Reasons why small spring steel sheets must be welded with a small medium frequency spot welder
Release time:2022.04.10
Summary of information:
Small spring steel pieces must be welded with a small medium frequency spot welder, of course based on its characteristics and advantages. If you have tried an AC spot welder, you will be more certain that only a small power medium frequency spot welder can weld spring steel firmly. This has an important relationship with the chemical composition of spring steel.
Small spring steel pieces must be welded with a small medium frequency spot welder, of course based on its characteristics and advantages. If you have tried an AC spot welder, you will be more sure that it only has low power.Medium frequency spot welding machineIn order to weld spring steel firmly, this has an important relationship with the chemical composition of spring steel. Let’s take a look at the material properties of the workpiece and the performance of the welder one by one.
1. Characteristics of spring steel
1. Good elasticity, high tensile strength and high yield-to-strength ratio
2. Good anti-relaxation performance, good anti-fatigue performance, good hardenability,
3. Heat resistance, low temperature resistance, oxidation resistance and corrosion resistance
4. Carbon spring steel has a high carbon content, generally in the range of 0.6-0.9%. Silicon-manganese is added to alloy spring steel to increase strength. The manganese pole is easily brittle during welding. Various annealing, normalizing, tempering and quenching treatments are required.
We can see from point 4 above that its carbon content is relatively high. Generally, low carbon steel is less than 0.25%. If it is higher than that, it is called high carbon steel. The welding performance is relatively poor and requires much more power than low carbon steel to weld firmly. When manganese is added, it must be quenched and tempered while welding, and this function is only available in programmed medium frequency spot welders. In addition to this function, of course there are other functions:
1. The large current passes through the small electrode tip and instantly penetrates the workpiece for welding. The thermal impact is small and the workpiece does not deform or discolor after welding.
2. Energy saving, 30% energy saving than ordinary welding machine
3. Fast speed, millisecond speed. Compared with other spot welding machines, the welding time is shortened by 10 times when welding the same workpiece, and it is non-inductive welding.
4. High precision: 20-80 times that of ordinary spot welding machines
5. Suppress splash, precise current rising slope and time control, suppress spark splash by 90%
6. It has a wide welding range and can be tempered and welded on the basis of other welding machines.
7. Small impact on the power grid, three-phase power supply, power factor as high as 95-98%, no power compensation equipment required
8. The degree of automation is high. PLC and robots are connected to the production line, which is convenient and easy.
9. Precision and intelligence, the whole machine is small and exquisite, specially designed and manufactured for welding 3-layer boards, small thin parts and precision parts
10. DC output: Reduces welding induction energy loss. The continuous heat supply generated by the flat output current causes the nugget temperature to continuously rise. The same effect requires only lower welding current and pressure.

In recent years, spot welding machine butt welding machine manufacturers have been constantly seeking breakthroughs in automatic spot welding machines and medium frequency spot welding machines. Sometimes the reality is very disappointing. For example, for strip steel, iron sheets, and low carbon steel plates, everyone still prefers to choose economical and affordable spot welding machines.
Those spot welding machines mainly include foot-operated spot welding machines and pneumatic spot welding machines, both of which can suppress spatter and make welding firm. The foot-operated spot welder uses the power of the foot to drive a lever to weld, while the pneumatic spot welder uses the power of compressed air to weld with less effort.
There are many styles and colors of foot-operated spot welding machines. Which one is the most popular?
Its style is as follows:
The advantages are as follows:
1. Economical and labor-saving: adopting a reasonable spring foot pedal lever structure to save time and labor.
2. Less sparks and spatters: The welding current increases in a balanced manner, suppressing sparks by 90% and avoiding spatters during welding.
3. Large welding range: the welding current and heat are adjustable in 99 levels, and the lower limit of the thickness of the welding workpiece is doubled.
4. One-button operation: Just step on the pedal.
5. Intelligent control: The parameters are easy to set and will self-detect, diagnose and protect at the same time.
6. Easy maintenance: Electrical circuits are highly integrated and intelligent. Semiconductor thyristors replace contactors, which means there is no contact connection and less maintenance.
7. Safe and reliable: high current, voltage <3.58V, smaller than 5V mobile phone charger, safe and guaranteed.
8. Long service life: Steel box shell and high-quality all-copper transformer extend the service life to more than 20 years.
The style of pneumatic spot welding machine is as follows:
The advantages are as follows:
1) Pneumatic drive saves time and effort
2) Water cooling, automatic production line continuous welding without overheating, long service life
3) The electrode loss is more than 3 times less and does not need to be replaced frequently.
4) The current is large, the voltage is <10V, and safety is guaranteed.
5) Using a conventional controller, it has more functions than a microcomputer, such as it can store 5 sets of specifications
6) One-button operation, place the workpiece and step on the foot switch.
7) Use all-copper water-cooled transformer and temperature control to ensure that the welding machine does not generate heat
8) The pneumatic spot welding machine is 10 times faster than the foot-operated spot welding machine, saving welders labor costs of hundreds of thousands a year.
