\"\"<\/a><\/p>\n

There are quite a few changes happening in the tungsten electrode<\/a> market this year.\u00a0 One of the notable changes comes from Weldcraft<\/a>, one of the most trusted brands in TIG \/ GTAW.\u00a0 They have just rolled out a more robust, and completely re-styled line of tungsten electrodes.<\/p>\n

While there is no change in quality or composition of their premium brand tungsten electrodes, they have made some significant changes to the product offering, with the additions of Zirconiated<\/a> tungsten and 2% Lanthanated<\/a> tungsten.\u00a0 Also, a couple changes to the color code designations now align Weldcraft’s line of electrodes seamlessly with the AWS and ISO standards.<\/p>\n

These color changes are a welcome standardization in a market that has, over the years been a bit uneven.\u00a0 Previously AWS and ISO tungsten electrode color codes were different on certain materials, like Ceriated<\/a>, Rare Earth<\/a>, and Zirconiated.\u00a0 This has lead to some confusion in the marketplace, with different manufacturers having to choose which designation to follow.\u00a0 But in recent years, the AWS has reclassified the color codes to match the ISO.\u00a0 Weldcraft’s adoption of these new designations will further unify the tungsten electrode designations.\u00a0 The new designations are as follows:<\/p>\n

AWS Class\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Color\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Alloying Element<\/strong><\/p>\n

With Sylvania’s tungsten electrode brand disappearing, Weldcraft’s product line expansions are a welcome addition to the premium electrode market.<\/p>\n

Note: While the Sky Blue designation for Rare Earth tungsten electrodes has not been adopted by the AWS, it is consistent with several European and American manufacturers\u2019 color code\u2014including ArcTime Hybrid Performance<\/a> tungsten electrodes.<\/p>\n
