Welding method based on quartz tuning fork crystal three-temperature-area nitrogen blowing

Abstract

The invention relates to the field of welding, in particular to a welding method based on quartz tuning fork crystal three-temperature-area nitrogen blowing. The welding method is characterized in that a nitrogen making machine is connected with one end of a drying machine through a pipeline, and the other end of the drying machine is respectively connected with a flow-limiting valve A, a flow-limiting valve B and a flow-limiting valve C through pipelines; the flow-limiting valve A is connected with a drying temperature area through a filter A, a heating wire A and a drying temperature area pipeline, and the other end of the heating wire A is connected with an adjustable converter A; the flow-limiting valve B is connected with a preheating temperature area through a filter B, a heating wire B and a preheating temperature area pipeline, and the other end of the heating wire B is connected with an adjustable converter B; the flow-limiting valve C is connected with a high temperature area through a filter C, a heating wire C and a high temperature pipeline, and the other end of the heating wire C is connected with an adjustable converter C; the drying temperature area, the preheating temperature area and the high temperature are provided with product track grooves. By the adoption of the technical scheme, due to the fact that chemical reactions among nitrogen molecules, tuning fork pieces and tuning fork base metal components do not easily occur at a high temperature, an oxidation process and dust pollution do not exist, and quality of products can be stable.

Description

technical field

[0001] The invention relates to the field of welding, and relates to a nitrogen-blowing welding method in three temperature zones of a quartz tuning fork crystal. Specifically, in the process of welding the tuning fork crystal, the tuning fork piece and the tuning fork base are fused and welded at high temperature, a new welding method. Background technique

[0002] In the field of quartz tuning fork crystal production, the traditional process of welding the tuning fork piece and the tuning fork base is that the heating wire heats the air and blows it on the welding fixture through the heating pipe airflow. Since the air contains water vapor, dust, and oxygen, this tuning fork crystal welding method , so that the quartz tuning fork piece is polluted, some dust particles will firmly adhere to the surface of the tuning fork crystal under the action of high temperature, and the oxygen and water molecules in the air will rapidly oxidize the welding point at high...
