IN SAW WHY SLAG OCCURS?
Why do they use argon gas to tig weld?
Argon gas is an inert gas and it shields the weld from any contamination from the out side air. It shields the weld and makes it cleaner and stronger.
What is the main difference between FCAW and GMAW?
GMAW (solid wire) vs. FCAW (flux-cored wire). The Most important difference between FCAW and GMAW is welding wire,
What is girth weld?
circumfrencial weld is sometimes referred to as Girth weld. its just another term.
Can tig welders be used without gas?
Yes you will not get a "good" weld and it will not be strong The filler electrode used by TIG welder is usually bare and need a shield gas to shield off the atmosphere. Without shield gas, air gets into the molten weld usually produce defects called porosity (air pocket). Your finished weld is defective may not meet the strength. Without a shielding gas you will need more power to establish an arc and the weld puddle will be extremely contaminated (oxidized). The electrode (tungsten) will also be contaminated. You will find the arc wandering all over the place. Use a stick welder instead!
First gas weld equipment was invented in?
1837.
How do you safely weld a gas tank?
I have fixed a couple over time and what I do is fill it with water and detergent empty it out Then do it again, then Weld it.
Can you weld stainless plate to your steel gas tank?

How does calcium carbonate influence weld quality?
Calcium carbonate is decomposed and the products CO/CO2 form a gas shielding for the weld.
How does MAG weld mean?
metal active gas, doing gas metal arc welding with a gas that isn't inert
What do welders need to weld?
