German standard for flux-clad welding wire for non-alloy and low-alloy steel (DIN1913 PART 1 JUNE 1984).
This flux shielded welding wire standard It was compiled by the German Welding Society.
The welding wire symbol consists of the following parts:
Note: Welding is a job with a high income potential for people working in this job. Especially with people with high welding skills. You can learn about electric and gas welding. And find more welding equipment at our website : https://www.udo.co.th/product/detail/yawata-316l-16
- Category showing flux covered wires
- DIN standard
- Symbol letter E means manual arc welding.
- The symbol shows the tensile stress, yield stress and elongation.
- The symbol shows the shock resistance test value.
- The symbol indicates the type of cladding flux.
- Symbol showing the layer of welding wire.
- Numerical value shows the efficiency of the welding wire
the meaning of the symbol
Class 7 welding wire (7) , Flux clad electrode (E) , tensile strength of weld metal 430-550 N/mm² , term stress not less than 355 N/mm², minimum elongation 22 % (43) , minimum impact strength 28 Joules at -20ºC and minimum 47 μC at 0ºC (32) , Acid-rutile (AR) thick flux
the meaning of the symbol
Class 11 welding wire (11) , Flux covered electrode (E) , Tensile strength of weld metal 10-650 N/mmº, yield stress not less than 380 N/mmº, minimum elongation 2296. (51), value
Impact resistance minimum 28 L at -20 C and minimum 47 Joules at 0’C (32) thick sheathed flux, rutile (RR) type and wire performance between 155 and 165 (160).
Flux-clad typeface symbols
Flux cladding is divided into 3 thickness levels.
– thin sheathed flux is a total thickness of 120%.
– Medium thick cladding flux is the total thickness of 120 -155 %
– Thick flux is the total thickness of 155%
A = Acid clad flux
R = Rutile type cladding flux (thin or medium thick cover)
RR = Rutile type cladding flux (thick cladding)
AR = Acid-rutile cladding flux (mixed type)
C = Cellulose type cladding flux
R(C) = Rutile-cellulose cladding flux (medium thickness cover)
RR(C) = Rutile-cellulose type cladding flux (thick cladding)
B = Alkali type cladding flux
B(R) = Alkali-type cladding flux, non-alkali component
RR(B) = Different type of cladding flux-rutile (thick cladding)
welding wire standard alloyed and non-alloyed steel For shielded gas welding processes (DIN 8559 Part 1 July 1984)
This standard applies to Wire Electrodes, Filler Wires, Solid Rode and Solid welding rods for Covered Gas (SG) welding processes capable of welding alloyed and non-alloyed steels. These are steels with a minimum stress of 500 N/mmº, excluding chromium and molybdenum alloy steels.
- Type of welding wire
Welding rods for gas shielded welding processes which can be divided as follows: Solid Wire Electrodes, Solid Wires, Solid Rods and Flux Core Wire Electrodes.
1.1 Solid Wire Electrodes, Solid Wires and Solid Rods
Classification of such wires according to the chemical composition of the wire
1.2 Flux Cored Wire Electrodes
Classification of welding wires according to the chemical composition of the weld.
- Welding wire symbol
The welding wire symbol consists of the following parts:
- a) the name of the welding wire
- b) DIN number
- c) the chemical composition of the welding wire
1.1 Chemical Ingredient Code
- Chemical Composition Code of Solid Wire Electrodes , Solid Wires , Solid Rods
- Chemical composition code of welds obtained from Flux Cored Wire Electrodes.
The letters indicate the main elemental ingredients of the flux filament as follows:
R = rutile
B = alkaline
1.2 Examples of welding wire symbols
Solid Wire Electrodes Type SG 2 For Covered Gas Welding It can be written as follows: Wire Electrode DIN 8559-SG2
Solid Rod Type SG1 for TIG welding (WSG 1) can be written as follows: Solid Rod DIN 8559-WSG1
- Symbol of the weld
The symbol consists of the following parts:
- a) Code indicating the composition of the welding wire. and weld
- b) Cover Gas Show Code
- c) The code showing the tensile stress
- d) Impact test energy numeric code
3.1 Code for stress and elongation
The symbol depends on the yield stress of the weld.
3.2 Impact test energy number code
The number code shows the minimum energy of the weld only. It consists of two code numbers: First Digit, indicating energy 28 J, and Second Digit, indicating energy 47J.
weld symbol example
Weld body obtained from type SG2 welding rod using M2 gas, minimum yield stress 460 N/mm² (Y 46) and minimum impact energy 28J at -40 ºC (5) and 47J at -30 ºC (4). Written as follows: Weld Metal DIN 8559-WSG2-IY4654
