Welding without gas
Greetings sweat fans,
Welding without gas
This article is about welding without gas. Is that even possible, does the whole thing make sense? Or can you really just save the gas when welding?
So I can say quite clearly that gas-shielded arc welding is an umbrella term for MAG or TIG welding, for example.
The whole thing can’t work without gas or without shielding gas, but that’s what the word shielding gas says, and that’s the important point here. Because the gas forms a protective film around the weld pool or molten pool so that no oxygen or dirt gets into the weld seam, which would otherwise be fatal due to pore formation and the weld seam not holding properly.
This applies at least to MAG and TIG welding, where good glass coverage is important.
In TIG welding, the gas coverage can be improved and optimized with gas lenses or simply larger nozzles.
When MAG welding, it is important that the nozzle remains nice and clean and is not full of spatter. The gas flow is then optimally guaranteed.
The situation is completely different with electrode welding, where no protection is required for welding. For this. the electrode is constructed differently here, which virtually takes over.
Important protect yourself NOW simply & cheaply from welding fumes!
There is a lot about welding on our YouTube channel or on Instagram. Take a look at our tips and tricks!
The coating of the electrode melts off during welding, releasing slag and gas, which protects the weld pool.
Flux-cored wire welding also works without gas. This is the same principle as for MAG welding, which is normally carried out with a MAG/MIG welding machine, but here is another example of this with cored wire. is of course great for the private welder because he doesn’t need extra gas.
