						Description and Applications | 
					
					
						| 
						 
						
						For 
						welding of ships, bridges, and steel frames.  Good slag 
						detachability; X-ray, crack resistance, weld ability, 
						and beautiful beading can be obtained.  |

								| 
								1. | 
								For 
								welding of ships, bridges, and steel frames. 
								Good slag detachability; X-ray, crack 
								resistance, weld ability, and beautiful beading 
								can be obtained. | 
							 
							
								| 
								2. | 
								
								When using 
								recycled flux, it’s better to use the recycled 
								flux mixed with newly made flux to avoid 
								appearance and shape change of the bead. |
