Abstract

The invention discloses a cable solder wire for a CMT welding system. The solder wire comprises a central solder wire. The outer side of the central solder wire is provided with a spiral solder wire which is twined tightly around the central solder wire in a spiral manner. The outer side of the spiral solder wire is provided with a protection ring. The inside of the spiral solder wire is provided evenly with 4 subordinate solder wire groups. The subordinate solder wire groups are tangentially arranged. The inside of each subordinate solder wire group is provided with a first solder wire, a second solder wire, a third solder wire and a fourth solder wire. The fusion depth in the welding operation is deep. This structure can reduce the quantity of overlapping welding seams layers and can fundamentally increase the welding efficiency, reduce the production costs with negligible splashes. The high mechanical property of the welding seam and the tight binding structure of the solder wire stabilize the solder wire feeding process, enhances the welding property of the cable solder wire and makes the CMT welding system to render a better soldering effects.

Description

Technical field [0001] The invention relates to the technical field of welding wires, in particular to a cable type welding wire applied to a CMT welding system and a CMT welding system. Background technique [0002] In order to achieve high-efficiency welding, high-current welding technology is often used to achieve a large welding deposition rate, but with the increase of current, it is easy to cause metal landing and penetration in the first welding. In order to overcome the welding problem in the first welding, the cold metal transfer technology of C MT successfully combined the droplet transfer with the wire feeding movement, and realized the low heat input and spatter-free welding. When a transient short-circuit occurs, the power supply reduces the current to a very low level, and the heat input is almost zero, reducing unnecessary energy loss. However, the efficiency of the filling process in thick plates is very low, which is caused by factors such as limited welding wir...
