Question 1

____ flange joints are used for light metals.&#10;A) Edge&#10;B) Scarf&#10;C) Bevel&#10;D) V-groove

Accepted Answer

Edge flange joints are used for light metals because they provide a simple and effective way to join these materials without the need for heavy welding or complex fastening methods.

Question 2

____ flange joints are used for light metals.&#10;A) Scarf&#10;B) Bevel&#10;C) V-groove&#10;D) Corner

Accepted Answer

Corner flange joints are typically used for light metals as they provide a simple and effective way to join two pieces at a right angle, which is common in light metal constructions.

Question 3

The design of the structure may require a joint spacing or root opening (gap) between members being welded.

Accepted Answer

Yes, the design of the structure may require a joint spacing or root opening (gap) between members being welded. This is because different welding techniques require different joint spacing and root openings to achieve the desired strength and integrity of the weld.

Question 4

The selection of the weld is based on a few, limited factors.

Accepted Answer

The selection of the weld is based on a variety of factors including the type of base material, joint design, strength requirements, corrosion resistance, and service conditions.

Question 5

A joint spacing or root opening (gap) between members being welded is indicated by welding symbols or ___________________ on the print.

Accepted Answer

The answer of A joint spacing or root opening (gap)...

Question 6

The design of the weld and/or the groove is usually the function of the ____________________.

Accepted Answer

The answer of The design of the weld and/or the...

Question 7

Joints for structural shapes may also be formed by ____ the members.&#10;A) bending&#10;B) cutting and bending&#10;C) cutting&#10;D) bending and shaping

Accepted Answer

To form joints for structural shapes, the members need to be cut and bent to the required shape and size. This is necessary to ensure a strong and secure connection between the members, which can withstand the loads and stresses that will act on the structure. Cutting and bending allows for precise fitting of the members, and also ensures that the joint is flush and free from any gaps or irregularities. Bending alone may not be sufficient to form a joint, as it may not provide the required level of strength and stability. Likewise, cutting alone may create weak points in the structure, which can compromise its overall integrity. Therefore, cutting and bending are both essential processes in forming joints for structural shapes.

Question 8

The ____________________ joint is used for brazed weldments.

Accepted Answer

The answer of The ____________________ joint is used for brazed...

Question 9

The flare ____ joints are used in weldments of heavier gage materials where one or two of the members have a curved shape.&#10;A) edge&#10;B) V-groove&#10;C) scarf&#10;D) corner

Accepted Answer

Flare V-groove joints are designed to accommodate curved shapes, making them the best choice for heavier gauge materials. The V-groove design ensures full penetration of the joint and provides a smooth contour, reducing stress concentrations in the weld. The edge, scarf, and corner joints are not designed to accommodate curved shapes and may not provide the necessary strength and performance for heavier gauge materials.

Question 10

The flare ____ joints are used in weldments of heavier gage materials where one or two of the members have a curved shape.&#10;A) corner&#10;B) scarf&#10;C) edge&#10;D) bevel

Accepted Answer

Bevel flares are used in weldments of heavier gage materials where one or two of the members have a curved shape.

Question 11

Members of the joints to be welded may be formed to a particular shape in preparation for the weld to increase the ____ of the joint.&#10;A) strength&#10;B) durability&#10;C) longevity&#10;D) worth

Accepted Answer

The answer of Members of the joints to be welded...

Question 12

In certain cases, cutting and bending members to create joins for structural shapes may be more economical, even though more cutting and welding are required.

Accepted Answer

The answer of In certain cases, cutting and bending members...

Question 13

Standard welding ____ are used to indicate the welds required.&#10;A) objects&#10;B) marks&#10;C) symbols&#10;D) indicators

Accepted Answer

The answer of Standard welding ____ are used to indicate...

Question 14

When a grooved joint is required on heavy structural shapes, it may be possible to provide for a groove without formal preparation of the joint members.

Accepted Answer

The answer of When a grooved joint is required on...

Question 15

The basic joints used for weldment fabrications are: ____.&#10;A) corner, lap, and butt&#10;B) edge, corner, lee, and lap&#10;C) butt, corner, tee, lap, and edge&#10;D) butt, corner, and edge

Accepted Answer

The answer of The basic joints used for weldment fabrications...

Question 16

For each type of joint, a number of different welds may be applied.

Accepted Answer

The answer of For each type of joint, a number...

Question 17

Members of the joints to be welded may be formed to a particular shape in preparation for the weld to improve the ____ of the weldment.&#10;A) worth&#10;B) longevity&#10;C) appearance&#10;D) quality
