Welding Filler Bands
01
Description
JSC POLEMA produces the following welding filler bands for arc-welded mechanized surfacing of wear-resistant coatings:
--PL-Np – 500Cr40Ni40Si2MnBZr-B-S (PL-AN 111);
--PL-Np – 450Cr20Nb7Mo7W2V-B-U (PL-AN 179-1);
--PL-Np–450Cr31Mo-B-U (PL-AN 180).
The bands feature a single-lock construction and consist of a steel shell and a filler powder that provides a specific chemical composition for the welded metal.
Dimensions of band cross-section: width – 16.5 ± 1, thickness – 3.8 ± 0,4.
The bands are made in rolls, wound onto a cassette. Each roll consists of a single piece of band with average weight of 45 to 175 kg. The inner diameter of a roll is 440-480 mm, and the width is 120-160 mm. If required by the customer, bands can be delivered with weight of 25kg min.

specifications
Welding filler band PL-Np – 300Cr25Si4Ni2Mn2-B-U (PL-AN 101)
The hardness of the welded metal in the second layer is 50 - 56 HRC. Wear-resistant coatings are mechanically welded with an open arc or under a flux layer. It is a universal band for restoring and protecting steel parts of metallurgical, mining, agricultural, road-building, and other equipment and machine parts against abrasive and gas-abrasive wear under moderate impact loads, normal and elevated temperatures: parts of blast furnace charging devices, rollers of coke crushers, beater bars, lining of cone crushers, conveyor grates, skip plates, bulldozer blades, screw pump sleeves, etc. The relative consumption of the band does not exceed 1.15 kg per 1 kg of welded metal.
Welding filler band PL-Np – 500Cr40Ni40Si2MnBZr-B-S (PL-AN 111)
The type of the welded metal is Ni-Cr3C2 alloy. The hardness of the welded metal in the second layer is 45 HRC min (48-55 HRC – reference data). It is used for mechanized welding of wear-resistant coatings with an open arc and under AN-20, AN-15M fluxes. It is used to protect the surface of machine parts and equipment against intensive abrasive and gas-abrasive wear at normal and elevated temperatures, for example, the contact and intermediate belts of cones and bowls of blast furnace charging devices operating in forced modes. The relative consumption of the band does not exceed 1.2 kg per 1 kg of welded metal.
Welding filler band PL-Np – 450Cr20Nb7Mo7W2V-B-U (PL-AN 179-1)
The band belongs to universal welding materials, it contains fluxing components. The hardness of the welded metal in the second layer is 60 HRC min. It is used for mechanized welding with an open arc and under flux of wear-resistant coatings with increased hardness, resistant against abrasive and gas-abrasive wear at normal and elevated temperatures. The relative consumption of the band does not exceed 1.2 kg per 1 kg of the welded metal.
Welding filler band PL-Np–450Cr31Mo-B-U (PL-AN 180)
If agreed with the customer, the chemical composition of the welded metal may be modified. The hardness of the welded metal in the second layer is 58 HRC min. Wear-resistant coatings with increased hardness are mechanically welded with an open arc. It is used to protect the surface of machine parts and equipment against intensive abrasive and gas-abrasive wear at normal and elevated temperatures.
Inspection methods of the bands' welding and technological properties, chemical composition, and hardness of the welded metal can be sent to the customer upon their request.
