Welding, soldering, and brazing are all techniques of connecting two or more metals or, in certain situations, other materials. They can also be used to fill gaps in metal parts. So how do you choose which technique to employ? This decision is influenced by the materials, desired strength, and application. Let us check out the difference between welding and soldering here in this article.
Difference between welding and soldering:
- Welding joints are stronger in comparison to soldering joints.
- Soldering requires preheating of workpieces but no preheating of workpieces is required in the welding process.
- In welding the base metal changes its mechanical properties due to cooling and heating, Base metal does not have a significant effect on their mechanical properties in soldering.
- Base metals in the welding process are heated to melt and create a strong bond whereas in soldering base metals require no heating or melting.
- Heat treatment is the process where metals' physical and chemical properties are altered by heating and cooling it back. This is common in welding techniques but not in soldering.
- A welder and solder are both professional workers who require skills and experience in their assigned job. Welding works are frequently found in the automotive, industrial, and construction industries. Soldering is mostly used in the electronic sector.
- Different metals need different temperatures in order to melt and form a connection. Steel variant is usually used in welding may require a temperature between 3000 degrees Celsius and 20000 degrees celsius. Soldering on the other hand will require roughly 350-450 degrees celsius.
