BÖHLER UNION ALSI 5 4043A 3.2mm x 1000mm tig wire 2.5kg

Description

BÖHLER UNION ALSi 5 4043A 3.2 x 1000mm Tig Wire is a premium-grade welding rod crafted for precision in aluminium-silicon (AlSi) alloy welding. This Tig wire can be used for a wide range of applications, ensuring smooth and clean welds with minimal spatter and distortion.

Key Features:

• Designed for gas tungsten arc welding (GTAW) of aluminium-silicon alloys with silicon content up to 5%.
• Suitable for oxyacetylene welding or brazing with appropriate fluxes, offering flexibility in welding processes.
• The weld metal is not suitable for anodizing for decorative purposes.
• Produces a very fluid weld pool, facilitating smooth and clean welds with minimal spatter and distortion.
• Base material should be thoroughly cleaned near the seam to ensure optimal weld quality and integrity.
• Pre-heating between 150°C to 200°C is recommended for plates thicker than 15 mm to minimise cracking and improve weldability.
• Not suitable for welding hardenable alloys in high-stress zones.
