Elevate your TIG welding precision with the CK Worldwide T187GL 1.5% Lanthanated Tungsten Electrodes. Featuring a distinct Gold color tip, these electrodes are manufactured to the AWS classification EWLa-1.5 (WL15). This composition includes 1.3% to 1.7% Lanthanum Oxide dispersed evenly throughout the tungsten matrix. This unique blend provides distinct advantages over pure tungsten and offers a direct, non-radioactive replacement for 2% Thoriated electrodes. This package contains ten 1/8-inch (3.2mm) diameter electrodes, standard 7-inch length, ready to deliver consistent arcs for your most critical projects.
One of the standout features of the 1.5% Lanthanated tungsten is its incredible arc stability and low burn-off rate. The lanthanum oxide lowers the work function of the tungsten, allowing it to start easily and maintain a stable arc even at lower amperages. This makes it perfect for delicate work on thin gauge materials as well as robust structural welding. The electrode resists thermal shock and tip degradation, meaning you spend more time welding and less time at the grinder. The "no spitting" characteristic ensures that your weld pool remains uncontaminated, which is vital when working with sensitive alloys.
The T187GL is a workhorse for DCEN (Direct Current Electrode Negative) welding. It is highly recommended for welding non-corroding steels, such as 304 and 316 stainless steel, as well as exotic metals like titanium and nickel-based superalloys. While primarily optimized for DC, lanthanated tungsten can also hold up well in AC applications with square wave power sources, making it a versatile addition to any welder's toolkit. Its ability to maintain a sharp point longer than pure tungsten makes it superior for precision DC work.
Safety is a paramount concern in modern welding shops. Because the T187GL is non-radioactive, it eliminates the health risks associated with the radioactive dust generated during the grinding of thoriated tungsten. This makes it an environmentally friendly and safer choice for welders without compromising on the high-performance characteristics needed for industrial fabrication. Trust CK Worldwide's reputation for quality consumables to keep your production line moving smoothly with these premium gold-tip electrodes.
