Marine & Shipbuilding
Commercial or Military. Marine Projects Depend on Welders. Welders Depend on Hobart® Filler Metals.
Durability. Strength. The right filler metal makes all the difference. From large shipyards to recreational boat fabrication, maximize your welding process and efficiency savings. To ensure you meet your customer’s needs, you need filler metals that you can count on: Hobart® filler metals.
Choosing the wrong filler metal can leave you dead in the water.
Weldability is key to shipbuilding, so make sure you have the right material for your projects. Find the best Hobart filler metals from our inventory of materials for every application. We’ll work together to ensure you have the filler metals to deliver the quality your customer expects, just like we did for Marine Group Boat Works.
It’s the tie that binds DURABILITY + STRENGTH
Marine Group Boat Works relies on the strongest filler metals to build U.S. Navy Dive Boats. See why they trust Hobart filler metals to meet demand-critical requirements of dive boats for the U.S. Navy.

Hobart® MaxalMig® 4943
AWS: A5.10: ER4943, R4943
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
Hobart® MaxalMig® 5356
AWS: A5.10: ER5356, R5356
5356 filler metal is the most common aluminum/magnesium alloy for general purpose welding and is typically used in the construction industry in fabricating truck trailers, small fishing boats, and in cryogenic applications. Features/Benefits: – High strength (38 ksi typical) – High ductility/fatigue strength/very high toughness – Moderate ductility/formability – Lower electrical conductivity and thermal conductivity – Higher column strength/better feedability – Very good color match after anodizing with 5xxx/6xxx base materials
