Pros and benefits of TIG Welding
- The non-consumable rod means that the cost, as well as the time is taken to replace said rods in other welding techniques is not an issue.
- Gas tungsten welds don’t always require a metal filler; this offers versatility. You can use a consumable filler metal or not (if you completing an autogenous weld for example).
- Gas tungsten welding is a superb technique for all non-ferrous metals. Copper magnesium and aluminum are no problems for gas tungsten welding.
Cons and limitations
- Weld metal deposition rates are low particularly when used manually.
- Gas tungsten welding is very complicated and requires a high degree of skill, precision and experience; control and accuracy are a must with this technique.
- Speed. Or a lack of it! Gas tungsten welding is slower than other methods which can mean that it is a less productive technique than others in certain situations. If you don’t strictly need to use gas tungsten welding you should probably use another technique.
- There can be health and safety issues as the non-consumable electrode does not have flux coatings that both cover and protect the rods simultaneously. Therefore, there is no smoke screen to cover the light; protective goggles need to be worn by all.
