Join by melting base material.
It is used for tack welding to retain product shape before brazing, and for joining engine mounts, etc.
Tig welding
Arc welding with non-consumable electrodes.
This method occurs little spatter and secure stable welding quality.
It is used for tack welding before brazing and joints that require airtightness.
Easier to automate the process.

Mig welding
Consumable electrode type arc welding.
It is used at portions where welding strength is required as it can be welded by build-up.
Compared to brazing, one of the advantages is keeping the product shape more stable.
