2. Is spot welding fusion welding?
Ans: Spot welding is a fusion welding technique that needs pressure and heat to make a stronger joint.
3. How strong is a spot weld?
Spot welding allows you to join two pieces of metal together quickly and efficiently. But the joining by spot welding is not enough for all plans…..
It might be defective or weak, mainly if the process is not applied correctly. Basically, spot welding joins two metal sheets by using heat from the electric flow.
The metal sheets are pressed together, either part with electrodes. A small spot joins the electrodes. The current needs to be used for the right amount of time to get strong welding.
Usually, spot welding provides current for 0.1 seconds or less, so it needs a high voltage current. Spot welder needs 100,000 to 200,000 watts to complete the welding job.
4. What materials can be spot welded?
Spot welding is also known as resistance welding, which is ideal for different metal sheet welding. Let’s take a look at the possible materials that can be spot welded.
- Stainless steel
- Nickel coated steel
- Nickel alloys and
We are at the end of this review. Before wrapping up, let me recap what is the best spot welder.
