Flux cored welding wires WELDABILITY-Sif, a UK based ‘one stop’ welding product source, has introduced a range of SifCored rutile flux cored welding wires to its Sifbronze brand of welding products. The SifCored range is used with DC MIG welding machines and in most cases is suitable for welding in all positions. It is often used in shipbuilding, offshore and construction applications welding mild steel pipe, tubes, strip, forgings and a range of pressure vessel steels. Mechanical properties include UTS >570N/mm 2 and 510N/mm 2 yield strength.

>570N/mm 2 and 430N/mm 2 yield strength. E2209T1 is designed to weld with a stable, spatter free arc AISI S31803 or EN 1. 4462 Duplex stainless steels, producing excellent chloride pitting corrosion resistance welds due to the high nitrogen and molybdenum. Typical mechanical properties include UTS >670N/mm 2 and 850N/mm 2 yield strength. SifCored E309LT1-1/14 is designed to weld together dissimilar metals and can also be used to weld a first layer on mild steel or low alloy steel prior to overlaying. This wire produces a smooth weld bead surface with self-releasing slag, and typical mechanical properties include UTS >560N/mm 2 and 440N/mm 2 yield strength. Weldability-Sif supplies MIG, TIG, MMA, spot and oxy/fuel welding and plasma cutting machines, torches, accessories, consumables and personal protective equipment to the UK distribu- tor market, and also exports to a number of countries around the world. The company’s Letchworth Garden City facility enables distributors to source over 2,000 different products, and allows the company to maintain its stock of high volume consumables, including the distribution of over 4,000 tons of mild steel MIG welding wire per annum to the market.

SifCored E110C-CG produces a stable and spatter free arc and is used in offshore, pipeline, crane and construction applications where 690N/ mm 2 yield and 110ksi class high strength steels are used. E81T1-Ni1 is used to weld low temperature service steels producing an excellent weld bead, easy slag removal and negligible spatter. It is used in offshore applications, pipeline and pressure vessel construction and has typical mechanical properties of UTS >582N/mm 2 , and 517N/mm 2 yield strength. For stainless steels, SifCored E308LT1-1/4 produces a stable and spatter free arc and is used to weld 18%CR, 10%Ni stainless steels where temperatures up to 600°C and/ or solution treatments are applied. Typical mechanical properties include UTS >600N/mm 2 and 420N/mm 2 yield strength. SifCored E316LT1-1/-4 produces a stable, spatter free arc producing a smooth weld bead and self-releasing slag to weld 18%Cr, 12%Ni, 2.5%Mo 316L stainless steels. Having a low carbon content it is possible to obtain high resistance to intergranular corrosion. Typical mechanical properties include UTS

SifCored 3E70C-6M produces low hydrogen weld metal with excellent mechanical properties, when welding mild steel and 490Mpa high tensile steels. Typical mechanical properties include UTS (ultimate tensile strength) >600N/mm 2 and 510N/mm 2 yield strength. It is used for steel tank, bridge and on-site construction as well as shipbuilding. E71T-1 is used for welding of thin sheet steels and unalloyed or low alloyed structural steels using CO 2 or Argon/CO 2 shielding gases.

Digitised two-dimensional objects are generated onto the screen in a field of automatic toolpath points. Techno’s TechProbe software allows the scan to be viewed through its active-preview

TECHNO Inc has launched its latest CNC plasma accessory: the TechProbe Digitizer. The new digitising probe mounts easily to any Techno CNC plasma machine. The user-friendly TechProbe software will digitise an object with simple or complex geometric shapes. The user inputs the object, scan-area dimensions and desired step resolution
