The színréz and fusion, mid die process easy to weld. Welding Consideration should be given to:

- The strength of small, high elongation, high thermal conductivity due to higher welding heat input, preheating is required,

- The copper oxide-containing hydrogen was added when called. Hydrogen disease occurs

- Copper oxide (Cu ₂ O) forms a eutektikumot and down, the lower melting point eutectic kiválva the grain boundaries reduces the toughness.

The welding of copper should not gázhegesztéssel gázlánggal be made ​​because the copper oxidizes rapidly when hot neutral flame during welding, the reducing flame of hydrogen leads to the weld, and it leads elridegedéséhez.

The thermal performance of small welding flame welding of copper, it is always necessary to heat-mate. It is necessary to dissolve the oxides of flux applied, which is corrosion damage, inclusions could be caused by bare metal before welding of the workpiece. The színréz neutral gas welding flame, balrahegesztéssel, using the flux should be performed.

The proposed phosphorus-containing consumables, CuAg alloy silver alloy. A 6 mm thick plate of at least 200 l / mm hx specific flame intensity to be heated.

The rézömledék dense liquid due to the weld surface is very uneven pikkelyezett so hidegkalapálással the strength, toughness melegkalapálással be improved. The hammering action of 80-mm sections with frayed seams.

Arc welding of copper and védőgázo TIG welding of a copper thickness of 5-6 mm can be recommended. Welding with DC straight polarity volfrámelektródával thorium alloy is carried out. The gázlánghegesztésnél used welding rods and wires for TIG welding színréz not be used because of the weld porosity.

6 mm and more preferable to AFI welding, where over 12 mm preheating is necessary 300-400 ° C, and multi-layer welding at 500-700 ° C.
