Safety Meeting
This is the shade we use for oxyfuel welding.
SHADE 5
This tool mixes oxygen and fuel gas and allows the welder to control the flame.
What is a TORCH?
This part of the torch holds and directs the flame toward the workpiece.
What is the TIP?
These two colors are commonly used to identify oxygen and acetylene hoses, respectively.
What are GREEN and RED?
A fusion welding process that joins metals by melting the base materials together without adding any external filler metal
AUTOGENOUS
This fuel uses left handed threads.
What is ACETYLENE?
This flame contains excess fuel gas and has a feather-like inner flame cone.
What is a CARBURIZING (reducing) flame?
This is the solution we use to check for leaks.
Soapy water solution.
Acetylene cylinders should be stored and used in this position to keep acetone from entering the regulator and hose.
What is UPRIGHT?
This is the torch angle used.
45 degrees
This safety device prevents a flame from traveling backward into the torch and hoses.
What is a FLASHBACK ARRESTOR?
This type of flame is generally preferred when welding mild steel because it does not add or remove significant carbon from the weld.
What is a NEUTRAL FLAME?
This part of the torch is where the oxygen and fuel gas are mixed before reaching the tip.
What is the MIXING CHAMBER?
Before lighting an oxyfuel torch, this gas should be released briefly to clear contaminants from the hose.
What is OXYGEN?
This process uses oxygen and a fuel gas to melt metal and make a weld without electricity.
What is OXYFUEL WELDING?
This dangerous condition occurs when the flame burns back only a short distance into the torch tip and produces a popping sound.
What is BACKFIRE?
This flame contains excess oxygen and produces a shorter, sharper inner cone.
What is an OXIDIZING flame?
These valves are used to control the pressure of gases coming from the cylinders.
What are REGULATORS?
Acetylene should not normally be used above this pressure because higher pressures can make the gas unstable and dangerous.
What is 15psi?
Removing or lifting the flame off the molten pool to control heat and let the puddle solidify is commonly referred to as...
FLASHING/FLICKING
This term describes the rapid movement of a flame back through the torch toward the mixing chamber.
What is FLASHBACK?
In oxyfuel welding, the flame's hottest region is located just beyond this part of the inner cone.
What is the TIP OF THE INNER CONE?
Before moving an oxy cart, these are the three things we check for.
Is it secure? Chained
Is it under pressure? Regulator screws backed out
Are the regulators zeroed out? Lines bled
This device prevents gas from flowing backward into the opposite hose or gas supply.
What is a CHECK VALVE?
When adjusting a neutral oxyacetylene flame, the inner cone should have this general appearance.
What is a clearly defined, sharp inner cone?
