RODS
If your rod sticks to your metal, you need to..:
1. Turn up your amps
2. Turn down your amps
3. Change your rod
1. Turn up your amps
You can weld without a welding helmet..:
1. True
2. False
2. False
Why is it important to have a clean welding space?
So you do not get hurt, you won't trip, etc..
What does SMAW stand for?..
Shielded Metal Arc Welding
A student is running 6013, bend looks good, but when bent, the weld breaks off. What is the most likely cause?..
A good looking bead can still break if there is poor penetration.
What are the most used rod(s) around the world
7013 , 6013
If your light is too bright, you should..:
1. Turn up your amps
2. Turn up the shade in your helmet
3. Clean your metal
2. Turn up the shade in your helmet
Name a PPE item..
Gloves, Helmet, Safety Glasses, Coveralls, Leather Shoes
Why does the thickness of the material matter when setting up the welder?..
If your amps are too high and you use too thin of material, the welding rod will burn through your metal.
During a fillet weld, the arc keeps cutting into the base metal. What defects and what caused it?..
Undercutting, caused by high amperage, metal too far apart, and welding too fast.
You cannot see your puddle, you should..:
1. Turn down the shade in your helmet
2. Take your helmet off and weld
3. Chang your rod
1. Turn down the shade in your helmet
What does a clean work space look like?..
A clean workspace is swept, everything is picked up, and shop tools are clean.
Why can too much amps be just as bad as too little amps?..
Too much can burn through the material, and too little won't get enough penetration.
A student tacks one end of the joint before welding, the joint pulls off alignment. Why did this happen?..
Heat Distortion
How often should you clean your helmet..:
1. Never
2. Once a month
3. Once a week
3. Once a week
What safety risk increases when using synthetic clothing when welding?...
Your clothes can catch on fire and burn you
Explain why poor ground connection affects weld quality?..
Poor ground connection affects weld quality because it affects the amps, leading to inconsistent heat input.
2 identical plates are welded together, one cracks while being cooled, the other does not. What factor could cause this difference?..
uneven cooling
Break down what E6013 means..
E- Electrodes
60- Minimum strength per square inch
1- Position
3- Coating
A student leaves several electrodes sitting on a damp workbench, why could this be a problem?..
You could get electrocuted
Why is welding in a drafty area a problem-even with stick welding?..
Poor Penetration
A student welds multiple passes but does not remove slag between passes. What problem could this cause?..
Slag Inclusions
