CLASSIFICATION: E46 in accordance with GOST 9467-75

CONTINGENCIES OBOZNAENIYA: E46 - ANO-4 - Ø - UD
                                                                 E 430 - P24

TECHNICAL REQUIREMENTS: GOST 9466-75 and TU BY 100034500.041-2012

COATING: rutile

PURPOSE:

Intended for welding of structures made of carbon steel with carbon content up to 0.25% and a strength up to 490 MPa. Admit wet welding, rusty, poorly cleaned from oxides and other metal contaminants. The electrodes are light arc ignited.

In all spatial positions of the weld, except vertical "top-down", alternating current and direct current reverse polarity.

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)	1,4-1,6 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

Chemical composition of deposited metal:

Element content, weight%
Carbon	Manganese	Silicon	Sulfur	Phosphorus
No more	0,35-0,70	No more
0.12		0.20	0,040	0,045

DIRECTIONS FOR USE:

In case of exceeding the permissible moisture content in the coating (1.5%) before use further electrodes are calcined at a temperature of 140-160 ° C for 40-60 minutes.
WELDING MODES:

Electrode diameter mm	Welding current, A
	joint position
	Underwear	vertical	ceiling
2.5	60-90	50-80	50-80
3.0	80-100	60-100	60-90
4.0	120-150	110-140	110-140
5.0	180-220	170-200	-

Welding is made on the average length of the arc from the electrode to tilt toward the direction of welding (back angle).
