CastoMag 45706 Welding rod Ø 1.2mm

CastoMag 45706

Good corrosion resistance due to atmospheric influences, even in industrial and marine atmospheres.
Work-hardening and cold-tough weld metal. Almost identical in color to pure copper.

Technical data
EN ISO 24373: S Cu 6560 (CuSi3Mn1)
W.-No.: 2.1461
AWS A5.7: ERCuSi - A

Applications
For joint welding of copper, copper-zinc and copper-silicon alloys, e.g:
2.0220 - CuZn 5,
2.0230 - CuZn 10,
2.0240 - CuZn 15,
2.1322 - CuMg 0.4,
2.1323 - CuMg 0.7
and for build-up welding of copper and unalloyed ferrous materials.
Welding of oxygen-containing copper grades with an O2 content of more than 0.02 % is not recommended.
For welding copper forgings and copper castings as well as for the manufacture of refrigeration systems (gas separation plants).

Typical applications are:
Boilers, tanks and their linings, heat exchangers, distillation and evaporation plants from the chemical, sugar and paper industries as well as from waste water plants. Also for connecting earthing rails in electrical systems.

Processing instructions
Remove cracked and otherwise damaged material. Clean welding areas. When welding, adjust the heat to the component, its material and dimensions, preheat solid workpieces up to 600 °C. Weld with short, spray or pulsed arc, prefer pulse arc technology.

Welding positions: all, except PG (f)
Type of current: = (+)
Shielding gas: EN ISO 14175 I1 (100 % Ar) I3 (max. 95% He - rest Ar)
