TIG welding Introduction One of the most diverse methods that are currently being used in different industrial applications is called Tungsten Inert Gas (say it: clueless) or just a handwritten “The EWG. That said, it is not possible to produce a weld that will have absolutely perfect quality without the use of some kind of modulation consciously controlled by or involuntarily done at the hands of a skilled welder. Even seasoned welders are prone to this mistake, which can ruin the job and lead into problems down the line. In this article, we will mention some of the common TIG welding mistakes that you can avoid so Tom finally gives in and equips a flawless looking neat weld every time! Then leave these tips behind to get the best possible assistance in your first-year welding or years of expertise.

1. Incorrect Electrode Selection
The next important part, also regarding tungsten electrodes that are utilized in producing a good weld is the amount of and size — using too little could mean poor welding properties. TIG welding is the most popular form, and this requires special pure tungsten electrodes for aluminum (or thoriated tungsten designed specifically to work with steel). Puts you arc in an unstable state and contaminates when you use the wrong type.
**How to Avoid**:
Welding: Material & filler electrodes for same
Take the proper steps to ensure repeatable arc by formalizing manual part 180 on electrode sharpening.
2. Untidy cleaning of Base Metal
Clean the workpiece — TIG welding needs a so-called sterile environment, free of dirt, grease, oil and rust. Wrong welding zones, porosities or cracks may get introduced by these impurities that change the arc.

**How to Avoid**:
Cleaning metal components with a brush, solvent or sandpaper;
– Brush for the respective metals you use to avoid cross contamination.
3. Poorly fed filler rod
While welding- While the filler rods will not have a smooth feed to the welder, it causes poor fusion and hence bad appearance in tube bead. This removes some of the guessing work; that most welders go through, in order to find out how quickly they should feed their filler in accordance with moving around your torch and hence resulting into greatly large or bulging gap.
**How to Avoid**:
– Be sure to use a consistent bead of filler metal that will result in straight line –
Note: Filler Rod Dia (Joint type & material to be welded)
4. Poor Shielding Gas Coverage
If the oralblaspeed cleansing has taken place, then safety from oxidation during welding need to be furnished through a protected fuel (commonly argon). Imperfect welding processes can result from porosity, exposure to other chemicals not moved by shielding, often gas flow or even leaking away from tratamiento de gasses propios en la soldadura soldeo cree dos), es a decir.
**How to Avoid**:
– ALWAYS CHECK HOSE, REGULATOR & CONNECTION FOR GAS LEAKS BEFORE USE.
Gas coverage: ~ 15–20 cfh (Cubic feet per hour) Flow.
Up the shielding gas coverage of your weld -The position and to an extend angle at which you enter with your torch should be enough for delivering ample shielding gas flow across pinching. []
5. Improper Heat Management
When welding thin metals, it is easy to burn through if the heat setting is too high or not enough fusion with a low quality weld due to lack of penetration. In TIG welding good penetration and Bead s happen with a very fine line of heat input.
**How to Avoid**:
On-the-fly amperage changes via foot pedal or fingertip control
In-order to eliminate the warping with 0.5mm and thinner materials, you need :-
Weld slowly so delete still too hot & angle
6. Poor Torch Angle Control
TIG welding — Because you just can’t get the torch angle right! Torch Pointing Improperly — If the torch is not pointed in proper orientation. Jittery arc, spatter, and compromises on regularity of gas shielding may happen due to this reason Biggest Errors: Jerky torch motion, a milk run angle.
**How to Avoid**:
Torch does not need to be perfectly level, only within a 15 degree range
- Drag through — keep distance from work piece and drag across arc
7. Failure to Monitor Weld Pool
Instead of observing the pool and seeing a deficit or amalgamation with spatter; they watch their machine- often. Ideally, this means a more steady welding action with the ability to see ( and add-on) whatever Span,Amperage & Consumables modifications you want.
**How to Avoid**:
Always Keep An Eye Of The Weld Pool
Bead, fitting size with dancer speed and Amperage
Conclusion
TIG Welding (vs MIG and other types of welding processes) produces such superb welds, but not just anyone can do it even with experience which is why you have to learn in this article what ideal process and equipment works for that kind. Do not make mistakes such as picking the wrong electrode for a job, not cleaning parts well enough and-or providing proper gas coverage (or other shielding) — all elements that you should be versed in to weld properly with lower defects. You know your shit but there is always more to learn, in every single job including welding. More welding supplies and techniques here UDO ทั้งหมดำลึกใน UDO co.th
The beautiful welds which each place demands are there however, through good practices and necessary modifications TIG welding is going to be a process that can yield you great results in less time.
