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.

焊接機器人也是一樣，不同的焊接姿勢（槍姿）對焊接成形的外觀也是一個決定性的因素。

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

像亞倫達機器人我們一般要求焊槍與焊接平面保持45°～60°左右，與焊縫那條線也保持在45°～60°左右。但前提讓焊槍避開焊接的產品和定位工裝。焊接姿勢不好會對焊接品質造成影響主要是因為兩個方面：一是氣體保護不好，二是送絲不暢。

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.

槍姿不合適會導致氣體保護不好，焊接會出現氣孔現象；槍姿不合適也會讓同軸電纜里的送絲太過彎曲而送絲不暢，會出現焊縫不均勻，斷斷續續的現象。如果在焊接過程中出現上述現象，槍姿雖然不是唯 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.
