Processes
What is SMAW?
Shielded metal arc welding
What protects your eyes and face from intense light and sparks?
Welding hood
The most common basic joint type, where two members are located approximately at right angles to each other, forming a "T" shape.
Commonly used in the field for the flux-covered metal rods used in SMAW
Welding rod
A groove melted into the base metal beside the weld bead
Undercut
What is GMAW?
Gas metal arc welding
This is formed when flux and impurities combine during welding and must be chipped off the cooled weld bead.
Slag
A temporary, small weld used to hold pieces of metal in alignment before the main weld pass.
Tack weld
What does the 60 in E6010 mean?
60,000 pounds of tensile strength
When gases are trapped in the cooling weld before they escape?
porosity
What is GTAW
Gas tungsten arc welding
What is the lowest recommended weld shade when welding?
#10
The number designation for welding in the overhead position
4g
What does the third number on an electrode identify?
The position to be welded in
When slag gets trapped in the molten weld pool and can not be removed
slag inclusion
What is FCAW
Flux cored arc welding
When dealing with an electric shock incident, what type of object should be used to separate the victim from the power source?
Something that is non conductive of electricity such as wooden objects
The part of the weld joint where the two pieces of beveled metal meet at the bottom or innermost point also known as the first pass of the plate
Root pass
What does the last number on an electrode indicate?
Flux makeup
When metal does not fuse together and cases cracks
Lack of fusion
This type of welding is done with a torch at a low temp
Brazing
This safety mechanism activates when a welding machine's duty cycle limit is reached. forcing it to cool down for a percentage of a 10- min period.
Thermal overload shutdown
The preparation method, usually on thicker materials, involves cutting groove into the joint pieces before welding to ensure full penetration
Beveling the plate
This electrode is the most common used for root passes due to its deeper penetration
6010-6011-6013
A distortion of the magnetic field surrounding an arc, when causes the arc to deflect unexpectedly, making it difficult to control the weld puddle.
Arc Blow
