Welding of non-ferrous metals - it does not spoil the expensive communication?

Non-ferrous metals and welding

physical properties and purpose of nonferrous metal are divided into:

  • lightweight (magnesium, aluminum, titanium);
  • heavy (tin, nickel, lead);
  • precious (gold, silver, platinum);
  • scattered;
  • refractory;
  • rare;
  • radioactive.

flame treatment of non-ferrous metals - is the processes that are associated with exposure to high-temperature gas flame on the product.In other words, the cutting and welding.Often there is a need for welding products in the household.

gas welding of non-ferrous metals has its own characteristics, which should be considered.For example, copper is strongly oxidized, the resulting oxide reduces the strength and quality of the weld.When working with copper to the mandatory use of fluxes, which convert oxides formed in the low-melting slag.

The industry is a completely different technology welding ferrous metals - microplasma welding.This technique is used for welding sheet metal thickness of less than 1 mm.It is used in many industries, and over the next decade, an alternative to this technology is unlikely to be invented.

Electrodes for welding ferrous metals have many varieties.For example, electrodes for welding of aluminum and its alloys, welding technical purity aluminum bronze welding and heat-resistant alloys for welding and surfacing copper, nickel alloys, and many others.

cutting non-ferrous metals - quickly and qualitatively?

cutting nonferrous metals conducted several major ways, depending on the metal type and quality of cut.The first class of accuracy are mechanical, laser, waterjet cutting, the second - gas and plasma cutting.Ideal cutting edge and high precision can provide mechanical cutting methods: milling, drilling, chamfering, grinding, turning, and others.

But the most advanced method is laser-ferrous metal cutting.Under the action of the laser beam energy at the surface of the sheet opening is formed, and the molten metal is blown a high pressure gas mixture.This method of cutting different strain and lack of opportunity to create a profile of high complexity.

Such a method can be used to hire no more than 20 mm thick.If the customer importantly - save money, and it does not impose high requirements for precision and tolerances of parts manufacturing, the ideal - gas cutting.

soldering non-ferrous metals - create high-quality seams

Another important process - it brazing ferrous metals .Creating a permanent connection is produced by heating a low-melting metal (solder) to its melting, and it fills the gap between the connected elements.Types

soldering differ depending on how the heating method was carried out: a gas, brazing immersion in salt bath, electrical, ultrasound.Information much, but clearly this confusion will help to streamline the proposed video, non-ferrous metals then cease to be something distant and incomprehensible.

In the treatment of such material, whether it be welding, cutting, welding or soldering, you should always observe the safety rules.Measures should be taken to avoid burns, electric shock, explosions and leaks gas mixtures ejection of molten metals and salts, harmful radiation action.
