Metal inert gas (MIG), Tungsten INERT GAs (TIG), laser and Electron beam (EB) cladding processes are used in cladding-based Additive manufacturing (AM). Only in the case of MIG, the raw-stock is fed axially into the molten pool resulting in the omni-directional cladding. In other processes, the raw-stock is fed off-axially into the molten pool resulting in deviation in the bead geometry from its actual trajectory and varying bead cross-section along the path. As the trajectories vary widely in cladding-based AM, it is required to maintain a consistent raw-stock feeding condition (namely, front, back or sides). Therefore, an auxiliary wire orienting mechanism has been developed which can be easily retrofitted with a conventional TIG cladding torch and CNC machine. The wire orientation angle is computed on-the-fly and hence the NC programme need not provide this information. Although this implementation was demonstrated for TIG, the same methodology holds good for laser and EB too.

金属惰性气体（MIG），钨惰性气体（TIG），激光和电子束（EB）熔覆工艺用于基于熔覆的增材制造（上午）。仅在使用MIG的情况下，才将原料轴向进料到熔池中，从而形成全方位熔覆。在其他过程中，原料被偏轴地送入熔池中，从而导致珠粒几何形状偏离其实际轨迹，并沿路径改变珠粒横截面。由于基于包层的增材制造的轨迹变化很大，因此需要保持一致的原料进料条件（即正面，背面或侧面）。因此，已经开发了一种辅助线定向机构，该辅助线定向机构可以容易地用传统的TIG包层焊炬和CNC机床进行改装。电线方向角是动态计算的，因此NC程序无需提供此信息。尽管已为TIG演示了此实现，但相同的方法也适用于激光和EB。
