 2 times more than laser welding depth. It also shows that hybrid weld width is similar to arc weld width. Corresponding to this synergistic effect,...

YAG laser/MAG arc hybrid welding of 1Cr18Ni9Ti stainless steel was investigated in this paper. It shows that the hybrid welding, which a YAG laser hybrids with MAG arc characterized by short circuiting transfer, will present the synergistic action using proper welding parameters. The hybrid weld depth is larger than total depths of laser welding and arc welding-and is 2 times more than laser welding depth. It also shows that hybrid weld width is similar to arc weld width. Corresponding to this synergistic effect, hybrid welding current is higher than arc welding current and hybrid welding voltage is lower than arc voltage. When the arc welding current is overlarge or the welding speed is overlow, the synergistic effect of hybrid welding doesn' t occur, and hybrid weld depth is smaller than the laser weld depth. Using suitable laser power and welding current the hybrid arc stability as well as weld width vary little with defocus distance of laser beam, but the defocus distance that can produce the largest weld depth is different to that of laser welding. And laser leading can produce higher weld depth than laser trailing during hybrid welding. When the distance between laser act point and arc act point is 0.5 mm, hybrid welding of both laser leading and laser trailing can obtain the highest weld depth.

利用YAG激光焊头和MAG焊枪旁轴复合进行了1Cr18Ni9Ti不锈钢的激光电弧复合焊工艺研究。研究表明:影响复合焊过程的主要工艺参数有激光功率、焊接速度、焊接电流、电弧电压、激光焦点位置、两热源的间距和相对于焊接方向的排列方式等;在一定的焊接工艺条件下所研究的YAG/MAG复合焊具有协同效应。电弧参数测试也表明,当激光与电弧复合的协同效应存在时,复合焊电流高于电弧焊,而电弧电压降低;若电弧采用过大的焊接电流与激光复合,尤其是在较低的焊接速度时,复合焊过程体现不出协同效应,复合焊熔深反而低于激光焊熔深。复合焊激光焦点位置变化对电弧稳定性和熔宽影响小,但获得最大熔深的焦点位置不同于激光焊。激光前置焊比激光后置焊获得的熔深大,两种条件下均在两热源间距为0.5mm时熔深最大。

Ti foil combined with Cu or Ni foils was used as insert metals to join TiAl intermetallic and Inconel 718 employing transient liquid phase (TLP) bonding technique. The effect of dwell time at bonding temperature on the interfacial structures of the joints was investigated. Results showed that defect-free joints was fabricated, but the liquid formation processes and mechanism of Ti-Cu and Ti-Ni insert metals were quite different. Some sublayers were found in the joined zone because the alloyed elements which diffused from Inconel 718 alloy segregated at the interface between Inconel 718 alloy and joined zone. Morphologies and hardness profiles of the joined zones showed that the joint produced using Ti-Ni insert metals could isothermally solidify much faster than that produced using Ti-Cu insert metals under the experimental conditions.
