Welding 1.6 mm MS and SS Sheets

Try seam welding, a process which involves 2 rotating copper wheels with applied pressure and electricity to weld a joint.

Thank you for the valuable input.

Hi

In fact we do weld sheets of even 1.2mm thickness.

If MS we use arc welding, but smaller gauge (usually 14 gauge or 12 gauge) is used.

For SS we use TIG.

If you have not done your fitting work properly and tag welded the entire shape first you should not get warping. When you weld do not do it at a stretch. Allow the work piece to cool down a bit in between welding runs.

Hope this info may be of help.

I have welded satinless of this thickness with tig process. It helps to maintain a slight gap in the joint. Weld maybe 6 " of the joint and then cool the area on eash side of the joint with compressed air. This keeps the heat from building up and eliminates much of the creep in the metal. Do not cool the welded area directly but on each side of the weld. This can also be done with mig on thicker material by backsteping the weld and cooling with air. you may need to play with it some to find what works best for you.

TIG welding using small diameter wire shall allow using a little bit ampere which will eliminate heat input into the metal.

Heat input, J/in. (or W-sec./in.) = Volt x Ampere x 60 / (Speed in./min.)

Welding sheet stainless can be a bear unless it is well supported by being tacked down to a solid frame. If the tanks are large enough to get a person inside, I have had good luck using two MIG welders. One on the inside and the other on the outside with one person following a few inches behind the other one. Make sure you follow all safety precautions for a person in an enclosed area if you try this method. Remember, tack the hell out of it before you do any welding and good luck!

Hi,

You should contact Mr James Rodrigues of Arc Plasma at plasmaprince@gmail.com, I am sure, he will solve your pronlem and help much more...

Best luck,

You may contact Mr Karunakaran of GR Industries Coinbatore ( karunakaranpullat@rediffmail.com)who used to supply 0.6( zero.six ) mm SS 316L welded Belts, a huge coil of 1.6 Metre width and 0.6 mm thickness.The dia of joined belt loop will be 1.8 M . The weld was oblique for better stress carrying in Fatigue loading.There was no lack of fusion,or exess penetration ,no distortion, excellent visual characteristics for the 2 Meter long weld.The client was Eltex Coi and then so many others later.

It looked like a tylor's stitch.

DR AK Garg, the head of TIG & Plasma Research Group of Welding Research Institute Tiruchi , India was astonished as he visited there to see it.

Good luck Arvind

Thank you all for the contributions to my discussion. Can anybody suggest me on how to join a 10mm rod to the 1.6 mm sheet. I am thinking of providing supports to my sheets from wobbling. Any help would be appreciated
