Inverter welding is a proven way to join stainless steel products. It is recommended to everyone for welding work.
Many owners of dachas and garages cannot do without an inverter-type welding machine. But everyone is wondering if stainless steel parts can be welded. The answer is simple. If all the necessary requirements are met, then this will be done.
Inverter welding is carried out using special electrodes. For example, OZL-8. This type of electrode is convenient for welding stainless steel parts with markings:
• 08X18H10T;
• 08X18H10;
• 12X18H9.
Using special electrodes, intercrystalline corrosion can be avoided. A weld is obtained when special electrodes are used. He will be able to endure the effects of acidic and alkaline environments, and not just atmospheric phenomena.
Stainless steel is welded with an inverter using stick electrodes. They are designed for stainless steel (MMA) and gas shielded (TIG) welding.
Welding is carried out using a sourcedirect current with reverse polarity short arc. This means that the electrode must be polarized with a plus sign, and the workpiece must be with a minus sign.
TIG welding inverter is used to avoid oxidation or ozonation. Before starting work, it is necessary to thoroughly clean the entire surface of the material from contamination. The direction of the weld can be in any spatial position.
When choosing an inverter, consider the following nuances:
1. The device must operate at high and low voltage. Supply voltage deviations are allowed within 20%.
2. The temperature range is very important. Some models cannot work at low temperatures. The EN 60974-1 inverter is capable of operating in the range from -40˚C to +40˚C.
3. For domestic purposes (stainless steel or aluminum welding), 160 amperes at the output will be enough. But for professional work it is better to use devices with a power above 200 amperes.
Study your passport carefully. See if the inverter is suitable for your purposes. It indicates the type of electrodes that are suitable for this model. Do not forget that the type of welding depends on the grade of steel and its purpose.
Inverter welding has many advantages:
1. Increasing and decreasing the voltage in the network up to 20% does not play a big role.
2. Very high quality seam.
3. The consumption of electrodes is less because the level of metal spatter is very low.
4. Ability to use moreuniversal electrodes for different types of stainless steel.
If you are the owner of an inverter-type welding machine, then you can do all the work yourself. Thus, the cost of electrodes will be directly proportional to the cost of these works. The maximum price for electrodes is 700 rubles per pack, but cheaper options can be found. If you turn to a welder for help, the amount for services will at least double.
Inverter welding is not that complicated. It is within the power of everyone. The main thing is desire, and you will succeed.
