Why choose resistance welding? [RW04]

Dec 28,2023

Why choose resistance welding? What are the advantages of resistance welding?

These questions have been asked many times, and I am happy to discuss it with the welding experts who question resistance welding.

I think it's fair for people who build bridges, buildings, or other steel structures to raise these questions. But let me make it clear: I'm not saying that resistance welding is the only available welding process. I am stating that because of its unique advantages, resistance welding should be considered first in the selection of welding processes for connecting metals. Admittedly, resistance welding is not suitable for all situations, but it does have a number of applications where it can provide positive attributes that other welding processes can not match. You ask me, “Why choose resistance welding?” And I'll answer your question on its merits.

Advantages of resistance welding

1.The operation cost of resistance welding is low.

2.No need to fill any metal in welding, the weld is made up of two pieces of metal to be welded.

3.No protective gas or flux is required.

4.Resistance welding speed is fast. Some resistance welding can be completed in two milliseconds. No welding method can be faster than this speed.

5.The welding process is clean and, if done correctly, produces little soot.

6.It is easy to automate welding process by using computer hardware and robots.

1.It is quite convenient to install resistance welding equipment .

2.Except in rare cases, resistance welding is not sensitive to operator proficiency, which is a great advantage. The operator can do all the work by manipulating the welding equipment, such as setting control parameters, detecting the welding process by the sensor, and giving good feedback of welding.

3.The weld connection is of high strength and good durability. The welding process can be repeated and verified.
