SAW Wire Sizes and Coils

Submerged arc welding wire is one of the welding materials. It is often used in carbon steel welding. Submerged arc welding is a special welding method. Its welding quality is high and stable, and it is generally used in workpieces with high welding requirements.

Product advantages

Submerged arc welding wire has excellent weldability and mechanical properties, stable arc, easy slag removal, good weld shape and high deposition efficiency.

H08A submerged arc welding wire

H08A is carbon steel submerged arc welding wire. Combined with flux (such as SJ301, HJ431, etc.), used for welding low carbon steel, such as Q235, 20# and other steel structures. Carbon steel (such as Q195, Q215, etc.) is widely used in welding boilers, ships, pressure vessels and pipelines and other industries.

H08MnA submerged arc welding wire

H08MnA is an important low-carbon steel weldment, ordinary carbon steel with a welding strength level of 300-350MPa, high-quality carbon steel and low-alloy structural steel for welding.

If the strength requirement of the weld is low, H08A submerged arc welding wire can be used, and when the strength requirement of the weld seam is high, H08MnA submerged arc welding wire can be used. High weld strength is required, and high matching can be used, while the Mn content of H08MnA is greater than that of H08A, and relatively speaking, high matching of welds can be achieved.

Precautions :

1. The welding input energy will directly affect the mechanical properties of the weld metal. Before use, process evaluation should be carried out according to its own welding conditions, and appropriate process specifications should be formulated.

2 Before welding, the rust, oil, moisture and other impurities on the welding surface should be removed, and the welding wire should also be clean before use, free of oil, rust and water.

3. The flux needs to be baked for 1-2 hours before use (the baking temperature of sintering flux is 300-350℃, and the baking temperature of smelting flux is 200-250℃).
4. Attention should be paid to the ambient temperature and humidity for storage and storage. The indoor temperature should be above 5°C, the relative humidity should not exceed 60%, and there must be a certain distance (≥300mm) from the ground and walls; indoor classification should be stored with clear signs.

The commonly used varieties of submerged arc welding wire in China are: H08A, H08MnA, H10Mn2, H10MnSi

SAW Wire Sizes and Coils FAQ

What diameters does SAW wire come in?

2.0mm, 2.5mm, 3.0mm and 4.0mm are standard. Small diameters suit thinner plate and lower current, while 4.0mm carries the high currents used for single pass penetration on thick sections.

What coil weights are supplied?

25kg, 50kg and 100kg coils, with the larger sizes on a heavier former. Coils are wrapped against moisture and palletised for container shipment.

Which current type does SAW use?

Usually direct current electrode positive for deep penetration, or alternating current where arc blow on long seams becomes a problem. Multi wire systems combine both to raise deposition further.

What is arc blow and how is it controlled?

Magnetic deflection of the arc, most noticeable at the ends of long seams or near heavy tack welds. It is controlled by changing the work lead position, switching to AC, or reducing current and travel speed.

Can SAW be used in position?

No. The flux blanket has to stay in place, so SAW is limited to flat and horizontal work, usually with the workpiece rotated or positioned so the seam lies flat.

1. 25kg, 50kg, 150kg, 200kg, 350kg, 500kg, 1000kg all available, transverse wind without core, Vaccum packing
