What electrodes are needed for stainless steel welding: types and brands

Anyone who has had to periodically weld stainless steel workpieces probably knows about TsL-11 electrodes. They are in demand not only for working with stainless steel, but also with all other metals that are resistant to corrosion. Having good technical performance, these electrodes are widely used by both amateurs and professionals. They have found their application in garages and large production facilities. When used correctly, TsL-11 electrodes form a durable, moisture-resistant seam.

MR electrodes

The most prominent representatives of the products of this oldest plant are Losinoostrovsky MP-3 electrodes. Their main purpose is welding critical structures made of carbon steels, as well as low-alloy ones. It is possible to weld parts of large thickness.

The electrodes have a rutile coating. It is possible to use direct and alternating current. Welding can be carried out in various positions in space, excluding downward movement. Cross sections of consumables: 2.5; 3.0; 4.0; 5.0; 6.0 millimeters. The number of elements of 3.0 millimeters in one kilogram is 39, and 4.0 millimeters - 16. The plant offers for purchase packs containing consumable elements weighing 1.0; 2.5; 5.0 kilograms.

Losinoostrovsky electrodes of this brand may vary in color, depending on their coating. There are blue electrodes, green electrodes, red electrodes and regular gray electrodes.

Advantages and disadvantages

The advantages and disadvantages of TsL brand consumables are largely related to their main coating.

Positive characteristics:

• the possibility of crack formation is minimized;
• due to the reduction of oxygen and hydrogen in the welding zone, the electrode metal is evenly mixed with the base metal, forming a weld with plastic properties;
• the low ability of the base coating to oxidize allows alloying during the welding process;
• lower toxicity of the base coating compared to the acidic one.

Electrodes TsL 9

List of disadvantages:

• the need to keep a short arc when welding, a long one has low combustion stability;
• short arc welding creates problems for beginners; TsL brand electrodes are more used by professional welders;
• the humidity of the coating creates conditions for unstable arc operation and leads to sticking of the electrodes;
• To obtain a high-quality seam, it is necessary to remove scale and other contaminants, and then degrease the welding edges.

Electrodes 29/9

LEZ-29/9 electrodes are intended for joining difficult-to-weld steels. Not only identical, but also dissimilar steels can be welded together. In this case, the manual arc method is used. AC and DC current can be used. Consumables cross-section size: 2.5; 3.0; 4.0 millimeters.

Where to buy LEZ electrodes

SSSI consumables

LEZ welding electrodes include such widely popular consumables as UONI-13/55. It is possible to connect with each other critical products that will be operated at low temperatures. When using UONI-13/55, it is possible to obtain a plastic seam with sufficient impact strength. The durability and toughness of the seam is ensured by a wire rod made of low-carbon steel.

The main advantage of this type of electrodes is that the seam when working with them is resistant to cracking. It also contains a reduced amount of hydrogen. The recommended technology when using them is a short arc. Lengthening the arc will negatively affect the quality of the seam.

The coating UONI-13/55 does not contain organic inclusions, so they can be calcined at high temperatures, ensuring immunity to moisture.

Manufacturers and brands: LEZ, Monolit and others

The domestic market for CL brand consumables is represented by both Russian and foreign companies . Moreover, among foreign manufacturers, manufacturers from Belarus and Ukraine prevail . To a lesser extent, market demands are met by higher quality, but at the same time more expensive, products of European brands (Swedish ESAB, German ZELLER and others).

Electrodes of the TsL LEZ series in packaging

Among the Russian manufacturers producing TsL brand electrodes, the following stand out:

• “LEZ Trading House” is an enterprise operating in the welding materials market for more than half a century, its products have certificates from independent expert organizations;
• "Electrod" in Tolyatti is a young developing enterprise, already occupying a leading position among Russian ones. St. Petersburg is a joint Swedish-Russian enterprise with production technology using modern high-quality equipment;
• Sudislavsky Welding Materials Plant, Kostroma Region, firmly holds first place in the production of electrodes in the price-quality category.

TsL brand electrodes produced in Ukraine and Belarus are not inferior in quality to the best Russian ones, but have a higher price. The consumables from the Svetlogorsk Electrode Plant of the Republic of Belarus are in greatest demand. The products have quality certificates confirmed in the CIS countries. The brands of this company are popular among Russian welders: Monolit, Continent, Arsenal.

Electrodes TsL-11

LEZ TsL-11 consumables are used for manual arc welding. They have proven themselves well in joining corrosion-resistant steels. They are operated using direct current. Welding must be done with a short arc. Coverage is basic.

The advantage of these consumables is that the seam obtained by using them is highly resistant to corrosion when used in unfavorable conditions.

Application

So, you know that maka TsL-11 is often used for welding special types of steels and critical structures. But this information is not enough to make your choice. How good are these electrodes? Is it possible to cook stainless steel?

Our answer: yes. These are real stainless steel electrodes. They are literally designed for welding stainless steels. They are also designed to work with metals that must withstand aggressive environments and high temperatures. It is when welding such metals that these electrodes reveal their full potential.

Summary

The choice: to take or not to take electrodes from LEZ depends only on you. If we take the indicators price: quality, we get a good ratio.

Here habit comes to the fore, as in the saying about taste and color. For family craftsmen or debutants in the field of welding, the purchase of these electrodes will be profitable.

I spoiled it, took another one, without straining the family budget too much or without bankrupting the employer. Do you already have an opinion on this matter? Add it to the comments! And success to all buyers of welding rods from LEZ!

Marking of electrodes on stainless steel

According to the requirements of interstate standards, all electrodes must be marked with the following information:

• Purpose of the product;
• Type of coverage;
• Polarity;
• Maximum current;
• Operating voltage.

In addition to the above information, the packaging must contain information about the manufacturer and the expiration date of the product.
