These processes can differentiate in following aspects.
Difference between Soldering and Welding:
S.No. | Welding | Soldering |
1. | It is used in mechanical industries, like automotive, aerospace etc. | It is used in electrical industries. |
2. | In welding, both work piece are melted together to form a mechanical joint. Sometimes filler material is used to make the joint. | In soldering, a joint is made by use of filler material, known as solder. A rod is heated up to the melting temperature of filler metal. This melted filler metal used to make a joint. |
3. | The welding temperature is above the melting temperature of work piece which is above 3600C | It is done at much below the melting temperature of work piece which is below 400C |
4. | There is change in properties of work piece. | There is no change in properties. |
5. | It forms strong mechanical joint. | It forms strong electrical joint. |
6. | Filler material is not compulsory. | Filler material is compulsory in soldering. |
7. | It can withstand with high temperature. | It cannot withstand with high temperature. |
8. | The work piece should be clean below welding. | It is not compulsory to clean work piece before joining. |
9. | Special training is required to perform the welding. | No special training is required to perform it. |
10. | Preheating of work piece is not required. | Preheating of work piece is not compulsory but it may give good result. |
