Description

Bead cleaner that automatically replenishes electrolyte

The invention relates to the field of welding, and in particular to a bead cleaner which automatically replenishes an electrolyte.

Metal welding is an indispensable process in the industrial field. Common welding processes usually use arc welding such as argon arc welding and gas shield welding. During the welding process, there is a conversion process in which the metal is heated from solid to liquid and finally cooled to solid state. Gas protection or flux protection is used in the welding process, but the process of solidification after heating of the metal is inevitably oxidized, which makes the weld bead appear black and unclean. These oxidized metal layers are not easy except for the appearance. Continue to rust and oxidize, so on some high-demand workpieces, it is necessary to carry out the bead cleaning process. There are two general cleaning methods, one is grinding, using various types of grinding machines to grind belts, grinding wheels and other physical friction. The oxide layer is removed; the other is a special bead cleaning machine. As shown in the first figure, the bead cleaning machine generally includes a DC power source 1, a cleaning gun 2, a power output line 3, and a ground wire 3a, which will be cleaned. After the metal workpiece 4 is fixed by the ground clamp 5 at the end of the ground wire 3a, the tip 6 of the cleaning gun 2 is generally covered with a copper head to cover the absorbent cloth or the absorbent cotton, or a carbon brush or the like is used. The design of the conductive and water absorbing effect makes it easy to take the electrolyte. Under the power supply of the DC power supply, the cleaning gun 2 contacts the metal workpiece 4 with the gun head 6 to form an electrolytic circuit. This redox process can make the oxidized metal on the metal workpiece 4 into an ion. The state enters the electrolyte, causing the oxide attached to the metal surface to fall off. However, the traditional bead cleaning machine cannot automatically replenish the gun head 6 and must be repeatedly picked up by the gun head 6. The electrolyte can be electrolytically cleaned, the operation is cumbersome, the efficiency is low, and a bottle of electrolyte is placed next to the cleaning, and the electrolyte is easily knocked down to pollute the surrounding environment.
