Autogrnous weld |
A fusion weld made without filler metal. Actual throat |
|
|
Actual throat |
The shortest distance between the weld root and the face of a fillet weld. |
|
|
Theoretical throat |
The distance from the beginning of the joint riot perpendicular to the hypotenuse of the largest right triangle that can be inscribed within the cross section of a fillet weld. This dimension is based on the assumption that the root opening is equal to zero. |
|
|
What is the least desirable GMAW type of transfer? |
Globular transfer- tendency to produce high heat, poor weld surface, weld spatter or cold lap. |
|
|
GMAW- what are the transfer modes? (4) |
Short circuiting Globular Spray Pulsed |
|
|
Self shielding FCAW is typically not recommended for? |
Pressure containing welds |
|
|
VT examination |
Eyes within 6 to 24" (figure 14 does not agree and stated 6 to 12", you have the right to protest answer)
Angle not less than 30 degrees |
|
|
Remote devices can be used for inspection as they have at least the resolution as direct visual observation. Which types are acceptable? |
Telescope, cameras, borescope, fiberscope. |
|
|
Where to find requirements for visual examination? |
ASME Sec V Art 9 |
|
|
What electrodes may be used for root and hot passes? |
Cellulosic type (E6010, E6011, E7010) |
|
|
When performing hot tapping and in service welding, two primary concerns are? |
Burn through and cracking |
|
|
Which type of electrode has deep penetration, therefore higher risk of burn through than low hydrogen electrodes. |
Cellulosic |
|
|
To avoid overheating and burn through, welding procedure specification should be based on experience in performing welding operations on similar piping or equipment, and/or based on? |
Heat transfer analysis |
|
|
Definition of density of a material? |
Mass per unit volume. |
|
|
Hardening or hardenability |
That property of a ferrous alloy that determines the depth and distribution of hardness induced by quenching. |
