Description

Technical Field

[0001] The utility model belongs to the technical field of welding machine nozzles, in particular to an adjustable composite welding machine nozzle. Background Art

[0002] The welding nozzle is one of the important components of welding equipment. It is mainly used to control the gas flow and the transfer of molten droplets during welding. Since the size of the nozzle orifice directly affects the formation of the welding molten pool and the gas flow rate, a fixed nozzle diameter may cause the molten pool to be too large or too small, which in turn affects the fusion and strength of the weld and causes welding defects such as pores and cracks. At the same time, different materials and different welding positions have different requirements for nozzles. Fixed nozzles may not be able to adapt to different welding tasks, resulting in unsatisfactory welding results. This inadaptability will make it difficult for operators to ensure the uniformity and controllability of welding when facing different workpieces. Therefore, we hope to design an adjustable composite welding nozzle to solve this problem. Utility Model Content
