Welding Symblos

Why must welders be able to properly interpret welding​ symbols?

• To be able to answer questions from other welders

• To ensure welds meet design specifications

• To assist design engineers with drawings

• To make welds using the SMAW process

Which of the following does the information in a welding symbol not​ provide?

• Type of weld

• Surface finish of the weld

• Size of the weld

• Discontinuities of the weld

The base for all welding symbols is a​ _____

• ​double-ended arrow line

• vertical reference line with an arrow

• ​T-joint line with an arrow

• horizontal reference line with an arrow

Which part of the welding symbol is not required but is added when​ required?

• Arrow head

• Arrow line

• Tail

• Reference line

When a weld symbol is drawn for a​ fillet, bevel​ groove, J-groove, or flare bevel​ groove, the vertical leg of the symbol is always drawn​ _____.

• to the left

• to the right

• twice the size of the arrow head

• in bold lines

In the case of a bevel groove or​ J-groove where only one side of the joint is to be worked​ on, the arrow in the welding symbol​ _____.

• points to the bevel angle.

• indicates the side to be​ heat-treated.

• shows the direction of weld travel.

• points toward the side to be prepared.

When a combination weld is made by adding a fillet weld to a​ bevel-groove weld in a​ T-joint, how is the fillet weld placed in reference to the groove​ weld?

• To the right side of the fillet weld

• On top of the groove weld

• To the left side of the groove weld

• On the bottom of the groove weld

What is the definition of fillet weld​ size?

• Width of the face from toe to toe

• Length of the legs​ (sides)

• 
  Length of the throat

• Distance from root to face

Where is the length of a fillet weld indicated on a welding​ symbol?

• Above the weld symbol

• Below the weld symbol

• Left of the weld symbol

• Right of the weld symbol

What does it mean if there is no dimension to the right of a fillet weld​ symbol?

• The weld extends the full length of the joint.

• The symbol is unusable if there is no dimension to the right.

• The weld should not be placed in that location.

• The weld extends only 1 ′′ ​(25 mm).
