Anonymous users2024-02-11If you simply weld from raw copper, you can choose silver wire welding for gas welding, such as Viodin 203 wire welding, and you can use silver flux paste welding when welding. However, this kind of welding requires more professional basic skills in gas welding operation.
The other is that it can be welded by DC argon arc welding, and when DC argon arc welding is welded, it is necessary to choose a welding wire suitable for brass argon arc welding, such as the brass argon arc welding wire of Viodin 204S for raw and raw copper welding, which is often used in argon arc welding of raw copper.
Precautions for the use of brass argon arc welding wire:
1. The oxides, oil and other dirt on the welding edge of the workpiece and the surface of the welding wire must be cleaned before welding, otherwise it will cause defects such as porosity and slag inclusion, and reduce the performance of the weld.
2. When argon arc welding brass or bronze, because the melting point of the parent itself is relatively low, please ensure that the welding of extra-thin pipe or plate materials can be welded under the premise that the molten pool can be formed normally.
3. When the thickness of the butt joint plate is less than 3mm, the groove is not opened; When the plate thickness is 3 10mm, open 60° 70°V groove; When the plate thickness is greater than 10mm, open the 60° 70°X groove. In order to avoid unwelded penetration, no blunt edges are generally left.
4. The workpiece must be preheated before welding. The plate thickness is less than 3mm, and the preheating temperature is 150 300; When the plate thickness is greater than 3mm, the preheating temperature is 350 500.
5. Use DC cathedral welding when TIG welding.

Anonymous users2024-02-101 yuan coin and copper key can be welded, this is a copper and alloy welding, this can be used low temperature brazing welding method, the most ideal is to choose the portable WE53 special liquefied gas spray gun as a heat source, the selection of low temperature wewelding 88C welding wire with wewelding88C-F flux auxiliary welding molding, the focus is on the flame do not deliberately burn the wire and flux when welding, but mainly rely on the parent heat conduction fusion welding wire formingJust pay attention to that. Read, perceive.

First, the fractured part is polished clean with an angle grinder. Grind out a certain taper. It can ensure that the welding penetration can be welded.

Anonymous users2024-02-05If it doesn't work, go and change it, you don't see much point in repairing it.
If you insist on welding repair, it is recommended to use silver-based brazing in terms of welding quality, and if it is argon arc welding, use brass argon arc welding wire and argon arc welding for spot welding.

Anonymous users2024-02-01Yes, but cooked copper and raw copper are different, and the welding method is not exactly the same, and the factory generally uses copper welding wire to heat and glue borax to weld.
