For now when performing welding work using copper-free and copper-coated welding wire increases. 

Welding wire Sv-08GA, GOST 2246-70.
This is the best welding wire for automatic submerged arc welding of carbon steels with a yield strength of 235-440 MPa (bridge structures, towers, chimneys, pipes and boilers operating at high pressures and temperatures).
Sv08GA is used for welding low alloy and low carbon steels, carbon steels 10 HSND in the gas mixture (Ar-80% + CO2-20%), in pure CO.
This welding wire is used for welding welded pipes and welding in power engineering. Sv08GA used in the production of gas and oil pipes with large diameter alloy steels designed for high operating pressure at low temperature. Welding wire Sv-08GA is approved by Russian Maritime Register of Shipping in combination with flux AN-42 and AN-47. Welding electrodes are produced this wire.
Welding is performed at a constant current.
Externally welding wire Sv08GA has little difference other types of welding wire it is supplied in coils, crocked into the plastic film.
If you decide to buy welding wire SA08GA on cassettes, it will be metal cassettes of 15 kg, packed in plastic film and stacked in cardboard boxes.
You can buy us welding wire Sv-08GA with a diameter of 0.8 to 6 mm, copper covered and without coppering and polished. Most often wire welding Sv08GA diameters of 2 mm or more is bought.
We recommend You to pay attention to the polished welding wire Sv-08GA. We can give you a sample of the of wire for you to check its quality.
You can buy the welding wire Sv08GA also in coils..

Welding wire Sv-08HM
Low alloy chrome molybdenum copperplated welding wire, which is used for semi-automatic welding of type HM and low alloyed steels in the gas mixture (Ar-80% + CO2-20%), for automatic submerged arc welding of oil and gas pipes and metal structures of responsible use of carbon and low alloy steels with tensile strength 235-440 MPa (bridge structures, towers, chimneys, pipes and boilers operating at high pressures and temperatures). It is often used with welding flux AN-348. Welding works using Sv-08HM are carried out using DC reverse polarity.
You can buy welding wire Sv-08HM copper covered and without coppering in coils and on cassettes. This is one of the most universal welding wires, with a help of which you can weld both low carbon steel and other high-tech steel.

Welding wire Sv-10NMA
Automatic submerged arc welding low alloy steels of high strength and cold resistance level of metal structures with responsible use (bridge structures, towers, boilers, pipes and pipelines operating at high pressures and temperatures).

Welding wire is produced according to GOST 2246-70 and TU U 322-4-392-96, TU 14-15-373-95, DSTU 3671-97.
There are grades with copper-free surface for steel with low carbon content and the wire with copper-plated surface for constructions of low-alloy and carbon steel.
Copper-plated surface of the welding wire is designed to maximize the quality of the weld and connections that can withstand relatively high temperature and shock load, resist tearing.
This welding wire is used for structural steel and shipbuilding, large diameter pipes, and also for vessels and tanks under high unit pressure.
The diameter of the welding wire with copper-free surface is 0,8-6 mm and with copper-plated surface is 0.8-1.6 mm.

Marking of welding wires

Identification of marks of welding wire is composed of a combination of letters and numbers.
The first two letters "Sv" mean that this is welding wire.
Next to them two digits indicate the carbon content in hundredths of a percent.
Then the next letter designations of elements contained in composition of welding wire. If the content of alloying elements in the wire is up to 1 per cent there is put only the letter of the item, and if the content of alloying elements is greater than 1 percent, registered after the letter indicates the percentage content of this element in whole units.

Basic requirements for the welding wire:

The chemical composition of the welding wire must match the composition of metal, of which welding parts or elements are made, welding wire must melt at a temperature substantially equal to the temperature of the metal melt to be uniform, and the welding wire itself should not be dirty or oxidized.

 

The advantages of copper-coated welding wire over other types of wires.

· Excellent quality and tightness of the weld.
· Arc stability in a wide range of welding ( drip to spray transfer of electrode metal into the weld pool) when using welding equipment of any complexity class.
· Reduced level of metal loss for spill up to 40% when welding in shielding gases.
· Reduced porosity, improved look.
· Low consumption of copper tips (coated wire does not have an abrasive effect on the channel of the tip).
· Increasing the level of mechanization of welding.
· Re-ignition of the arc (especially for robotic welding).
The use of copper-coated welding wire indicates its undoubted advantages over the wire with other types of coatings.
