What materials are used for electrodes in medium frequency spot welding machines?

Some customers ask what material the electrodes used in the intermediate frequency spot welding machine are made of. Because the materials of the workpiece are different, the electrodes used are also different, so the material used as the electrode depends on the specific situation. Alumina copp... Read More

Medium frequency spot welding machine welding nut technology and method

The welding nut of the medium frequency spot welder is the realization of the projection welding function of the spot welder. It can complete the welding of the nut quickly and with high quality. However, several problems need to be solved during the projection welding process of the nut. There s... Read More

How does the cooling system of the medium frequency spot welding machine affect the welding quality?

The cooling system of the intermediate frequency spot welding machine is one of the important factors to ensure the stability of the welding quality. The fundamental reason is that the transformer, electrode, transistor, control board and other components will generate a lot of heat under high cu... Read More

Key points of welding quality control of medium frequency spot welding machine

There are generally two methods for inspecting the welding quality of medium frequency spot welding machines: visual inspection and destructive inspection. Visual inspection is performed on each item. If microscopic (mirror) photos are used for metallographic inspection, the welding nugget part n... Read More

What is the preload time of medium frequency spot welding machine?

The preloading time refers to the time from when we start the switch – cylinder action (electrode head action) to pressurization, which is called preloading time. The sum of the preloading time and the pressurizing time is equal to the time from the cylinder action to the first power-on. I... Read More

Why is chrome zirconium copper the electrode material of IF spot welding machine?

Chromium-zirconium copper (CuCrZr) is the most commonly used electrode material for IF spot welding machine, which is determined by its excellent chemical and physical properties and good cost performance. Electrode is also a consumable, and as the solder joint increases, it will gradually form a... Read More

Electrode pressure and welding time of IF spot welding machine

The PLC control core of IF spot welding machine can effectively control the impulse and discharge process, respectively adjust the pre-pressing, discharging, forging, holding, rest time and charging voltage, which is very convenient for standard adjustment. During spot welding, the electrode pre... Read More

Influence of welding time of IF spot welding machine on electrode pressure?

The influence of welding time of IF spot welding machine has obvious influence on the total resistance between two electrodes. With the increase of electrode pressure, R decreases significantly, but the increase of welding current is not large, which cannot affect the reduction of heat generation... Read More

Solution for insecure welding spot of IF spot welding machine

For the reason that the welding spot of IF spot welding machine is not firm, we first look at the welding current. Since the heat generated by the resistance is proportional to the square of the current passing through, the welding current is the most important factor to generate heat. The import... Read More

How to maintain electrode of IF spot welding machine?

In order to obtain high-quality welding spot quality, apart from electrode material, electrode shape and size selection, IF spot welding machine shall also have reasonable use and maintenance of electrode. Some practical electrode maintenance measures are shared as follows: Copper alloy shall be... Read More

Why is the current unstable during spot welding of IF spot welding machine?

We will encounter some problems when operating the IF spot welding machine. For example, the welding process is caused by unstable current. What is the cause of the problem? Let’s listen to the editor. Inflammable and explosive articles such as oil, wood and oxygen bottles shall not be sta... Read More

How to check the use of intermediate frequency spot welding machines?

The intermediate frequency spot welding machine needs to regularly inject lubricating oil into various parts and rotating parts, check the gaps in the moving parts, check whether the matching between the electrodes and electrode holders is normal, whether there is water leakage, whether the water...
