Problems solved by technology
However, most of the traditional monitoring methods are based on the operation of the operator according to the requirements of the welding process. In the actual welding operation using this method, due to human operation, it is difficult for the operator to meet the requirements stipulated by the welding process. In addition, the operator pursues Welding efficiency and other reasons to carry out over-standard operations, resulting in affected welding quality
In order to standardize the management of welding operations, it is necessary to set up special supervisors for on-site monitoring, resulting in unnecessary waste of human resources
At the same time, if the welding current does not meet the requirements and does not check in time, the operator will continue to weld, resulting in only destructive testing after the body is completely welded
Affect welding quality and reduce production efficiency

Embodiment Construction
[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.
[0018] like figure 1 Shown, a kind of automobile sheet metal welding current monitoring method, this method is to install the electric current transformer on the wire of manual welding torch to judge the size of real-time welding current, increase the controller that is electrically connected with the electric current transformer at the same time, through the controller The current induced by the current transformer is compared and judged with the preset current, so as to achieve the purpose of monitoring the welding current. The specific method mainly includes the following steps:
[0019] (1) Install a current transformer on the connecting wire of the manual welding torch, and electrically connect the controller with the current transformer;
[0020] (2) Preset the welding current fo...

The invention discloses a method for monitoring a welding current of a car metal plate. The method comprises the steps of: installing a current transformer on a lead of a manual welding gun to judge the size of the welding current in real time; adding a controller which is electrically connected to the current transformer; contrasting and judging the current sensed by the current transformer and the pre-set current through a controller; and when the sensed current exceeds a preset current value, giving an alarm by the controller to indicate that the welding is unqualified and checking or re-welding needs to be carried out in time to avoid destructive detection of a well-welded car body. The method for monitoring the welding current of the car metal plate is simple, not only can ensure the welding quality, but also can save manual cost as the welding current is monitored in time by combining the current transformer with the controller, and improves production efficiency greatly.
Description
technical field [0001] The invention belongs to the field of welding technology and relates to a method for monitoring welding current of automobile sheet metal. Background technique [0002] Welding is a process and connection method that produces interatomic bonding between two workpieces of the same sex or opposite sex by heating, pressure, or both. Welding is used in a wide range of applications, both on metals and non-metals. In order to ensure the welding quality, the welding process is generally formulated by the process department, and welding parameters such as welding current and welding voltage are specified according to different welding conditions. The operator should follow the welding process requirements during welding operations, otherwise it will lead to welding defects and cause Welding quality is poor. [0003] In the welding process of thin-walled sheet metal parts, the control of the welding current is extremely important. For example, in the sheet me...
