HOBART

MaxalMig

Alloy 4943 filler metal was formulated to be welded with the same weld procedure specifications as 4043 and 4643, and does not depend upon dilution from the base metal during welding to increase the strength of the weld deposit, while maintaining the same weld characteristics and benefits of 4043 and 4643. Features/Benefits: - 25% higher UTS & 50% higher yield strength than 4043 in the as welded condition (typical) - Moderate/high strength (35 ksi typical) - Low melting temperature/high fluidity - Low welding smut and discoloration - Low ductility, formability, and lower toughness (similar to 4043) - Moderate electrical conductivity and thermal conductivity - Post weld fully heat treatable requiring no base metal dilution - Excellent corrosion resistance - Low shrinkage rate/reduced distortion - Low hot cracking sensitivity in most applications

Welding 6xxx alloys, radiators and air conditioning components, general repair and maintenance, water and gas tight applications, post weld age, post weld heat treat & age applications, automotive/motorcycle frames, sports products - scooters/bicycles, general repair and maintenance, aerospace hardware, ladders and frames, alloy 356 castings, wheels, ship decks, furniture
