Stick Welding Flashcards
What does SMAW stand for?
Shielded metal arc welding
What power source is used in stick?
CC = constant current
Can you adjust the amperage on CC power sources?
Yes
What are two names for the electrode holder?
Clamp type
twist locking
What is the work ( ground) clamp?
Completes the welding circuit
When lens should be used for 60 amps and under?
7
What lens should be used for 60 - 160 amps
8-10
What lens should be used for 160-250
10-12
What lens should be used at 250 - 550 amps
11-14
What is a magnifier?
Can be secured behind the inside cover plate to make it easier to see very fine details when welding small intricate pieces
What is the common temperature of stick welding?
6500 C (4000F)
How are gases used in SMAW process ?
Flux burned of the electrode
What does slag do?
Protects the weld during cooling
What would the minimum temperature of A rod oven be?
120c (250f)
What should you do with rods that have been exposed to air for an extended period of time?
Dried for 1 hour between 370 -430c ( 700-800F)
What type of rods don’t go in the oven?
E 6010
What rods must be kept dry?
Low hydrogen
What does the 3 mean in the third digit in a rod code?
Can be used in flat only position
What weld goes on the bottom of a gap?
Root weld
What weld fills the most space and gives the most strength?
A filler weld
In terms of electrode identification what numbers indicate No over’
0 and 1 for type of coating
Fast freeze, what does it mean?
Takes from quickly ideal for horizontal and overhead
Fast fill, what does it mean?
Electrode with a high deposit rate
If your amperage is too high, what are the signs?
Rod will turn red, weld is red 3/4 inch after stopping arc
What is a keyhole in terms of stick?
Slight groove on The end/ beginning of the weld indicating proper penetration
