E7018-H4R is a filler metal that refers to what welding process?
What is SMAW
100
A reducing oxyfuel gas flame in which there is an excess of fuel gas
What is a "Carburizing Flame"
100
This mode of metal transfer can be used to make out of position welds
What is "Short Circuit"
100
This welding process is known as?
What is GTAW
100
This discontinuity is characterized as being a hole in the weld
What is Porosity
200
PAC is an acronym for this thermal process
What is "Plasma Arc Cutting"
200
A chemical cleaning and purifying agent used to help remove oxides and improve weld quality
What is Flux
200
This determines the direction of electron flow in a welding circuit
What is "Polarity"
200
This Entity creates codes and standards for welding practices
What is "The American Welding Society"
200
This discontinuity is created by the removal of base metal without the addition of weld metal
What is Undercut
300
This welding process was invented in the late 1940's and sees widespread use in manufacturing
What is GMAW
300
The metal or alloy being welded, brazed, soldered, cut, or coated.
What is Base Metal
300
This can be thought of as the force driving the energy in a welding circuit
What is "Voltage"
300
This welding position is known as?
What is 2G
300
This discontinuity is characterized by extra weld metal in a groove joint
What is Excessive Reinforcement
400
This modified short circuit waveform was patented in 2006 and is used to help with fusion related issues
What is "Surface Tension Transfer"
400
A gas heated by an arc to at least a partially ionized condition, enabling it to conduct an electric current.
What is Plasma
400
This material has a protective layer that inhibits it's weldability
What is "Aluminum"
400
This part is used in what welding process?
What is GMAW or FCAW
400
This Discontinuity occurs when a groove joint is not filled to the height of the base metal
What is Underfill
500
This welding process was invented in the early 19th century and has seen widespread use for tasks in more extreme environments
What is SMAW
500
The growing together, or growth into one body, of the materials being joined
What is Coalescence
500
This welding process can either braze or weld depending on the technique and filler metal
What is GTAW
500
This part is found inside of a GMAW lead
What is the "Liner"
500
This discontinuity is present in a groove weld when the material is not joined properly on the backside
What is "Lack of Fusion"
