Frequently asked questions
Brief answers.
What is the difference between MIG and MAG?
Both processes use a consumable wire electrode. MIG uses an inert shielding gas; MAG uses an active one. MAG is commonly used for unalloyed and low-alloy steels. Herdi provides both processes.
Do you weld very large components too?
Yes. Large machines and components, along with extensive welded structures, are among our main MIG/MAG applications.
Do you offer weld surfacing on worn parts?
Yes, weld repairs and surfacing are part of our services.
Key terms explained
- MIG
- Metal inert gas welding. A consumable wire electrode is fed under inert shielding gas.
- MAG
- Metal active gas welding. The same principle with an active shielding gas, commonly used for unalloyed and low-alloy steels.
- Weld surfacing
- Weld metal is deposited onto a surface to build up worn areas or restore components.
