To gas weld, you'll need a gas welding torch that mixes fuel gas with oxygen to create a flame. The workpiece is heated with the flame until it reaches the melting point, and a filler rod is added to create a bond between the two pieces. Practice and proper safety equipment are essential for successful gas welding.
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.
circumfrencial weld is sometimes referred to as Girth weld. its just another term.
Actually Julius Hock invented the first car that runs on liquid gas in 1870 by then their were no Mercedes Benz
First patented in 1810.
The purpose of shielding gas in GTAW (Gas Tungsten Arc Welding) is to protect the weld pool from contaminants in the atmosphere, such as oxygen and nitrogen, that can negatively impact the quality of the weld. The gas creates a protective barrier around the molten metal, preventing oxidation and ensuring a clean, strong weld.
You can glue steel. De-grease it thoroughly first with gas or lacquer thinner, then use J B Weld.
Actualy the first person who invented the first rc car was President Lincon!
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.
the first traffic light was invented in usa i didin't know who invented it the first traffic light was not automatic someone is controling it that what i all know about the trafffic light i don't know who invented the gas mask
