The influence of different gun positions of welding robot on welding quality and appearance of a skilled welder is much better than that of a new welder. The main reason is that the skilled welder knows how much current, voltage and speed it needs to weld a product through his accumulated experience, and more importantly, the welding posture and method. Because the current and speed can be seen intuitively, but a suitable posture needs a long-term experience to decide.

焊接机器人也是一样，不同的焊接姿势（枪姿）对焊接成形的外观也是一个决定性的因素。

Welding robot is the same, different welding posture (gun posture) is also a decisive factor for the appearance of welding.

像亚伦达机器人我们一般要求焊枪与焊接平面保持45°～60°左右，与焊缝那条线也保持在45°～60°左右。但前提让焊枪避开焊接的产品和定位工装。焊接姿势不好会对焊接品质造成影响主要是因为两个方面：一是气体保护不好，二是送丝不畅。

Like the alenda robot, we generally require the welding gun to keep 45 degrees from the welding plane °～ sixty ° Left and right, the line with the weld is also kept at 45 °～ sixty ° about. But the premise is to let the welding gun avoid welding products and positioning tooling. Bad welding posture will affect the welding quality mainly because of two aspects: one is poor gas protection, the other is poor wire feeding.

枪姿不合适会导致气体保护不好，焊接会出现气孔现象；枪姿不合适也会让同轴电缆里的送丝太过弯曲而送丝不畅，会出现焊缝不均匀，断断续续的现象。如果在焊接过程中出现上述现象，枪姿虽然不是唯 一的因素，但也是需要排查的之一。

Improper gun position will lead to poor gas protection and gas hole in welding; Improper gun position will also make the wire feeding in coaxial cable too bent and the wire feeding is not smooth, which will lead to uneven and intermittent weld. If the above phenomenon occurs in the welding process, although the gun posture is not the only factor, it is also one of the key points to be investigated.
