AWS Welding Techniques 2

Question 1

Which welding position is designated as '2F' in AWS terminology?

Accepted Answer

Horizontal fillet weld

Answer

The '2F' designation refers to a horizontal fillet weld, where the joint is on a vertical surface and the weld is deposited horizontally.

Question 2

What is the primary purpose of a tack weld in welding operations?

Accepted Answer

To temporarily hold workpieces in alignment before final welding

Answer

Tack welds are small, temporary welds used to hold workpieces in proper alignment and position before the final weld is made.

Question 3

In GMAW (MIG welding), what does 'short-circuit transfer' refer to?

Accepted Answer

Metal transfer where the wire touches the weld pool causing a short circuit

Answer

Short-circuit transfer occurs when the electrode wire contacts the weld pool, causing a short circuit that melts the wire tip and transfers metal at low voltage.

Question 4

What is the recommended travel angle for most flat-position welding passes?

Accepted Answer

5 to 15 degrees

Answer

A travel angle (drag or push) of 5 to 15 degrees from vertical provides good visibility and proper shielding gas coverage in flat-position welding.

Question 5

Which technique is used when welding thin sheet metal to reduce distortion?

Accepted Answer

Backstep welding sequence

Answer

Backstep welding deposits short weld segments in the direction opposite to overall progression, balancing heat input and minimizing distortion on thin materials.
