Aluminum Welding Wire 5356 Production Process


Aluminum welding wire 5356 has been widely used. According to the introduction of the world's leading aluminum alloy welding wire production process, welding wire can be simply divided into the following parts:

1. Raw material preparation; 2. Wire drawing; 3. Heat treatment; 4. Surface scraping; 5. Sizing and drawing; 6. Packaging

The six links are well controlled and can provide high-quality aluminum alloy welding wire.

The specific process is as follows:

Pay-off machine, a tension machine, a straightening frame, a scraper, a tension machine, a water tank wire drawing machine-tension machine, a scraper machine, a tension machine, a single-head wire drawing machine, a tension machine, a wire wiper (cleaning)-ultrasonic cleaning tank, a Boiled water washing tank-wire grazing machine (coating)-drying device-traction machine-tension machine and wire take-up machine.


1. Disc

First, the basic ingredients of this element must be within the scope of AWS 5.10, but this is not enough. A more realistic approach is to first analyze the composition of the many well-known brands of welding wire around. world.

Analyzing all elements is not an easy task. In order to analyze the content of non-metallic elements such as O, H, Si, etc., the hydrogen element must be determined using special equipment such as gas chromatography or mercury titration (mercury is poisonous). The new oxide layer formed by foreign matter needs to be removed before testing.

Other metallic elements can use direct-reading spectrometers, but must be well calibrated. Otherwise, the light metals AL and Mg are not easy to detect.

A critical first step is knowing exactly what the world's leading welding wire is made of. Don't think that only the elements are shown in the material book.

There is also an exact understanding of the level of control on inclusions. A scanning electron microscope (SEM) can be used to find and measure these inclusions, such as certain oxides. If you cannot accurately understand and obtain qualified raw materials, all subsequent efforts will be useless.

First of all, the work described above must be limited to what is legally permitted, since the composition of the welding wire has been patented several times.

The shape of the disc is usually 9.5mm to ensure good roundness and surface quality.


2. Drawing


The cross-section decreases during stretching, and the material undergoes compressive plastic deformation, resulting in work hardening.

In order to improve production efficiency, it is always necessary to increase the drawing speed. Therefore, in order to produce 1.2mm wire, it is crucial to reduce the diameter from 9.5mm to an intermediate diameter. Drawing will increase the strength of the wire and reduce its plasticity.

Microscopically, the internal defects of the welding wire gradually increase, such as dislocation density. Therefore, at this time, it is crucial to control the inclusions, otherwise the large plastic deformation will lead to fracture.

To get better data for this process, you can do some experiments, such as drawing to 2.8mm at a time. Numerical simulation can also be used for finite element analysis, e.g. with elastoplastic analysis software such as Autoform, which can increase efficiency and reduce testing costs.

Compression molding limits can be displayed on a computer. The quality of the inner surface of the drawing die is very critical and must be smooth and lubricated, otherwise surface damage and out-of-roundness will inevitably result.

Therefore, the daily maintenance of the drawing die is also very important.

It is necessary to know exactly whether the inner surface of the drawing die is intact or not. A magnifying glass with a certain magnification must be used to check and formulate standard specifications.
