WELDING DEVICE AND WELDING METHOD HAVING SELF-ADJUSTING WELDING WIRE ADVANCING SPEED

The aim of the invention is to control the feed of welding wire (8) to the weld (25) in a simple manner in a welding method. This aim is achieved, according to the invention, in that the electric potential (P) arising around the electrode (4) as a result of the welding current (IS) is tapped by mean...

Zusammenfassung:	The aim of the invention is to control the feed of welding wire (8) to the weld (25) in a simple manner in a welding method. This aim is achieved, according to the invention, in that the electric potential (P) arising around the electrode (4) as a result of the welding current (IS) is tapped by means of the welding wire (8), the welding wire advancing speed (vD) is controlled on the basis of the tapped potential (P), and an average welding wire advancing speed (formula (I)) arises as a result of the control. 为了在焊接方法中简单地调节焊丝(8)到焊接点(25)的供应，规定，借助焊丝(8)截取由焊接电流(IS)在电极(4)周围产生的电位(P)并基于截取的电位(P)实施对焊丝进给速度(vD)的控制并且通过控制产生平均焊丝进给速度
