Argon arc tester principle

Argon arc tester is a device used to test the weldability of materials. Its principle is based on the fact that the material will undergo physical and chemical changes under the action of the arc, thereby affecting its welding performance. Specifically, the argon arc tester applies an arc on the surface of the material to cause oxidation, melting and other reactions on the surface of the material, and then judges the welding performance of the material by detecting information such as the physical properties and chemical composition of the material surface.

During the use of the argon arc tester, the arc's high-temperature, high-energy plasma is formed by high-voltage pulses between the electrodes. When an arc is applied to the surface of a material, the substances on the surface of the material will be affected by high temperature and high pressure, causing reactions such as oxidation and melting. These reactions will cause changes in the physical properties and chemical composition of the material surface, thereby affecting the welding performance of the material.

By detecting these changes, the argon arc tester can evaluate the welding performance of the material, such as deposition rate, penetration depth, heat affected zone and other parameters. These parameters can be used to evaluate the weldability of materials, thereby providing reference and guidance for the welding process.
