Austria Bole E8010 electrodes meet the GB E5510-G 
 Rather AWS E8010-G 
 Note: E8010 is a high cellulose sodium type vertical down welding. Arc blowing force, welding gas, residue conservation, less slag, easy to clean, solder wave forming beautiful, welding speed, deposited metal has good mechanical properties and excellent resistance to pore and crack resistance, is the pipeline field girth weld all position-specific vertical down welding, the use of DCRP. 
 Uses: used for the same strength grade carbon steel, low alloy steel pipes filled, capping, also suitable for the general strength of structures with vertical down welding. 

 J507FeXG cellulose electrodes meet the GB E5048 to under the 
 Very AWS E7048 
 Description: E507FeXG is a low hydrogen iron powder electrode sodium channels dedicated, vertical down welding, the slag no less than drip, arc stability, and a little wind power, easy slag, welding wave formation, with good mechanical properties and crack performance, high deposition efficiency. 
 Application: thickness ≤ 9mm tube down welding, fillet welding and downlink downlink groove butt welding, the thickness can also be used> 9mm backing weld pipe down. 

 To the electrode under J507XG cellulose found GB E5015 
 Very AWS E7015 
 Description: E507XG is a low hydrogen sodium type coating, pipe welding vertical down welding of special steel. It features vertical down welding, the slag does not drip, arc stability, and a certain wind power, easy slag, welding wave formation. DC power supply, connected to the positive electrode. Has good mechanical properties and crack resistance. 
 Application: Suitable for welding thickness ≤ 9mm down and down tube fillet welding, butt down groove welding, can also be used for the thickness of> 9mm backing weld pipe down. 

 Next to cellulose found J556FeXG GB E5518-G electrode 
 Rather AWS E8018-G 
 Description: E556FeXG is a low hydrogen potassium type coating iron pipe special electrode, which is characterized by no less than trickle down slag welding, arc stability, and a little wind power, easier slag, welding wave formation, deposition efficiency than the high, with good mechanical properties and crack resistance. AC and DC, DCRP welding, the effect is better. 
 Application: the corresponding strength grade carbon steel and low alloy steel tube filled with capping, can also be used with the hierarchical structure of welded steel angle down, down butt weld groove.
