Shielded welding needs a gas to shield the weld from the atmoshere air. Unshielded uses a flux the burns when welding to shield the weld from the atmoshere air.
Used in welding metals, the reaction of acetylene with oxygen has = -1256.2= -1256.2 .

Yes, propylene (propene) can be used for welding.
Thermite welding is all about using thermite for welding steel or iron. Thermite is actually a mixture of iron oxide and powdered aluminum.
Yes, arc welding does create ozone. It is because the temperatures created during arc welding convert the nearby oxygen to ozone.
Shielded Metal Arc Welding, known colloquially as "stick".
Shielded Metal Arc Welding, commonly called Stick welding. A shielded electrode passes a current between itself and the workpiece. Both the base-metal and the electrode are melted by the current and the electrode is consumed and deposited into the melted puddle forming the weldment.

The difference in the ac/ dc , or polarity of welding rods is in the makeup of the flux coating , or the alloy of the metal, and in the case of SMAW ( Shielded metal arc welding ) rods , which have a flux coating, are usually marked on the base of the rod.
