Tillsatsmaterial

Very easily welded omni-current electrode. Excellent thin plate electrode and the good flowability mean that both butt and fillet welds have an even and beautiful string appearance. Lightly ignites even with small transformers with 50 V open-circuit voltage (OCV). OK 43.32 is recommended for ordinary carbon steel, as well as for ship steel of A quality in ordinary strength class.

Extra low-carbon stainless steel electrode of type 18Cr 12Ni 2.8Mo intended for position welding mainly of thin-walled pipes. The electrode has a thin casing and can be welded according to the so-called ''drop welding method'' or vertical falling, which is faster. This requires an electrode with very good ignition and re-ignition properties, which makes OK 63.20 very suitable. The electrode is directly adapted for the stainless steels of types 316 and 316L, for example X3CrNiMo17-13-3 (SS2343), X2CrNiMo18-14-3 (SS2353) or corresponding steel according to other standards. The weld metal's low carbon content provides good resistance to intercrystalline corrosion but also to pitting and most types of corrosion in reducing and neutral solutions. OK 63.20 can also be used for welding stabilized steels if these are not to be operated at temperatures above 400°C. /B>

Overalloyed stainless electrode for welding stainless to other types of steel. However, OK 92.26 should be used for welding stainless against heat-resistant steels, for example SS 2116, SS 2218 (10CrMo9-10) at high operating temperatures. The electrode is suitable for bottom strings in the transition between the unalloyed and stainless layers of compound plates. OK 67.70 has excellent welding properties on both direct and alternating current. It can be used in all positions except vertically downwards and in all existing joint types. For horizontal welding in thicker materials, the fast-welding high-yield electrode OK 67.71 can be a good alternative to OK 67.70.

Highly alloyed electrode for butt welding of hard-to-weld dissimilar steels, welding of sliding surfaces, and as a buffer layer when welding hard welds. Distinctive for the welding material is high strength, high crack resistance and high wear resistance. The electrode withstands dilution and upalloying, produces high-strength welds both in high-alloyed and low-alloyed steels and when welding white dissimilar steels together. The high chromium content provides a low coefficient of friction and scaling resistance up to 1150oC. Welding at an elevated working temperature can in many cases be eliminated, except for steel with a high carbon equivalent, when a preheating around 150-200°C should be applied. OK 68.81 justifies the name universal electrode for difficult welding situations in both common and difficult-to-weld unusual steels. Suitable applications are rollers, forging tools, hot forming tools, punching pads for plastics, etc.

Overalloyed extra low-carbon stainless steel wire electrode for gas metal arc welding of austenitic stainless steels (eg 316L and 308L) against ordinary unalloyed and low-alloyed steels. OK Autrod 309LSi is recommended for example for AISI 304, 404L and X5CrNi18-10 (SS2332, W. no.1.4301) and SS2333 or equivalent stainless steels according to other standards. It is also suitable for bottom strings in the transition between the stainless layer of the compound plate and the unalloyed one. The high silicon content results in good welding properties. For material thicknesses below 3 mm, short arc welding is easier to handle than spray arc welding. Bottom strands in chamfered joints are also most easily performed with short arc welding, while the remaining strands, at least in the case of horizontal welding, can be performed faster with spray arc welding.

Silicon alloyed aluminum wire of type AlSi5 for TIG welding of AlMgSi and AlSi alloys with silicon contents up to 7%. The wire is recommended for e.g. EN-AW-6063 (SS4104), EN-AW-6082 (SS4212), EN-AW-42000 (SS4244), EN-AW-42100 (SS4245) and corresponding Al alloys according to other standards. The welding material has a high safety against cracks. Color matching between weld metal and base material during anodizing is less good. As with all aluminum welding, a high degree of discipline applies regarding cleanliness and minimization of oxide layers on joint surfaces and additive materials.

Magnesium alloyed aluminum wire for TIG welding of salt water resistant Al-Mg alloys containing up to 5% Mg. The welding wire is the most used type and intended for welding alloys corresponding to, for example, ENAW-5083 (SS 4140) where high strength of the weld joint is desired. Base material in the 5XXX series which together with OK Tigrod 5356 gives a weld metal with more than 3% Mg has good resistance to cracks caused by stress corrosion even where the operating temperature exceeds 65ºC. The alloy cannot be heat treated.

Strongest unalloyed all-current electrode especially suitable for high-strength low-alloy steels or steel castings. The electrode's resistance to brittle fracture at low temperatures is extremely good, as is the weld metal's resistance to hot cracking. It produces a weld metal with very good mechanical properties, especially in terms of impact strength. , open-circuit voltage (OCV) 65 V
