备注

当前国内外先进的焊接行业,均利用信息化、网络化等手段对焊接过程的参数进行监控采集以保证焊接质量,但是仅限于自动化焊接设备。手工氩弧焊电源属于非自动化设备,没有数据接口,难以对焊接过程中各参数进行监控、采集。针对手工氩弧焊主要的焊接参数(焊接电流、电弧电压、氩气流量),通过设计专用的手工氩弧焊的焊接参数采集盒,在采集盒中集成电流、电压、气体流量传感器,实现焊接过程焊接参数实时采集。同时,利用采集盒以太网口进行焊接设备联网集控,实现焊接过程焊接参数实时监控、实时采集和设备集中管控,保证产品焊接质量。

At present, the advanced welding industry at home and abroad uses information technology, networking and other means to monitor and collect the parameters of the welding process to ensure the welding quality, but it is limited to automatic welding equipment.The power source of manual argon arc welding belongs to non-automatic equipment and has no data interface, so it is difficult to monitor and collect various parameters during the welding process.Aiming at the main welding parameters(welding current, arc voltage and flow rate of argon gas)of manual argon arc welding, a special welding parameter acquisition box for the manual argon arc welding is designed, in which current, voltage and gas flow sensors are integrated to realize the real-time acquisition of welding parameters in the welding process.At the same time, the Ethernet port of the acquisition box is used for networking and centralized control of welding equipment, which realizes real-time monitoring, real-time acquisition of welding parameters and centralized equipment control in the welding process, so as to ensure the welding quality of products.
