Union AlMg 4,5 Mn Zr

Rods for GTAW of AlMg containing up to 3% Mg. Seawater-resistant weld metal. Good colour matching with base metal after anodizing. Base material should be cleaned near the seam. Pre-heating 150°C for plates > 15 mm.

Solid wire for GMAW of AlMg alloys containing up to 5% Mg. Seawater-resistant weld metal. Susceptible to stress corrosion cracking if exposed to service temperatures > 65°C. Good colour matching with base metal after anodizing. Thorough cleaning of the workpiece bevels is necessary prior to welding.

Solid wire for GMAW of AlMg alloys containing up to 5% Mg. Seawater-resistant weld metal. Susceptible to stress corrosion cracking if exposed to service temperatures > 65°C. Good colour matching with base metal after anodizing. The welding consumable contains Ti for grain refinery. Thorough cleaning of the workpiece bevels is necessary prior to welding.

UTP 485 is an aluminium stick electrode with 5% Si and a special coating. It is suitable for joining and surfacing AlSi alloys with a Si content of up to 7% and for dissimilar joints of different Al-alloys, such as: 3.3206 AlMgSi 0.5 - 3.2371 G-AlSi 7 Mg 3.3210 AlMgSi 0.7 - 3.2341 G-AlSi 5 Mg 3.2315 AlMgSi 1 - 3.2151 G-AlSi 6 Cu 4 3.3211 AlMg 1 SiCu UTP 485 is suitable for welding plates of wall thicknesses> 2 mm. The soft arc produces a fl at, fi newly-rippled weld seam. Easy slag removal.
