nov 08, 2018 pure tungsten for years was the best choice for AC welding, but with the industry shift to invert based machines, with advanced squarewave technology, rare earth tungsten such as ceriated and zirconiated are an option. the most commonly used electrodes today are thoriated
tungsten vs. tungsten carbide. although often used interchangeably, there are differences between these two terms. tungsten in its pure form cannot be used in jewelry. instead, it is formed into a metal, consisting of approximately 85% tungsten and 15% carbon, nickel or cobalt which is known as tungsten
unlike thoriated tungsten, these electrodes are suitable for AC welding and, like ceriated electrodes, allow the arc to be started and maintained at lower voltages. compared with pure tungsten, the addition of 1.5 percent lanthana increases the maximum current-carrying capacity by approximately percent for a given electrode size.
sep 23, 2010 the golf ball is far denser and will fly farther and hit harder. now reduce that size down to two single no. pellets, one steel and the other a tungsten alloy. get the picture? the tungsten will fly farther, hit harder and penetrate deeper. that means more birds, farther out, with fewer cripples.
feb 07, 2021 have to make a part that has a concave half sphere of about inch diameter in tungsten. think a bowl shape. what would be the best way to do it. was thinking of using a round insert. are there better solutions. dont have surfacing in esprit otherwise would have done it with a ball mill and the axis.
interestingly, the density of tungsten is virtually the same as the density of gold, so if you want to make fake bars of gold, using tungsten in the core would be a really good idea. getting the weight right is important because gold, like tungsten, is extremely dense, nearly twice the density of lead. No one who knows
consisting of pure tungsten powder suspended in a matrix of copper these alloys are readily machinable and known molybdenum like tungsten, molybdenum is one of the refractory metals.
dec 18, 2020 re: choosing tungsten. originally posted by motolif. they actually say a long sharp point will fan out the arc more and a more blunt point will make a more narrow arc. you will find a different size ball depending on how long a taper on the tungsten and how many amps you use.
tungsten spheres. our tungsten spheres are fully sintered solids. these are spherical-shaped, ball-like solids with a parallel band around one axis of the diameter. the diameter of this band is identical to the balls diameter and is an essential part of the manufacturing process. when inquiring, please specify the
