Testing Methods
This NDT method is best for detecting subsurface discontinuities and measuring their depth.
What is Ultrasonic Testing (UT)?
This document is to provide detailed information for a specific welding job.
What is a WPS (welding procedure specification)?
This is the primary cause of incomplete fusion.
What is insufficient heat input.
This is the name of the welding position for fillet welds in the flat position.
What is the 1F position?
This is the recommended method for removing surface discontinuities like spatters before inspection.
What is grinding?
This NDT method uses x-rays or gamma rays to detect internal defects.
What is Radiographic testing (RT)?
Verifying the welder's skill is the main purpose of this.
What is a welding qualification test?
This type of weld defect is caused by rapid cooling of the weld metal.
What is cracking?
This is the name of the welding position for fillet welds in the overhead position.
What is the 4F Position?
This welding process is most susceptible to slag inclusions
What is Shielded Metal Arc Welding (SMAW)?
These are the two bends that are required of material up to 3/8" thick.
What is a face bend and a root bend?
In a welding procedure, this is something that cannot be changed without requalification.
What is an essential variable?
This type of discontinuity is characterized by a sharp break or crack in the weld metal.
What is a fracture?
This is the name of the welding position for groove welds in the vertical position.
Excessive spatter and a wide bead is a potential consequence of this.
What is excessive voltage?
This NDT method is best suited for detecting surface cracks in welds.
What is liquid penetrant testing (PT)?
This document is a record of WPS qualification test results.
What is a procedure qualification record (PQR)?
This is one common cause of porosity in welds.
What is contamination during welding?
According to the AWS structural steel code, qualifying for higher F-number electrodes qualifies the welder for this.
What is lower F-numbers?
when using this tool, it should be flush with the base, with the tip of the tool vertical on the vertical weldment.
What is a fillet weld blade gauge?
This is a destructive welding test, commonly used when qualifying welders.
What is a guided bend test?
These types of welds are required for AWS 3G and 4G qualification.
What is a V-groove weld with backing?
This welding defect is characterized by weld metal extending beyond the toe or root.
What is overlap?
When a welder qualifies on pipe, they also qualify for this. It does not work the other way around.
What is plate?
Only ferrous metals can be tested using this NDT.
What is Magnetic particle testing (MT)?
