4047 filler metal common applications are for thin sections where the higher fluidity and lower shrinkage rate are important for distortion control. 4047 is also used in applications where excellent wetting action for joint sealing of pressurized fluids and gases is required. Features/Benefits: – Low melting temperature/high fluidity – Excellent wetting action for joint sealing applications – Low welding smut and discoloration – Very low ductility, formability, and toughness – Moderate electrical conductivity and thermal conductivity – Excellent corrosion resistance – Very lowest shrinkage rate/reduced distortion – Low hot cracking sensitivity in most applications.

Notice of Usage and Storage
You can do welding directly in effect without any processing before welding after opening the box of products. The products will be effective more than two years on condition that they are of good packing in seal. The products should be put to the place where is of aeration and dryness and away from the medium of acid, alkali, oil and so on. The products should be avoied of crack and damp during delivery so as to avoid destroying the welding spools and impacting the quality of welding wires. We suggest you to put some dust-proof on the surface of the wires after the packages are removed from the products. We suggest you to do some processing to the surface of the wires before welding when you use the wires out of storage life. The arc welding may hurt your eyes during welding. Please protect your eyes.
