Weld thickness is generally the depth of the weld, for example a fillet weld, you would be measuring with a fillet gauge, picture a line at 45 degrees, from the top to the point where the two plates meet.

 

I think in your specific situation, that's the thickness of metal you can weld. MIG and TIG are both good for thin metal. With TIG you can have a lot more control over the weld, so you might say TIG is better for thin metal.

I don't think "weld thickness" is a welding term. It refers to a dimension but without a number and a unit, it is subjective and pretty much meaningless.


To someone who welds car panels, thick might be 3 mm. To someone who welds cranes, thick might be 50 mm.

With reference to your example, someone, in an undefined context, thinks TIG welding is better for thinner material and MIG (dip?, spray?, pulse?) for thicker material.

If thin is 1 mm Al sheet and thick is 3 mm Al sheet then yes, TIG would probably be better for the thin stuff but could do the thick stuff just as easily.

simply put, it arose of the need to answer (or solve confusion on) wondering that:

TIG cannot join two same type metal which is either one is or both are thick, at least 17 mm or 3/4 inch, in any way absolutely ?

Please help elaborate it comprehensively.

huh??????????

 

To me thin is anything you can easily burn thru, say anything under 1/8", and thick is 1/8" and above.

 

What is the exact definition of weld thickness, as in so commonly, often said 'The M

"so commonly often said", and "exact", dont so much go togethr to me anyway, not only in welding, but alot of things. reason "thickness" caught my eye hear, cuz i remeber being given a written weld procedure written by structural engineer, talking of max thickness of weld/stringers. different types of throats, but my best educated guess was, he meant, theoretical throat

 

I think we are confusing deposition and throat with "thickness".

 

Perhaps more clarity is needed but the metal to be welded is 3/4" thick - it seems we are referring to the "thickness" of the metal to be welded.

I'm qualified to tig weld up to 17mm thickness material from one side with vee butt prep. I can weld double that thickness by double vee welding from both sides. If I want to weld thicker I 'd have to qualify another procedure.
So anything is possible, whether it's efficient is another question.
