Help On Welding Patch Panels In.
Hello, Im Trying To Weld In My Floor Patch Panels. I Got Them All Fitting Pretty Good And I Drilled Holes In The Panel Where The Floor Supports Are Located, I Tried A Couple Of Tack Welds, But They Didn't Hold. Should I Drill The Hole Through The Supports Also, So The Weld Goes Down In The Hole?

Re: Help On Welding Patch Panels In.
From the sound of it and not knowing the setting / welder combination, I would guess by the description the heat is a bit low. Probably balled the weld up in the top panel not enough heat to get into the lower. If you want to keep this setting you can do it by enlarging the hole and making sure you start the weld on the support brace and then work it into the patch panel. Otherwise add enough heat to get some penetration and it should take care of the problem. If you add heat you will have to watch for burn through.

Re: Help On Welding Patch Panels In.
Sorry, I'm Using A Hobart 180. I Had It Set To 1, Cause I Was Welding Another Patch In. I Just Had It Set Low To Keep From Burning Through. IT SOUNDS LIKE WHAT YOU JUST SAID. THAT MAKES SENSE.

Re: Help On Welding Patch Panels In.

Re: Help On Welding Patch Panels In.
I would suggest getting the panel lightly tacked in place, then the supports. Once you have the floor panel in pretty solid, finish up the supports, then finish the floor panel last. Key is making sure things dont start pulling and warping out of place. You are using a mig?

Re: Help On Welding Patch Panels In.
Yes, As Far As The Welder Setting, Should I Try "2" To Get More Heat?

Re: Help On Welding Patch Panels In.
find two scrap pieces of scrap sheet metal that are close to what the panel and the cad are and practice, that way you can set the welder to good penetration and a speed that you are comfortable with, that is what I did when i replaced the sheetmetal behind the rocker and them welds held. Good Luck

Re: Help On Welding Patch Panels In.
yeah bump up the heat. just watch it so you dont get it too hot.. in all realess its not gana make that much of a difference if your floor pan gets a touch warped, thats more of somthing to worry about when welding on exterior body panels. wouldnt hurt to practice on some scrap either. good luck. dont over think it...

Re: Help On Welding Patch Panels In.
Heat setting is varied by your input voltage. I know that some rural areas have line voltage that is higher or lower. Normal stick welding its not that critical, but when the metal is thinner like in body work you need to keep an eye on how the metal is reacting.
I was in one place using a small Lincoln 125 Mig welder, had all my settings tuned in just so...went to my Dads place and poof..blew right through in a place and said WTF? Turned the setting down a bit and finished the job. Later we checked the voltage and the input voltage was 135! I checked when I got home and it was 115. Not alot but enough to mess you up with thinner metals. Frank

Re: Help On Welding Patch Panels In.
Also, when plug-welding, be sure that the panels are actually touching each other. You need to be sure that you floor panels are in full contact with the supports when you weld them. If you "bridge the gap" when you weld them, the floor will eventually bend between the plug-welds. The floor will be rippled, plus you have left gaps for water to get into....it will and you will have rust, again.

Re: Help On Welding Patch Panels In.
If you are worried about warping just weld a short 3/4 to 1 in bead and move to another side.Let it cool a bit between welds.I agree that warping isn't as big an issue but you don't want it to "oil Can" everytime you step into the truck either.
