K-TIG will weld in a single, high-speed, full penetration pass on up to 16mm in titanium and other exotic materials, 13mm in stainless steel and 9mm in carbon steel. Gas tungsten arc welding, a joining process developed decades ago, has been improved by many technology developments over the years, but the essentials are unchanged: The weld symbol depicts a single bevel v groove weld that is full penetration. All times are GMT Not at this time; I'm just learning, and was simply assuming this was something I would need to be able to do if asked. It uses an arc between a nonconsumable tungsten electrode and the workpiece to produce a weld pool, and it needs a shielding gas to protect the molten weld pool from contamination by oxygen in the ambient air.
Rather, it allows a smaller fillet weld to be made with the same strength level as a larger fillet weld made with less weld penetration. The effect of arc voltage on the bead shape can clearly be seen in Figure 8. If you have shallow penetration, the weld is weaker. This is important because most applications of GTAW are manual or semiautomatic, requiring that an operator hold the torch. Keyhole TIG Limited K-TIG is an Australian unlisted public company which has developed a high-speed, single pass, full penetration welding technology that eliminates the need for wire, edge bevelling or skilled operators and produces exceptional quality welds up to x faster than conventional welding in materials up to 16mm in thickness. The slurry is applied manually using a fine-bristle brush.

To keep the article fairly short, the discussion will be limited to arc welding, two common types of weld joints T and butt and two common types of welds fillet and groove. This misconception likely occurs because they see the weld bead widen out with more voltage and become narrow and ropey with less voltage as illustrated in Figure 8. Increasing the mill line speed by an amount similar to the increased weld speed achieved for other applications would have significant ramifications, including reducing the welding cost by up to 50 percent. The product has been approved for naval, commercial shipping, aerospace, and energy applications, such as:.
Improving GTAW for producers, fabricators
Description: Introducing helium allows for greater penetration in thicker workpieces, but can make arc starting difficult. A constant-current welding power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma. Gas tungsten arc welding GTAW , a joining process developed decades ago, has found an important niche among tube and pipe producers and fabricators. It uses an electric arc between a nonconsumable tungsten electrode and the workpiece to produce a weld pool, and it uses a shielding gas. While the process doesn't produce smoke, the brightness of the arc in GTAW can break down surrounding air to form ozone and nitric oxides.
