3 / 52
this handbook examines tig and mig/mag
welding
. tig
welding
uses a non-consumable tungsten electrode and is short for “tungsten inert gas”. mig/mag
welding
uses solid or cored wire as the electrode, fed continuously into the arc. mig is short for “metal inert gas” and mag is short for “metal active gas”. introduction the
welding
world wants to constantly improve productivity, quality and the work environment. the construction materials, filler materials and power sources are developing,
welding
parameters change and new
shielding
gases
are introduced. the purpose of this handbook is to give a useful overall picture of the
shielding
gases
available for gas arc
welding
. the handbook describes the significance of
shielding
gases
on the
welding
process and their effect on productivity, quality and the work environment. it also gives you guidance in selecting the
shielding
gas best suited to each
welding
method and base material from the wide selection of
shielding
gases
, and answers frequently asked questions concerning the purpose, selection and effects of
shielding
gases
. if you wish to know which
shielding
gas is best suited to your
welding
work, you can find the answer in chapters 7–9. if you wish to find out the base materials for which a specific
shielding
gas is designed, you can find the answer in chapter 10, “applications of
shielding
gases
”. if you cannot find answers to all of your questions in this handbook, you can always ask aga for more information.you can find our contact information from the back cover of this handbook. introduction. ® mison, rapid processing, odorox, formier, corgon, cronigon and varigon are registered trademarks of the linde group. introduction 3
