Yep, but in the plant, a different kind of welding. Resistance to current flow creates the heat. it is not like it would be done by any home or even local shop welder. No filler material is used in the manufacturing process--it's welded simply by pressing the 2 pieces together and passing electrical current between the 2 pieces, instantly fusing them together via the high temperature. A machine does it, welding all the joints in one line at once, then the next line of joints joint moves under the electrodes and it is done--very quickly, with no sacrificial material. At home, we would have to use a filler, either stick or wire feed welder to heat the joint to fusion temps plus add the filler from the wire feed or from the welding rod.I don't think there is even a question as to whether or not you can weld cattle panels, they are created by welding right????
I used to have a single point spot welder, and it worked by the same principle as welded wire and panels, but just one spot at a time.
Here is a sample machine--they all work on the same principle. Action starts about 45 seconds in--you have to watch closely to even see the vertical stays dropped down and welded to the long runners. Blink and you miss them.
