Exam 6: Fabricating Techniques and Practices

Pipe clamps are very similar to C-clamps.

The metals with the higher values of coefficients of expansion tend to distort more during welding.

To start the assembly, make a selection of the largest or most central part to be the base for your assembly.

The two factors that affect the degree to which a metal will distort and possibly remain distorted are its rate of thermal expansion and its rate of ____________________.

____ are the welds, usually small in size, that are made during the assembly to hold all of the parts of a weldment together so they can be finish-welded.

All cutting processes except shearing remove some metal, leaving a small gap or space. This gap or space is called the ____.

Circles, arcs, and curves can be laid out by either using a compass or circle ____________________.

Every part manufactured has a tolerance.

The opposite end of the spectrum from preformed parts is ____.

A(n) ____________________ is an assembly whose parts may be joined by a combination of methods including welds, bolts, screws, adhesives, and so on.

The first step in almost every welding operation is the assembly of the parts to be joined by welding.

A variety of types of ____ can be used to temporarily hold parts in place so that they can be tack welded.

The two most common gauge standards are the Manufacturer's Standard Gauge for Sheet Steel and the ____.

When making an assembly with precut and formed parts, little or no on-the-job ____________________ may be required.

Most welding heat cycling is symmetrical.

In addition to straight welding, welders are often required to assemble parts together to form a ____.

Either a scribe or a punch can be used to lay out an accurate line.

Tubing sizes are always given as the outside ____________________.

Large welds may cause great ____ and have larger heat affected zones.

____ are devices that are made to aid in assemblies and fabrication of weldments.
