Carbon dioxide gas shielded welding device and method

Abstract

The invention discloses a carbon dioxide gas shielded welding device and method, and relates to the technical field of welding devices. The device comprises a vehicle body, a control body, a wire feeding mechanism and a welding mechanism, the control body and the wire feeding mechanism are mounted on the vehicle body, the wire feeding mechanism is positioned in one side of the control body, a wirefeeding disc movably sleeves one side of the wire feeding mechanism, a welding wire protective tube fixedly sleeves the other side of the wire feeding mechanism, and the welding mechanism comprises awelding arm. According to the carbon dioxide gas shielded welding device and method, a rotating ring on an adjusting ring sleeve is adjusted to control rotation of a wind screen cover, so that the wind screen cover screens wind for a welding joint, influence of air flow and wind, generated by opening a window for ventilation or starting a fan or air conditioner for cooling during carbon dioxide gas shielded welding in the indoor environment, on welding can be avoided, and the problem of unsatisfied welding effect is overcome.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a carbon dioxide gas shielded welding device and a welding method. Background technique [0002] Carbon dioxide gas shielded welding is one of the welding methods. It uses carbon dioxide gas as the shielding gas for welding. The operation of carbon dioxide gas shielded welding is simple, suitable for automatic welding and all-round welding, and its cost is low. Carbon dioxide gas is easy to use. Production, widely used in enterprises of all sizes. [0003] However, the wind resistance of carbon dioxide gas shielded welding is poor, and it needs to work in a windless indoor environment. When carbon dioxide gas shielded welding is working, iron filings are flying seriously, so ventilation is required, and in some special indoor environments, such as summer When the temperature is high, when it is necessary to open windows for ventilation or start fans, air conditioners a...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a carbon dioxide gas shielded welding device and a welding method, which has the advantage of being convenient for shielding from the wind during welding, and solves the problem of poor wind resistance of carbon dioxide gas shielded welding, which requires working in a windless indoor environment. When welding is working, the iron filings are flying seriously, and ventilation is required, and in some special indoor environments, such as high temperature in summer, when it is necessary to open the window for ventilation or start the fan or air conditioner to cool down the operator, there will inevitably be airflow and wind. As a result, it will affect the welding work of carbon dioxide gas shielded welding, resulting in poor welding results
