Default Welding question

Hey I didn't know where else to post this and i could not find anything on google or youtube (mainly cause i don't know what they are called?). I am trying to find out the reason behind the reversed screws when welding. I noticed some screws pointing upwards then they cut them off and grind them. Can someone tell me or point me to a video that provides more info as to why this is done?

thanks.

sounds like your referring to the studs that are welded on for dent pulling.




the only other thing I can think of is using self tapping crews to hold part together before welding. I've done this to hold parts together while I align things, but I don't run them from the back side, I just remove them as I go and plug weld the holes.

Can you give us a reference to where you have seen this done, then perhaps we can tell what your inquiring about. For your question and its description I can think of about a dozen different variations and scenarios you could be talking about.....?

it looks like it may have been dent pulling. I found a little video about the self tapping screws but dont know how to use them. (Forgot to mention im not a welder of any sort, just saw it and couldn't find anything on it. Figure who better to ask than the subie community? )

Dangerousatom, Can you tell me a few other things you could think of that it may be? (if you dont mind, for some reason I found it intriguing the screws or rods sticking out and what it may be used for)

Again, thanks for replying much appreciated.

It all depends on were and on what its done.....

-Sheet metal body = 99% of the time is pulling a dent
-If its a lap joint on structural steel then its usually to secure the metal in place long with clamps
-Some times a series of bolts are used to preload a section of plate steel joints before welding them into one complete section

and before these stud welders, i know people used to screw in studs into the sheet metal and pull it that way. but then you had to fix the damn holes afterwards.

i do bodywork for a living and please dont screw screws in the panel it will need to be welded after or ull have corrosion issues, Also the nail gun in the picture welds studs on the panel and causes corrosion on the back of the panel which u will have to spray with an anti corrosion spray.
