Abstract

The invention relates to the field of carbon dioxide welding, in particular to a warning device for preventing welding missing and welding lack during carbon dioxide welding. The warning device for preventing the welding missing and the welding lack during the carbon dioxide welding comprises a reset switch, a first travel switch, a second travel switch, a first intermediate relay, a second intermediate relay, an audible and visual alarm, a welding length detection signal device, a programmable logic controller (PLC) and a switch power supply. The first travel switch, the second travel switch, the first intermediate relay, the second intermediate relay, the welding length detection signal device and the switch power supply are respectively and electrically connected with the PLC, the first intermediate relay is electrically connected with a welding machine air valve control-end coil, and the second intermediate relay is electrically connected with the audible and visual alarm. The warning device has the advantages of helping an operator to quickly judge whether product weld joints are missed or not and the welding length is insufficient or not in the production process, and accordingly avoiding the weld joint welding missing and insufficient welding length.

Description

technical field [0001] The invention relates to the field of carbon dioxide welding, in particular to an alarm device for preventing carbon dioxide welding from missing or missing welding. Background technique [0002] At present, in the production process of carbon dioxide, although the welding length has been indicated in the process requirement document, the welding seam of the product is missing due to unskilled operators and lack of concentration, and the welding length is not enough. Missed welding and less welding length have a serious impact on product quality. In order to avoid missing welds and reduce the welding length of the product, the operator must check 100% and the inspector must recheck 100%, which is a waste of time. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems, and provide an alarm device for preventing carbon dioxide welding from missing welding and less welding. [0004] In order to ...
