    If I am understanding your plans for your welding table correctly, I.E. a series of slats 130 wide by 6mm thick making up your table surface, then I don't know how successful it will be. It doesn't take much to bow 6mm flat bar as you've found out, so the table will be of limited use for setting jobs up flat or holding them flat. In order to recover the job somewhat, could I suggest getting some 40 or 50 X 6 flat bar and stitch welding it on the underside in the middle of your slats to form a T section out of each slat? You will most likely need to straighten them post welding, but at least once they are welded and straightened they will have much better resistance to warping than a plain 6mm flat bar.

    Thanks, I do have some spare flat bar available so might give this a go once I've finished. It was basically a design that I bastardised from the net but didn't see any post reviews about how it performed in practice.

    Hi Guys,

    I must admit that until I saw the picture I thought that the 130 wide had been cut into strips and welded thin edge on.

    If you look at laser or water jet cutting tables they are all relatively thin rigid slats about 35 mm deep with a 90 degree matrix of thin slats underneath supporting them. Looking down at them they look like a framework of squares about 35 mm by 35 mm. And all that is sat on a supporting frame work.

    The way that Yvan has them arranged has very little strength and will bend as soon as any weight is put on them.
    Best Regards:
    Baron J.

    Thanks for the comments and suggestions, may have to do a rethink on the design. The length between the welded on bolts is about 600mm, I am hoping that this will not bow too much but I think I will weld some strips underneath and then try to deal with whatever happens then.

    (BaronJ, I see your location is Nth Yorkshire. That's where I was originally from, been in Oz 7 years now.)

    I just seen your pics and i am thinking how do i tell this bloke that this is the absolute worst welding table design i have laid eyes on.
    Sorry to be blunt but you will have multiple problems with this.
    A welding table needs to be flat, square and have some structural integrity to hold materials firmly in position.
    I suggest that if you want a light weight fabricated welding table then use shs or rhs

    I'm struggling to pick up on the vibe, but, I'm guessing you won't be interested in buying it if I decide to sell?

    Haha, no probs, I'm going to finish it and see how it goes. Can always just weld some RHS onto the channel if it all goes tits up.

    haha....soz...just trying to kick you in a direction where you will have a better outcome.
    Good on you for having a sense of humour AND for having a crack at metalwork

    From my own limited experience, it’s easier to end up with excess heat in the job with TIG that MIG or stick.
    I know it’s harder when you are learning, but if you can crank the TIG up and just get in, weld a short stitch then get out it will help reduce the heat and distortion.

    I'm originally a Castleford child born there just after the war, then parents moved a few miles to Pontefract, then I got married and ended up here just south east of York. Still a Yorkshire man through and through.

    My parents wanted to take advantage of the ten pounds assisted passage to AU when I was about ten or twelve but for some reason it never happened ! I sometimes wonder how different things would have been...

    Sorry to the OP for off topic.

    My late grandfather that I just lost at the age of 97 in January fought the war, then came over on that package with my Nan, mum at 12 and 2 younger sisters.
    They knew no one over here, only some new friends made on the ship over.

    Mum said they where shown videos of beautiful beaches, life styles etc and landed here and had to live in a half dome sheet metal house in Brisbane Queensland in high degee heat.
    It was the middle of winter and his neighbours asked why he had all the windows open in the house, to them it was hot, lol

    My grandad as a boilermaker/shipbuilder worked hard and they moved into a house, then years later packed up with no plans and moved to Newcastle NSW 1000km away, they moved around the Newcastle area over the years and bought several houses that they lived in over the years.

    When they both retired they sold up and went back to in england to live, but it only lasted 6 months and they where back in Australia.

    Hopefully this tells you something about Australia Vs england. I've never left Australia.

    York is one of my favourite places in the UK, always have a couple of nights there when we visit the UK. I was born in Middlesbrough but lived for a long time in Grimsby. I did the backpacking thing in 1990/91 and wanted to live in Aus ever since, was lucky enough to get offered a job on the BG/QGC project in Brisbane but now work for Shell off the coast of Broome.

    Thought I would just update this thread for anyone that is interested. Finished the table a couple of weeks ago. Did end up having to weld some 25mm flat to the back of each strip as someone suggested and it turned out pretty OK for a weekend warrior. I was spending considerably less time at the grinder sharpening tungstens by the end as well so the welding is getting better which is what it was all about. Is it perfectly flat? No of course not but with a bit of adjustment it is perfectly acceptable for the type of work that I am doing at the moment, but I will make another at some stage and spend a bit more money on it.
