Problems solved by technology

[0004] 2. Pressure welding - the welding process must exert pressure on the weldment;
[0006] In the prior art, there is always a lot of air entering the weld seam during welding, which causes many air bubbles to be generated in the weld seam, resulting in a decrease in the welding strength of the weldment; moreover, these weld seams are always detected after welding, and at this time Adjusting the weld is not only very difficult, but also easy to damage the weldment

Abstract

The invention discloses a welding gun nozzle improved structure specific to weld penetration force. The structure comprises a barrel. A cylindrical contact tube, a wire feeding mechanism and a controller are arranged in the barrel. The wire feeding mechanism is located between the contact tube and the controller. The end face, away from the wire feeding mechanism, of the cylindrical contact tube is provided with a welding wire rod and two ultrasonic probes. The welding wire rod is connected with the wire feeding mechanism through a welding wire. A through hole is formed in the welding wire rod. The through hole and the welding wire are matched in diameter, and the central line of the through hole coincides with the axis of the cylindrical contact tube. The ultrasonic probes are symmetrical about the axis of the cylindrical contact tube and are connected with the controller. A button input module and a display module are arranged on the outer side of the barrel. The button input module and the display module are connected with the controller. The purpose of welding and detecting a welding nozzle of welding bubbles at the same time is achieved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an improved structure of a welding torch nozzle aimed at penetration. Background technique [0002] Welding: also known as welding and welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. Welding achieves the purpose of joining through the following three ways: [0003] 1. Fusion welding-heating the workpieces to be joined to make them partially melt to form a molten pool, and then join after the molten pool is cooled and solidified. If necessary, fillers can be added to assist; [0004] 2. Pressure welding - the welding process must exert pressure on the weldment; [0005] 3. Brazing—Using a metal material with a lower melting point than the base metal as the solder, using the liquid solder to wet the base metal, filling the gap, and interdiffusion with th...
