						Description and Applications | 
					
					
						| 
						HM347 is a gas 
						metal arc welding wire to be used with Ar+0.5%∼2.0% O2 
						shield gas. Deposited metal contain Nb. It shows 
						excellent resistance to inter-crystalline corrosion and 
						high temperatures. Welding of SO5347, 321, 304L 
						stainless steels. |

						Guideline in Usage 
						 | 
					
					
						
						
							
								
						
							
								| 
								When high 
								X-ray quality is required, stable spray transfer 
								mode should be maintained with low current and 
								slow welding speed using a pulsed arc and power 
								source. |
