31、 consistent along the length in order to avoid asymmetrical melting-off of the covering when welding. The electrode covering shall not exhibit any irregularities, cracks or other surface defects, which would adversely affect the welding operation. It shall firmly adhere to the core wire and shall no
32、t break off during proper handling and usage. The grip end of the electrode shall be free from covering material for a length of at least 15 mm. NOTEThe striking end may be provided with arc ignition enhancing material. 5.2 Filler wires, filler rods and strip electrodes The surface of the welding co
33、nsumables shall be free from contamination and surface defects that can adversely affect welding. Any surface finish is allowed, provided that welding operation and properties of the weld metal are not adversely affected. All cored products shall have the core ingredients distributed throughout thei
34、r length with uniformity such that the performance of the products, the chemical composition and the properties of the deposited weld metal thereby are not adversely affected. Filler wires and strip electrodes are delivered in coils or wound on spools in accordance with Figure 1 and Table 4. They sh
35、all not exhibit kinks, waves, sharp bends or other irregularities that could interfere with continuous feeding. The beginning and end of the wire, spooled in one length, shall be secured. Welding consumables on coils without formers shall be tied at three places, at least, approximately equally spac
36、ed around the circumference of the coil. The solid wires and solid wire electrodes for steel shall not exhibit helix greater than described below. Helix is defined as the vertical separation between any part of one loop of wire placed on a flat surface without restraint and the flat surface. It shal
37、l not be more than 25 mm for spools having an outside EN ISO 544:2003 (E) 8 diameter of up to 200 mm (S 200) and not more than 50 mm for spools having a diameter of more than 200 mm (see Table 4). The cast (diameter of some loops of wire placed on a flat surface without restraint), helix and conditi
38、on of all the wires shall be such as to be suitable for uniform uninterrupted feeding on automatic or semi- automatic welding equipment.
