Project Specific Thread: Welding tables

[Bmxin^Bjorn]

Here's one I built 12 yrs ago out of my scrap pile.It's 13' long and 41''wide ,the beams are 24' 85# and the cross pieces are 18'' 55#.It sets on 8'' steel casters and I have 4 - 1 1/4"jack screws to level or stabilize it.If I need a steel table I just set a piece of plate on it.I built it as a base for building truck bodies and salt spreaders at work and worked out so well the boss wouldn't let me bring it home until I built another one for the shop.It also works good for straightening bent snow plows .

that table is extreamly portable .. you could almost take it to the job site..... if you had a Peterbuilt

What is an ideal height?
This question from "bad back" Jack.

Here is a different idea. I like the lower height working on old farm equipment. The stand was on the place and the grating I bought at a farm sale. About $25 invested.

i built my welding table a few years back, i put caster wheels on mine so i can roll it around where ever i need to as i work or put it in the corner out of the way when not in use.I also use it like a forklift with heavy projects on top of it and roll it where i need it instead of cracking the ole back toting heavy stuff around. I do not have a forklift, have two jib cranes set up and this table works great, caster wheels are cheap at Northern Tool , I went with 4" steel wheels 2000# capacity, fix them up where they can be raised or lowered by using square tubing ,2"x .250 and 2.5" x 3/16 wall so the 2" will slide inside the other, welded a 1" nut on top of the 2.5" with a hole in the top and cap the 2" tube then put a 1" bolt in the nut and you can raise or lower all 4 wheels,weld the casters to the bottom of the 2" tube, and then all you need is a crescent wrench to turn the bolts and bingo! Everyone that comes by my shop are impressed with the setup

I forgot to mention that the tubes are like 8" long , I welded them to the bottom brace that goes around the legs

I was bending the 1" thick top on my table at work when I went to clamp down this 12" "I"-beam base. You can`t see it, but there are two pieces of 3" x 3/8"wall square tubing running the length of the table under the top.



Needless to say, I told the boss that that was not going to work out, and that I needed a better table. He told me to make up a list of what I needed so he could order it. This is what I got a week later:

2" thick blanchard ground top 4' x 10'
10" heavy channel stiffeners
2 1/2" x 1/4" square tube legs
1" leveling bolts on all 8 legs



It`s funny watching our crappy little forklift trying to pick it up.

I posted this in welding table accessory thread:

I wanted to post some pics of some of the welding/work tables I've made (I've made 7). My original table was 4'x6' with a 1/4" welded to the top. I quickly discovered that that warps the top. The tables I'm using these days are are 2x2x.125 square tubing monsters that are designed to hold 1000+ lbs of concrete countertops. Since they have melamine tops on them, I've discovered the best way to weld on them is use 4 large rect. tubing pieces to clamp to and keep the piece off the wood top and also keep the piece level. Anyway here's some pics.







The way I made these tables was to make the top and bottom a mitered square. then I welded 3 cross-pieces in the top and one in the bottom and welded the top and bottom together with 6 verticle pieces (8 on the 10' tables).

As a self-taught welder I've developed a technique that may or may not be correct, but it works for me. I tack-weld everything into place first (two welds at each contact point for sq. tubing). I have a set of cast aluminum 90" braces that I got for $25 each. I clamp onto these braces and tack-weld. I try to do all 4 corners clamped at once if possible. Once THE ENTIRE pieces has been tack welded together I go back and weld strategically to create the greatest strength but not welding enough welds to make it warp. I have never had a weld break on these tables and we use them pretty roughly. I'll weld symmetrically to cut down on warping. Sometimes I'll weld to make it warp in a certain direction.

I wanted to add that one possible advantage of my melamine top tables is that they are extremely portable. I can lift one table myself. I frequently flip the tables on their side and slide them into the back of my pickup. No forklift needed.

I'm definitely getting some great ideas from reading this thread. I'm about to make a 4' square table for home use and like the idea of incorporating ibeams and a vice attachment using trailer hitch stock.

here is mine i built.top has 3/8 x 4 x 8 plate,frame is 2-1/2 x 3-1/2 square tubing.
