When you want to weld, there are factors which you must consider in order for you to select an appropriate welding application. The following are the factors to consider:-
- Metal thickness
- Voltage settings
- Shielding gas
- The environment you’re welding in
- Wire feed speed settings
- How you want your work piece to appear.
The above factors will determine if you will use flux core or MIG welding process. MIG welding requires a solid wire electrode and a shielding gas. The shielding gas shields the molten weld pool from contamination form the atmosphere. The shielding gas used in MIG makes the process less portable.
In Flux core welding no shielding gas is required making the process more portable than MIG welding. Flux core welding produces strong welds. However, the strength of the two processes is highly dependent on the welding project and the welding location.
