3 Classification
The classification includes all-weld metal properties obtained with a tubular cored electrode and appropriate shielding gas combination as given below.
The classification is divided into five parts:
1) the first part gives a symbol indicating the product/process to be identified;
2) the second part gives a symbol indicating the chemical composition of the all-weld metal;
3) the third part gives a symbol indicating the type of electrode core;
4) the fourth part gives a symbol indicating the shielding gas;
5) the fifth part gives a symbol indicating the welding position.
In order to promote the use of this standard, the classification is split into two sections:
a) Compulsory section
This section includes the symbols for the type of product, the chemical composition, the type of electrode core and the shielding gas, i.e. the symbols defined in 4.1, 4.2, 4.3 and 4.4;
b) Optional section
This section includes the symbols for the welding positions for which the electrode is suitable, i.e. the symbol defined in 4.5.
The full identification (see clause 8) shall be used on packages and in the manufacturer’s literature and data sheets.
4 Symbols and requirements
4.1 Symbol for the product/process
The symbol for the tubular cored electrode used in the metal arc welding process is the letter T.
4.2 Symbol for the chemical composition of all-weld metal
The symbol in Table 1 indicates the chemical composition of all-weld metal determined in accordance with clause 6. The all-weld metal obtained with the tubular cored electrodes in Table 1 under conditions given in clause 5 shall also fulfil the requirements given in Table 2.
