Welding Flashcards
What is the website the video is from?
HOWCAST.com
Name of the host?
DeWitt Godfrey
What other ways apart from welding did he mention?
Soldering and Glazing
How did he define welding?
With welding you take 2 distinct objects, and through the addition of heat, we create a molten pool of metal to which they add a filler rod.
What is the result of welding?
Instead of 2 distinct pieces, you get a homogenous piece of material that can be bent, cut, or manipulated in any way.
What are the different types of welding that he says exist?
Gas (acetylene & oxygen), Mig welding, Arc welding, and Tig welding (electrical source to create heat)
What is the first type of welding that he is shown doing?
OXY-FUEL GAS WELDING
What are the items he uses in oxy-fuel gas welding?
Goggles, Torch, acetylene (Flint Torch Lighter), and Filler rod
What was the final color of the flame when he started welding?
Bright Blue
How did he get the blue flame?
Started with the acetylene, then used a Flint Torch Lighter, and finally added oxygen to make the flame burn brighter
What did he say was the hottest part of the flame?
At the tip of the blue bright seam
What is the PPE that he was wearing?
Leather Gloves, Leather Jacket, Goggles and Glasses
What was the material that he was heating up?
Steel
When does he start adding in the filler material (filler rod)?
When the part is red and shiny
What was the end product after the welding was finished?
2 pieces joined together, with a bead across the seam they are connected at and a HAZ (heat affected zone) surrounding the welded area
