Background
In the nuclear power construction process, a large amount of equipment, pipelines, containers and steel structures are required, and the connection between the equipment is usually realized by using an electric welding mode, so that the welding is used as a necessary metal connection mode, and the quality of the welding directly influences the future operation safety. Before welding is carried out on site, welding process assessment work is carried out according to the requirements of corresponding rule standards, and welding parameters which can be used on site are formed through the process assessment work. Whether the welder is a direct operator of welding is an important link to ensure the welding quality or not is performed completely according to the determined welding process parameter range.
Before welding, a welder needs to check a welding process card (or called a process rule), the welding parameters are adjusted according to the parameters of the process card, a welding machine can only simply use a knob or a key to adjust welding current, but whether the current is in the process card range can not be controlled, real-time recording can not be realized for tracking, and partial welders often cause the welding parameters to exceed the process range due to improper operation or other factors (such as a wrong butt-welder knob), so that the welding quality is uncontrollable, poor and the like. In the related art, some wireless-controlled welding machines cannot meet the requirement that a large number of welding machines are used simultaneously in the same area and at the same time due to low communication reliability, and the welding machines are single in application range and can only be applied to common welding applications and cannot be applied to argon arc welding.
