Safety Data Sheets

  • An inert gas – will not react to all materials at all temperatures and pressures
  • Produces high-quality welds with good integrity, increased penetration and flatter weld beads
  • Produces improved fusion and reduced defects
  • Improved production rates and cost-efficiencies are achieved by increased welding speeds

Applications Summary

  • Due to Alushield Light’s inert nature, the gas is ideal for use with metals or processes that cannot tolerate the presence of oxidising gases
  • Used in the MIG welding of aluminium components with thicknesses less than 6mm. Can be used for TIG welding aluminium
  • Suitable for both manual and automatic applications
  • Can be used in a wide variety of TIG and MIG applications and fabrication uses, ranging from general aluminium fabrications to shop fittings, piping systems to heat exchangers
  • Used in the aerospace and marine industries, as well as by specialist automotive racing components manufacturers

Material Specific Applications

The following tabled data provides you with a guide to materials and welding processes with which Alushield Light can be used:



Aluminium

 

Process   Typical Use   Example Application   Benefits
MIG welding  
  • Alushield Light is the most used in the
    MIG welding of aluminium components
    with thicknesses less than 6mm. The
    product is suitable for both manual
    and automatic or robotic applications
  
  • General aluminium fabricators
  • Light gauge aluminium buss bars
  • Shop fittings
  • Double glazing units
  • Heat exchanges
  
  • Improved fusion
  • Improved electrical conductivity
    of welding parts.
  
TIG and Plasma welding  
  • Alushield Light is used in TIG and plasma
    welding of components of 3mm and below
    either manually or automatic.
  
  • Piping systems
  • Capping tubing
  • Chemical and pressure vessels
  
  • Improved welding integrity
  • Flatter, faster welds
  • High integrity welds


Copper and Copper Alloys

 

Process   Typical Use   Example Application   Benefit
MIG Welding  
  • The high thermal conductivity of copper
    benefits from the higher thermal efficiency
    of Alushield Light. The product is suited
    for light gauge work where distortion
    control is critical.
  
  • Boilers and pressure systems
  • Marine applications, including
    Monel pipe work
  
  • Improved fusion and
    reduced defects
TIG and plasma welding  
  • The greater thermal efficiency is important
    with TIG and plasma welding copper alloys.
    Flatter welds with less reinforcement are
    also produced.
  
  • Intricate architectural and sculpture
    work
  • Light gauge copper vessels production
    and uses
  
  • Flatter welds, less clean
    up and lower defect rates
    less distortion
    and better fusion

 

Carbon and alloy steels

 

Process   Typical Use   Example Application   Benefits
MIG and plasma brazing   MIG brazing uses copper alloy filler to either fill gaps
between steel components or join steel to copper.		  
  • Automotive industries, filling roof
    to pillar joints
  • Dissimilar joints
  
  • Improved product rates
  • Steel to copper joints on heat
    exchangers
TIG and plasma welding   Alushield Light tends to be used for light gauge TIG
and plasma welding where very high weld speeds
are required such as in pipe and tube mills		        

 

Stainless steel and nickel alloys

 

Process   Typical Use   Example Application   Benefits
TIG and plasma welding  
  • Alushield Light can be used to TIG and plasma
    weld stainless steel and nickel alloys of all grades
    because of its inert nature
  
  • Automatic and robotic
    welding of tubes and pipes
  
  • It has proved possible to significantly
    increasewelding speeds in autogenous
    welding of exhaust systems with the
    added bonus of an extended tungsten life,
    both contributing to increased productivity
    and lower welding costs. 

 

Titanium

 

Process   Typical Use   Example Application   Benefits
TIG and plasma welding  
  • Alushield Light can be used to TIG and plasma
    weld stainless steel and nickel alloys of all
    grades because of its inert nature
  
  • Automatic and robotic welding
    of tubes and pipes
  
  • It has proved possible to significantly
    increase welding speeds in autogenous
    welding of exhaust systems with the
    added bonus of an extended tungsten life,
    both contributing to increased productivity
    and lower welding costs.
