How to weld the aluminum water tank, what method to weld the aluminum water tank of the car

How to weld the aluminum water tank, the most important thing is to master the heating temperature, for example, the thickness of the flat tube of the water tank is only millimeters, and the thickness of the motherboard at the root is about millimeters. When heating, focus on heating the motherboard, do not heat the thin riser part, the temperature of the motherboard is enough, the temperature of the thin riser is enough by heat conduction, in addition, you can choose the solder with a lower temperature when welding, such as the welding wire of wewelding M51 at a low temperature of 179 degrees with the flux of 51-F, which is also to minimize the influence of temperature.

What is the best welding for aluminum tank welding, in fact, depends on the individual's own technical conditions.

For example, the most economical is the welding of ER4047 aluminum-silicon low-temperature welding wire with the imported flux powder of aluminum welding powder Wewelding53-F, but this is more difficult for most operators, and even for the master to weld the root of the water tank.

If you are a novice, then you can consider low-temperature aluminum welding wire, such as 179 degree WeWelding M51 welding wire with M51-F flux welding, which is more suitable for needle hole leakage, and it really can't burn the mother.

If you are a novice, you can also use the 430 degree Viodin 303 or 385 degree Viodin 53 low-temperature aluminum wire welding wire with higher strength.

1. Argon arc welding, the future development trend, its advantages are that the weld is fine, the flatness is good, and the yield is higher. 2. Steam welding, a welding method that has been used for a long time, has the advantages of small investment and can be mastered in a short time, and the disadvantage is that there is often water leakage and water seepage in the sand hole. 3. Soldering, suitable for thinner aluminum plate welding.

The conventional welding of aluminum water tank is the following welding square head and skills:

1. Domestic low-temperature 4047 aluminum-silicon welding wire.

Melting point 580-620 degrees), with low-temperature aluminum welding powder welding, this method is more suitable for traditional aluminum tank welding, the master of hanging aluminum water tank welding brand generally uses more welding methods, the cost is relatively low, but the welding root still has some limitations and considerable difficulty.

2. Low-temperature Viodin 303 low-temperature aluminum welding wire welding (melting point 430 degrees), oxygen acetylene can be used.

As a heat source welding, it can also be used for gas welding with a single gas source, this welding method is more suitable for novice welding operations, without the need for solder powder, although the cost will be higher, but the average cost is negligible for the value of repair.

3. Low temperature 179 degrees low temperature aluminum welding wire M51 with M51-F flux, this welding method is characterized by low temperature, absolutely low, less than 200 degrees, so anyone welding will not burn out the aluminum tube, generally most of them are used for needle eyes.

Small porosity defects, and even some parts that are not convenient for disassembly and assembly, can be welded as long as the water is discharged, but this is generally not suitable for welding long cracks because the temperature is too low, and the front welding parts are afraid of being affected when welding back.

4. Low temperature 385 degrees of low temperature aluminum welding wire wewelding53 welding wire with 53 special root brush welding, the characteristics of this welding wire is that it subverts all aluminum welding methods, is welded with the root brush, and is not picky about the parent material, so the general intercooler.

Or if the large tank crack is very close to the inside, this comparison is advantageous.

The low-temperature aluminum welding set is used to weld, which is introduced in detail in the welding application of the aluminum water tank of Viodin, which is more suitable for novices to use and operate.

The welding method of the automobile aluminum water tank can be welded by using the Weiodin low-temperature aluminum welding set, which is introduced in detail in the welding application of the aluminum water tank of Weiodin, which is more suitable for novices to use and operate.

Tools: WE53 special liquefied gas porous spray gun (generally for thin parts), or oxygen acetylene gas welding gun (generally for thick parts).

Material selection: The water tank of the car includes the riser and the root, and the water tank riser of the large truck is welded with Viodin 303 with WE53 special hole spray gun, and the root of the large truck water tank and the intercooler are welded with Veodin 53 welding wire with oxygen acetylene, or cutting gun.

Dear, that's flux solvent.

Hope it helps, dear. Have a great day.

I'm sorry to keep you waiting. The welding method of the pressurized water tank is as follows:1

When the finished stainless steel water tank is argon arc welded, the back of the weld should be supplied with air in advance. The flow rate should be increased appropriately. After the air is discharged, the flow rate should be gradually reduced.

During the welding process, argon gas should be continuously filled into the pipeline. When the welding is stopped, the gas is stopped delayed, so that the weld is fully protected. In addition, special attention should be paid to the fact that the welding of the combined stainless steel water tank can only be carried out after the air is exhausted, otherwise the protective effect of argon filling will be affected.

2. The argon flow rate should be appropriate. The flow rate is too small, the protection is not good, and the back of the weld of the finished stainless steel water tank is easy to oxidize; If the flow rate is too large, the eddy currents generated during the welding process will bring in air, and the protection effect will be poor. At the same time, it will cause defects such as depression at the root of the weld, which will affect the welding quality.

3.The argon population should be placed as low as possible in the enclosed area, and the vent holes should be placed in the location of the enclosed area. Since argon is heavier than air, it is easy to ensure the concentration of argon gas from a lower position, and the argon charge has a better protection effect.

4.In order to reduce the loss of argon gas from the butt gap in the pipeline, affect the protection effect of the finished stainless steel water tank and increase the cost, the tape can be pasted in the joint gap before welding, leaving only the length of the welder to weld once in a row, and removing the tape during welding.

Welding, also known as welding, splicing, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding achieves the purpose of bonding through the following three ways:

1. Fusion welding - heating the workpiece to be joined to make it partially melt to form a molten pool, the molten pool will be joined after cooling and solidifying, and the melt filler can be added to assist if necessary, it is suitable for the welding of various metals and alloys, without pressure.

2. Pressure welding - the welding process must apply pressure to the weldment, which belongs to the processing of various metal materials and some metal materials.

3. Brazing - using metal materials with lower melting point than the base metal as brazing metal, using liquid brazing metal to wet the base metal, filling the joint gap, and diffusion with the base metal to achieve link weldments. It is suitable for the welding of various materials, and also suitable for the welding of different metals or dissimilar materials.

There are many types of energy** in modern welding, including gas-modified closed hall flames, arcs, lasers, electron beams, friction and ultrasonics.

Then use the electrode with solder powder to scratch the welding test at the place to be welded, if the temperature is up, the electrode will melt to the welding place like water. If you find that it is not sticky, remove the welding rod and continue to heat the basepiece. (Do not deliberately use the flame to burn the electrode during the welding process, or keep it in a vertical burning state.)

The electrode will melt at the temperature uploaded at the bottom. If you are careful, you will find that the welding rod is melted from the bottom first). If you weld thick aluminum parts, you should use a cutting gun (or plum blossom welding nozzle) to increase the flames, preheat the base parts, and then use the welding rod to stick the welding powder for many times to test welding.

If you don't feel the temperature yet, you can try to burn through the weld first, and then weld through the burn-through area. The purpose of this is to know the limits of warm-up. Then you will know what to do.

Solder powder storage: This solder powder has moisture absorption characteristics, it is best to separate a small amount when using, and then divide it after use. The rest should be kept sealed in a timely manner. Avoid long-term open use of the whole pack. As usual, open solder powder will eventually turn into mud due to moisture absorption, and then turn into water.

First of all, clean the place that needs to be welded, such as cleaning with acid or other items, then hold the welding gun in the left hand, take the tin bar in the right hand, ignite and heat the welding place, put the tin bar on after the temperature is appropriate, and then gently apply the solder to the welding part with flux, and the uneven place of the weld can be heated again, probably so many basic steps, and the rest have to rely on their own practice.
