Rutile coated high efficiency High-Speed Steel stick electrode
Used for repair and production of cutting tools, particularly for building-up cutting edges and working surfaces. The deposit is highly resistant to friction, compression and impact, also at elevated temperatures up to 550° C. The production of new tools by welding on non-alloy and low-alloy base metals is also possible (cladding of cutting edges).
UTP 690 has excellent welding properties, a smooth, finely rippled bead appearance due to the spray arc and very easy slag removal. The weld deposit is equivalent to a high-speed steel with increased Mo-content.
Hardness of the pure weld metal: approx. 62 HRC
Soft annealed 800 – 840° C approx. 25 HRC
Hardened 1180 – 1240° C and tempered 2 x 550° C approx. 64 – 66 HRC
Basic-coated high-nickel stick electrode for cast-iron
UTP 8 is for cold welding of grey and malleable cast iron, cast steel and for joining these base metals to steel, copper and copper alloys, especially for repair and maintenance. UTP 8 has excellent welding properties. The easily controllable flow permits spatter-free welding in all positions and with minimal amperage. The weld deposit and the transition zones are filable. No undercutting.
Basic-coated Nickel-iron stick electrode for cast-iron
Suitable for surfacing and joining of all commercial cast iron grades, such as lamellar grey cast iron and nodular cast iron, malleable cast iron and for joining these materials to steel or cast steel. This stick electrode is particularly used where a high deposition rate is needed. UTP 83 FN has an excellent melting performance and the easily controllable transfer provides a spatter-free deposit of perfect appearance. The weld deposit is easily machinable with cutting tools, tough and crack-resistant.
Universally applicable for cladding on parts of steel, cast steel and high Mn-steel, subject simultaneously to abrasion, impact and compression. Typical application fields are the earth moving and stone treatment industry, e.g. excavator teeth, bucket knives, crusher jaws and cones, mill hammers etc., but also for cutting edges on cold cutting tools.
Hardness of the pure weld deposit 56 –58 HRC
After soft–annealing 780 –820° C / oven approx. 25 HRC
After hardening 1000 –1050° C / oil approx. 60 HRC
1 layer on high Mn-steel approx. 22 HRC
2 layers on high Mn-steel approx. 40 HRC
UTP DUR 600 has excellent welding properties due to a quiet arc, an even flow and a good weld build-up, easy slag removal. Machining of the weld metal possible by grinding.
Copper based alloy for TIG welding copper-nickel alloys, copper-aluminum alloys and cast iron.
UTP A 387 is used for copper nickel alloys with up to 30 % nickel according to DIN 17664, such as CuNi20Fe (2.0878), CuNi30Fe (2.0882). Chemical industry, seawater desalination plants, ship building, offshore technique. The weld metal of UTP A 387 is resistant to seawater and cavitation.
Suitable for joining and surfacing of steels of difficult weldability, repair of hot and cold working steels, cushioning layers and dissimilar metals. The weld metal of UTP A 651 is scale resistant up to 1150° C. Crack and wear resistant, stainless and work hardening. Hardness of the pure weld metal: approx. 240 HB
Primarily designed for welding 22Cr duplex stainless steels used in offshore, shipyards, chemical tankers, chemical/petrochemical, pulp & paper, etc. Avesta 2205 is an all-position electrode of E2209-17 type. The weld metal has very good resistance to pitting and stress corrosion cracking in chloride containing environments. PREN >35.Duplex alloys have good weldability, but the welding procedure should be adapted to the base material considering fluidity, joint design, heat input, etc
Spec: AWS: A5.4 E2209-17
Electrode Diameter: 2.5mm, 3.2mm
Approvals: TÜV (07139.), DB (30.014.20), Certified by CWB to CSA W48, CE
Rutile electrode, core wire alloyed for analogous, heat resisting rolled steels e.g. in annealing shops, hardening shops, steam boiler construction, the crude oil industry and the ceramics industry. In weld joints exposed to sulphurous gases the final layer has to be deposited by means of FOX FA. Smooth beads and easy slag removal. Scaling resistance up to +1200 °C. The temperature range between +650 and +900 °C should be avoided owing to the risk of embrittlement. Thick-walled welds to be carried out by means of the basic electrode FOX FFB
Rutile stick electrode high-alloyed, chemical resistant.
Avesta 309L is a high-alloy low carbon electrode designed for welding dissimilar joints between stainless and mild or low-alloy steels.The electrode is well suited as a buffer layer when overlay welding on mild steels, providing an 18Cr 8 Ni deposit from the first layer.Avesta 309L can also be used for welding some high temperature steels, such as 1.4833/ASTM309S.
Corrosion resistance:Superior to 308L. When used for overlay welding on mild steel a corrosion resistance equivalent tothat of 1.4301/ASTM 304 is obtained already in the first layer.
Avesta 316L/SKR is a low carbon core wire alloyed Cr-Ni-Mo electrode for welding of 1.4436/ASTM 316 type stainless steels.
The core wire alloyed concept ensures constant corrosion properties.
Excellent resistance to general, pitting and intergranular corrosion in chloride containing environments. Intended for severe conditions, e.g. in dilute hot acids.
Seamless rutile flux cored wire for single or multi-layer welding of Carbon, Carbon-Manganese steels and similar types of steels including fine grain steels with pure CO2 shielding gas.
Main features: excellent weldability in all positions especially vertical upward position, also with high parameters (300 A), very low spatter losses, fast freezing, easy to remove slag and smooth and bright bead. This wire is especially suitable for ship building where excellent performance and
