PURPOSE:

ANO-welding electrodes 21 are intended for the welding arc, splice, lap joints of metal of 1-5 mm thickness in all positions, including vertical joints method "top-down".

CHARACTERISTICS Electrodes:

arcing	sustainable
splashing degree	small
formation of the joint	a good
Separation of the slag crust	good
The tendency of the weld metal to pore formation	low
deposition rate (in the lower position of the weld)	8.0-9.0 g / Ah
deposition rate (electrode diameter 4.0 mm)	1,2-1,6 kg / h
Electrode consumption per 1 kg of weld metal	1.7 kg.

Typical mechanical properties all weld metal (at normal temperature)

Tensile strength, MPa	Yield strength, MPa	Relative extension, %	Impact toughness J / cm2
450	360	18	78

Chemical composition of deposited metal:

Element content, weight%
Carbon	Manganese	Silicon	Sulfur	Phosphorus
No more	0,35-0,80	No more
0.12	0,35-0,80	0.35	0,030	0,035

DIRECTIONS FOR USE:

Have a low penetrating power. Allows welding on the oxidized surface.

WELDING MODES:

Electrode diameter mm	Welding current, A
	joint position
	Underwear	vertical	ceiling
2.5	60-90	50-80	50-80
3.0	90-130	80-110	80-110
4.0	140-180	120-160	120-160
5.0	170-220	150-190	-

Welding method "top-down" is performed journalled, the electrode must be in bissektrisnoy plane at an angle 40-70 ° to the direction of welding. Calcination welding electrodes ANO-21 prior to welding: 120 ° C; 1 h.
