Alushield Heavy

Benefits

- Produces a flat bead shape with low levels of reinforcement, less clean-up and lower defects
- Can reduce or eliminate the need for preheating due to the increased energy transfer across the welding arc. This is achieved due to the increased helium content producing a focused arc
- Increased welding speeds and lower distortion, whilst maintaining good fusion profiles
- The fluid weld minimises porosity and other defects
- Greater thermal efficiency when used in TIG, MIG and plasma welding copper alloys. Flatter welds with less reinforcement are also produced

General applications

• Commonly used in the MIG welding of aluminium components with thicknesses of greater than 10mm
• Can be used for TIG and plasma welding of components thicker than 6mm
• Suitable for both manual and automatic applications
• Can be used for TIG and plasma welding of carbon and alloy steels where very high welding speeds are required
• The high thermal efficiency of BOC Alushield Heavy can be used to combat the high thermal conductivity of copper. This can reduce the preheat temperature required or length of time preheating must take place for.

Some examples are listed below:

• Armoured vehicles
• Beer barrels
• Electrical components, such as bussbars
• Boilers and pressure systems
• Marine applications
• Architectural and sculpture work
• Copper vessels' production and repair
• Aluminium casting repair
• Aluminium busbars
• Large aluminium fabrications
