摘要： Methods and apparatus for welding a component to fill a groove therein. The method entails simultaneously projecting an electric arc and at least first and second laser beams into the groove. The electric arc melts and deposits a filler material in the groove while the first and second laser beams are projected onto opposite first and second walls, respectively, of the groove. The axis of each of the first and second laser beams is oriented at an acute angle relative to the respective wall thereof.

摘要： A double-sided tribrid welding technique and apparatus for root pass welding of narrow groove welds. The welding technique utilizes three welding devices. A welding apparatus on a backside of the weld joint may strike an arc on the backside of the weld joint; a welding apparatus on a narrow groove side of the weld may strike an arc within the narrow groove weld joint, while the remaining welding apparatus is a laser that can help establish a keyhole as a common pool of molten metal at the root without burning through the root. Once the arcs are struck substantially simultaneously and the laser is energized, the welding heads move simultaneously, the arc welders assisting in maintaining pre-heat temperature, while minimizing distortion and cracking. Adjusting arc weld parameters provides deformation on completion of the root pass so as to compensate for distortion due to metal shrinkage in subsequent passes.
摘要翻译：一种双面三联焊接技术和窄槽焊缝根管焊接设备。焊接技术采用三种焊接装置。焊接接头背面的焊接设备可能在焊接接头的背面发生弧形; 焊缝的窄槽侧的焊接装置可以在窄槽焊接接头内发生弧，而剩余的焊接设备是能够帮助建立钥匙孔的激光器，作为普通的熔池金属池，而不会燃烧根。一旦电弧基本同时撞击并且激光器被激励，则焊接头同时移动，电弧焊接器有助于保持预热温度，同时最小化变形和开裂。调整电弧焊接参数在完成根部通过时提供变形，以补偿随后通过中金属收缩引起的变形。
