Weldcraft Expands Tungsten Electrode Offering

Details: Category: Tungsten Information; Published on Friday, 10 May 2013 11:40; Hits: 2346

Weldcraft has expanded its premium tungsten electrode offering to include 2 percent lanthanated and zirconiated tungsten electrodes. Like its existing tungsten electrode offering – pure, 2 percent ceriated, 1.5 percent lanthanated, rare earth and 2 percent thoriated – the new additions have undergone rigorous testing to ensure the highest quality and performance.

The 2 percent lanthanated tungsten electrodes provide similar characteristics as the 1.5 percent lanthanated tungsten electrode, but with improved arc starting and stability, and less tip erosion. They are also a good substitute for 2 percent thoriated tungsten electrodes. The new zirconiated tungsten electrodes resist spitting in higher current applications, minimizing the opportunity for tungsten contamination. These electrodes also provide excellent arc starts and stability, and ball up easily in AC applications, ensuring a smooth arc.

Weldcraft offers all of its tungsten electrodes in seven-inch lengths and in five industry-standard diameters (0.040-, 1/16-, 3/32-, 1/8- and 5/32-inch). Each package of ten tungsten electrodes features three languages – English, Spanish and French – and is color-coded according to American Welding Society (AWS) A5.12 and ISO 6848 standards: pure – green; 2 percent ceriated – grey; 1.5 percent lanthanated – gold; 2 percent lanthanated – blue; rare earth – aqua; 2 percent thoriated – red; and zirconiated – brown.

Used as a defense and military weapons and precision electronics industry and other precision technology and materials in the field, the tungsten carbide rod packing needs to pay attention to the following matters:

(1) Tungsten carbide rod required PE Pearl cotton material individually wrapped, placed in a suitable wooden box;

(2) And you must fill the extra gap, in order to prevent vibration during transit.

Tungsten Carbide Rod - Industrial Use

Details: Category: Tungsten Information; Published on Friday, 10 May 2013 11:05; Hits: 2366

Tungsten carbide rod are non-ferrous metals, is also an important strategic metal, tungsten ore was known as "heavy stone" in ancient times. 1781 the Swedish chemist Carl.William found scheelite, and extracted the other new elements acid, 1783 Spanish Depp Air Asia wolframite extracted tungsten carbide acid, the same year, the tungsten powder was gotten for first time and named the element. The tungsten content in the earth's crust is 0.001%. Tungsten carbide rod is mainly Steel gray or silver-white with high hardness, high melting point, and is from the air in the room temperature erosion.

The industrial purpose of tungsten carbide rod is to create the filament and high-speed cutting steel, hard mold, also for optical instruments, chemical instrumentation.

Tungsten Carbide Rod Surface Color Classification

Details: Category: Tungsten Information; Published on Friday, 10 May 2013 11:12; Hits: 2463

There are mainly three color classification of tungsten carbide rod surface.

1. The sintered tungsten carbide rod surface is the silver gray metallic luster.

2. Forged tungsten carbide rod with a layer of oxide on the surface is black.

3. The polished tungsten carbide rod is silver gray metallic luster.

Why would I use Ceriated or Thoriated tungsten instead of Pure?

Details: Category: Tungsten Information; Published on Thursday, 09 May 2013 18:05; Hits: 2418

With the introduction of new power source technologies, the use of pure tungsten is decreasing.
Pure tungsten melts at a lower temperature causing it to easily form a rounded ball at the tip. When the ball grows too large, it interferes with your ability to see the weld puddle and causes the arc to become unstable.
Ceriated tungsten can withstand higher temperatures and works very well with the new squarewave and inverter machines for the following reasons:
Holds a point longer and starts well at low amperages.
Can be used on both AC and DC polarities. When welding aluminum, it has become very acceptable to grind a point on ceriated tungsten (especially when welding on thinner materials).
