In this article, we discussed Mig and Tig welding and welding defects. As a welder, we think it will help you to get some necessary information about welding types.
MiG Welding:
Welding using welding electrodes, using a decaying wire in the continuous flow of inactive gas, such as argon, helium etc., is called Mig welding. In this, electrodes themselves work as fillers rods.
The Mig welding used in the metals are:
- Carbon steel
- Low pay steel
- Heat Resistant Stee
- Hybrids used for welding.
1. Deep painting welding can be made.
2. Both thick and thin jaws can be properly welded.
3. The metal deposition rate is higher
4. No need to use the flux.
5. Smooth and neat fused stars are made.
6. Cost less.
Tig Welding:
Welding using welded electrodes in the welding process of a continuous flux of inactive gas such as argon, helium etc. is called tig welding. It does not apply filler rod.
The application areas of Tig welding are:
1. Aircraft manufacturing factory
2. In the chemical industry
3. Food Processing
4. Liquor factory
5. Welding the root line of the pipeline.
The advantages of tig welding are:
1. The welding floor is smooth and flat.
2. No spatter is produced.
3. The chorus does not deliver
4. Slug is not created.
What are the welding defects?
1. Distorted: If the original metal is heated indefinitely, it is changed due to collapsing and crunching due to the contraction and expansion during the cold.
2. Undercut: Extra heated and faulty weld motions cause the cutting edge of the metal and weld metal cutting line to make an uneven line. It is the undercut.
3. Incomplete PENETRATION: Inadequate and less intrinsic insides inside the original metal are called incomplete PENETRATION.
4. Excess PENETRATION: When the extra weld metal enters the welding pair, it is known as the magnitude penalty.
5. Spatter: Sprayers are spread around molten metal and spread out as spatter.
6. Overlap: If the base metal does not override the base metal, then the magnitude of the metal is overlaid on it, it is called duplication.
7. Crack: Due to the additional current flow it occurs.
Conclusion:
We hope in this short and article you got a brief idea about Mig and Tig welding. Remember the welding defects so that you can recover these while your welding projects. As a welder, you also know what the best Mig welder and tig welder is. Happy Welding.
