Abstract

The invention relates to a testing device and method for a welding fume emission rate. The testing device comprises a data acquisition system and a process control system in the testing process for the welding fume emission rate, and comprises the composition parts of an industrial control computer, a data acquisition card, a motion control card, a current sensor, a voltage sensor, a relay, a wirefeeder, a stepping motor, a driver, a crossed sliding table, and the like. According to the system, measurement precision for technological parameters and timing precision for welding time during thetesting process for the welding fume emission rate are improved, stability of a welding technology during the testing process is improved, automatic measurement and control are achieved during the testing process, and a testing operation method is greatly simplified.

Description

technical field [0001] The invention relates to a data acquisition and control system for welding manufacturability research, in particular to a welding dust generation rate testing device and method. Background technique [0002] During the welding process, especially the welding fume generated during the arc welding process is one of the main pollutants. Long-term exposure to high-concentration welding fume environment will cause great harm to the health of welding operators. The concentration of welding fume in the air is closely related to the index of welding dust generation rate. Therefore, reducing the concentration of welding fume in the air by reducing the welding dust generation rate is an important way to improve the welding working environment. [0003] For gas metal arc welding, there are as many as 13 factors that affect the welding dust generation rate. In order to deeply study and analyze the influence of welding current, welding voltage, welding speed and ot...
