Welding and cutting of nickel and its alloys
Welding technology
Welding structures made of nickel and nickel alloys has its own characteristics. The most widespread is argon arc welding with a tungsten electrode. Welding nickel and nickel alloys with direct current of direct polarity ensures high quality of the weld. Argon-arc welding with a fusion electrode is also used in a small volume. Welding nickel and nickel alloys requires the use of electrodes (European, domestic or international standard). The electrodes are usually made from tungsten, because refractory metals provide high reliability of welding joints due to high welding temperature.

Cutting elements
Nickel is cut with carbide inserts as a cutting element in toolmaking. Such products are divided into 2 types: solderable and replaceable. The advantage of the latter is that several different operations can be carried out sequentially on the same machine. In the production of carbide plates (BK6, BK60M, BK8, BK10) refractory metals are used:
- tungsten;
- titanium;
- cobalt;
- tantalum.
For example, soldering carbide inserts ВК6, according to GOST requirements, are made of tungsten. It makes it possible to use metal-cutting tools at high cutting speeds at temperatures up to 1000 C. Cutting of nickel can be carried out by carbide plates ВК8 Buy them easily, they are almost identical to BK6 in terms of heat resistance, but have a higher tensile strength at bending.
Another good option for use as a drill bit, cutter or milling cutter would be BK10 carbide inserts with a hardness of HRA of not less than 87.0 As for the bending strength, it is even higher than that of BK6 and BK8 and is not less than 180 kgf/mm2. Nickel alloys are cut and drilled at low speeds
Quite often metal carbides are added to tungsten alloys. This reduces the brittleness of the product and therefore increases its useful life. In addition to pure tungsten (BK6, BK8, BK10), there are also carbide plates, which add such rare metal alloys like titanium (T14K8), titanium with tantalum carbide (TT10K8B) and tungsten-free (TN20 or KHT16).
