Abstract

Metal parts such as metal molds, etc. can be fixed firmly by the welding machine. And the arc melting device The right amount of fine welding powder or plate type welding material. Some are arranged on the metal part to be repaired. The first electrode of the welding machine is pressed. To the part of the welding powder or welding material A high pulse current of 300-1500 amperes is supplied to the electrode. First of all, it is a short time. 1 / 1000-4 / 1000 s to form a point-shaped welded material will melt. Liquid on metal parts Where the molten part is made in order to connect or continue with the metal Many of the welds are molten, so the molten weld mixes with the Orientation of the melted part A liquid or layer of the molten part is created and the welded part has the required thickness in the area. Required of the part to be repaired The mixed part of the metal to be repaired is encased in Inert gas atmosphere The first electrode of the arc melting machine is positioned adjacent to the mixed welding part, and the arc melting machine supplies the arc power. It is mixed for a short time to melt the welded metal again. The part being welded too much It is removed after the weld is solidified and the repair is finished by polishing.

Claims (5)
