there is a school by me that teaches shielded metal arc welding (SMAW)
What exactly is that? Also what is Oxy-Fuel?


Thanks I stick weld/arc. I want to go to school and get certified.

 

smaw = stick welding

 

oxy fuel is another method of joining metal together, more appropriately its oxygen (oxy) and acetylene (fuel), both gases which come from 2 different cylinders, each gas goes thru a regulator (each one is set at different pressures based on the application) then thru hoses and into a torch, the two gases are mixed in the torch tip and then burned to produce a flame, this flame is hot enough to to melt the work to be joined, forming a molten puddle, from this the ,etals to be joined can either be fuse welded together or filler can be deposited, steel, stainless steel as well as aluminum can ge gas welded, stainless and aluminum will most likely require some type of flux paste

there are 3 different types of flames that can be set with the torch, each flame having a different temperature for the type of work to be done, carburizing (excess acetylene), neutral (equal oxygen and acetylene), and oxidizing (excess oxygen)

a shielding gas is not needed in this process because the outer flame acts as a blanket because it actually consumes the surrouding oxygen around the puddle preventing the puddle from being contaminated

and last i recommend learning this process, im currently in school to get certified and the first thing we were taught was how to gas weld, you learn what welding is all about, puddle control and manipulation, its helps a whole lot once you move onto TIG welding

Wow, That was really detailed to you. I think I will learn that it sounds neat.
