Whether the 3mm aluminum plate and the 3mm copper plate can be welded

If the 3 mm aluminum plate and the 3 mm copper plate are from the perspective of fusion welding, the traditional electric welding gas shielded welding cannot be welded, and even if welded, it will be very brittle.

If it is flame welding, it can be welded with low-temperature welding wire, and it can be welded with Vicudin ALCU-Q303 welding wire, but low-temperature welding is more picky about the structure, such as 3 mm aluminum plate and 3 mm copper plate are to be connected to the interface rather than the interface, or the corner interface can be.

1. A high current is required to open the oxide film of aluminum. As soon as the oxide film is opened, the aluminum is very soft and penetrates at a temperature of several hundred. Not to mention the 1 mm plate.

2. Welding: Welding, also known as "welding" or welding, welding, is a processing technology and connection method in which two or more materials (the same or dissimilar) are heated or pressurized, or both are used together to produce atomic bonding between two workpieces. Welding has a wide range of applications and can be used for both metals and non-metals.

Gas welding is fine, and when we practiced gas welding aluminum, we started by repairing small holes in the bottom of the can. 1mm, very good welding, we used M55 welding wire flux, the effect is good.

The common ones are: argon arc with pulsed tungsten electrode.

The best way: friction welding.

First, the plate that needs to be welded is polished, spot welded, and then fully welded.

A millimeter copper plate can be welded in the following ways:

1. VOD203 high silver welding teaser coarse wire, low working melting point, good operability, but relatively high price.

2. M51 welding wire at low temperature of 179 degrees, with M51-F flux welding, suitable for use in occasions with low strength requirements.

3. You can also consider the phosphor copper welding wire VOD202B, which is relatively cost-effective, and weld with solder paste.

In summary, it is necessary to take into account your specific welding requirements and select the appropriate welding and selling skin joints and materials.

It can also be welded with argon arc welding, and the effect is good.

Because argon is an inert gas, it is insoluble in metal and will not produce chemical synthesis, and at the same time, the welding wire does not pass through the current, the stool will not produce welding spatter, and the heat input is easy to control, which is the most recommended way to weld non-ferrous metals.

What the old man said above also makes sense, and he recommended several flame brazing brazing brazing filler metals, but the flame brazing needs to heat the seepage area is too large, and the difficulty of welding operation is relatively large, and the heating temperature of the workpiece and the temperature of brazing filler filling are not easy to master.

Millimeter copper plate is brazed and welded, using flame brazing, and there are several welding methods to choose from.

1. The welding of soft brazing metal at a low temperature of 179 degrees is heated by liquefied gas porous spray gun as the heat source, and the Wewelding M51 welding wire is welded with the flux of M51-F, which is more suitable for small welding joints.

2. Hard brazing metal can also be used for welding, if the copper plate is a copper plate, use the solder of Viodin 202A to braze, and the liquefied gas spray gun as a heat source for heating, do not use solder powder, if it is a brass plate, use the same welding wire, the same heating heat source, just need to use the solder paste with Viodin 201-F.

3. Through the welding method of fusion welding, argon arc welding, if it is copper, use copper argon arc welding wire Wei Ouding 204, welded with DC argon arc welding machine, if it is brass, use brass argon arc welding wire with diameter specifications, weld with AC argon arc welding, and then use DC without AC.

1. The low-temperature M51 with M51-F welding wire is operated in the environment of 179 degrees at a working temperature, and the affinity of the high-joint material of the welding section is relatively good, and it is mostly used for welding in the case of particularly strict deformation control requirements or particularly thin.

2. WE53 low-temperature aluminum electrode for the welding of 7 series of aluminum alloys, the welding working temperature is 380-400 degrees, the advantage is that there is no need to assist any flux welding when welding, so as to prevent some flux residues in the welding process, and the welding strength is very high, which can solve the welding of 3 series aluminum alloys and castings, or pressed old castings.

3. Q303 low-temperature aluminum welding wire also reflects some special advantages for the weldability of aluminum alloy, which is the narrow gap welding with a not very good angle.
