Problems solved by technology
[0003] It can be seen that in the whole welding cycle process of traditional melting electrode welding machine, the arc length, arc voltage, arc current and arc temperature are constantly changing; therefore, in the welding process, the heat distribution between the welding wire and the base metal cannot be controlled Control, so that there are many welding defects in the welding process, such as welding spatter, welding porosity, lack of fusion, slag inclusion, uneven wire filling, etc.
In addition, the traditional melting electrode welding machine only has a single DC welding mode and a DC pulse welding mode, and its application range is narrow

A consumable electrode welder is provided with a high-frequency high-voltage arc starting module to realize high-frequency high-voltage starting of an arc, thereby preventing short circuit sparks generated by arc starting in a welding process. By arranging an arc-length feedback module and a wire-feeding control module, parameters such as an arc length and a wire-feeding speed can be controlled during a welding process, so that the consumable electrode welder has a welding speed and welding quality of a non- consumable electrode welder. Also disclosed is a welding method of the consumable electrode welder.
Description
technical field [0001] The invention relates to the field of welding machines, in particular to a melting electrode welding machine and a welding method thereof. Background technique [0002] The traditional melting electrode welding machine adopts contact short-circuit arc starting. When the short-circuit arc starts, there will be sparks splashing. After the short-circuit arc starts, under the action of the arc, the end of the welding wire forms a molten metal ball, such as figure 1 As shown in (a), at this time the arc length is very short, the arc voltage is very low, the current is very large, the arc temperature is low, and the energy of melting welding wire is large; as the amount of melting welding wire increases, the arc length becomes larger, and the arc voltage Also increases, the arc current decreases, the arc temperature increases, and the energy of melting the welding wire decreases. At this time, the droplet at the end of the welding wire is under the action of...
