Title: Stainless steel welding bench?
Post by: howsitwork? on February 09, 2018, 05:52:55 PM: Guys
Having seen some very nice welding benches, and got a “reasonable amateur MIG” recently, I wondered about a bench. The garage is a little crowded with cars a Mill, grinders etc so one that could go outside seemed a good idea ? I then thought about a stainless steel bench ex say butchers for example, the intention is to rest work pieces on it having it earthed to the welder and weld resting on it. Are there any issues here I don’t know about? I realise I need to keep the work in contact with the bench a5 all times and probably sand the bench lightly between sessions but is it a goer???

I cou”d add a further earth strap from bench to work piece .

Cheers Ian

I like the idea of aluminum better. You wouldn't have to worry about spatter sticking to it as much, and you're unlikely to weld anything to it accidentally. Conductivity is high and oxidation controlled.

i suggested Al because I've used it very successfully. I had a piece of 2.5mm ish thick plate on the top of a 80cm x 80cm rotary table, no distortion, remember, it is also a very good conductor of heat. No splatter sticking, no accidental welding to it.

I’d never thought of aluminium as surface oxidises so readily so it many thanks for that inspired thought ! :headbang: that’s the great thing about asking for advice on here, you get a breadth of guidance.

Not going to happen soon though as , after club auction last night, there are ba4bains to be “accommodated” before I can actually get into the workshop ! Once I can get in however......
