Copper belongs to metals with high electrical and thermal conductivity properties.Copper melts at 1085 degrees Celsius, and differs from other high density metals.
How is welding copper?Consider more!
copper welding is carried graphite, carbon, metal electrodes, as well as gas medium.Technology of graphite and carbon electrodes are based on the use of a tungsten electrode, which is an electric arc welding.The seam formed in this case by melting the filler material and the edges of the article.
also to carry out welding of copper coal or graphite electrodes, it is necessary to process the edges of welded parts.This can be done by means of grinding power tools.
Welding electrodes of copper produced through the use of protective fluxes.In this case, as boron acts as a flux or slag drill.Before welding, the drill is applied to the chamfer.
After the flux has dried, you can begin to weld copper.This will require additional material.Often, such a bronze or copper wire.The diameter of the additive depends on the thickness of the product.For durable weld need to perform heating chamfer.This procedure should be performed prior to the welding of copper.In addition, it is necessary Pokrovka seam and rapid cooling.Copper weld carbon and graphite electrodes, DC.
If it uses a steel electrode, while the electrode material is entirely dependent on the material to be welded.Usually it uses a variant of bronze.The source of power is a welding machine or other equipment and welding transformers.
to weld copper with protection of inert gases used melting and non-consumable electrode.To include non-consumable tungsten rods for MIG - copper and bronze electrodes.
for welding copper tungsten rod is used alternating and direct current for welding copper and bronze - a constant.The most reliable and durable welding copper welding connection is in a gaseous environment.
Argon welding as the most universal method
argon welding copper is a versatile option with many advantages.It is used in this process if:
- important exterior components, and assemblies;
- need to carefully make a hole or crack;
- restore previously broken mount.
Types of welders
welding machine - a generic term for a conditioned type of an entire group of devices for industrial use, used for arc welding by melting.Professionals often referred to as welder welding power source.The biggest demand is equipment for manual welding with stick electrode.
Welders are classified as follows:
- instruments for the implementation of the gas and resistance welding manual type;
- machines with semi-automatic and automatic control of the welding process;
- special machines for welding: welding Argon installation.
should also be noted that today in great demand among the population are welders household type.
