Problems solved by technology

However, at present, there is no device that can automatically collect data and process the data to obtain line energy, and there is no monitoring equipment that can timely issue alarms based on the real-time line energy, so a large amount of data collection and equipment operation are required manually. It is not conducive to improving welding quality and work efficiency

Abstract

The invention provides an electric arc welding monitoring device and method. The electric arc welding monitoring device comprises a collection unit, a first processing unit, a first comparing unit and an alarm unit. The collection unit is used for collecting the attitude information of a welding gun, wherein the attitude information at least comprises the speed information of the welding gun. The first processing unit is used for obtaining the voltage and current of a welding power source, and calculating out the lineal energy of an electric arc by combining the voltage, the current and the speed information. The first comparing unit is used for comparing the linear energy with a preset energy range in a preset decision table and outputting an alarm signal according to a comparing result. The alarm unit is used for receiving the alarm signal and giving an alarm for responding to the alarm signal.

Description

technical field [0001] The present disclosure relates to the field of welding technology, in particular, to an arc welding monitoring device and an arc welding monitoring method. Background technique [0002] Welding is a very common manufacturing process in industry. Generally include arc welding, gas welding and so on. Among them, gas metal shielded welding is a welding method that uses the arc generated between the welding wire and the workpiece as a heat source to melt the metal. During the welding process, there are many factors that affect the welding quality, such as: welding line energy, welding gun posture and Among them, the line energy refers to the heat input by the welding power supply (or welding machine) to the weld seam per unit length during welding, which is mainly determined by the welding current, welding voltage and welding speed. [0003] In the prior art, in order to facilitate the control of welding quality, it is necessary to collect welding line e...
