API 1104

For this training you need a copy of:
API 1104 20th
ERRATA / ADDENDUM JULY 2007
ERRATA 2, DECEMBER 2008

All codes, standards, specifications, and guides are conceptually similar, but
each
hh
has a specific
ifi application
li ti and
d purpose.
API 1104 is a good example of the concept, so learning to use this code will
help
p yyou learn to use others as well.
API 1104 applies to welding of piping used in the compression, pumping, and
transmission of petroleum products, fuel gases, carbon dioxide, and nitrogen.
The standard's purpose is to present methods for the production and
inspection of high-quality welds through the use of qualified personnel using
approved
pp
p
procedures, materials, and equipment.
q p
It applies
pp
to new
construction and in-service welding.

Definitions
API 1104 Section 3, Definition of Terms, presents a list of definitions of
welding terms based upon AWS 3.0, Standard Welding Terms and Definitions.
Less than or greater than
In many codes and standards, including API 1104, the rules vary depending on the
size of a p
part,, intended service and manufacturing
g requirements.
q
Often these rules are
differentiated symbolically. Most people know that = means "equal to" but the symbols
for "less than" and "greater than" can cause confusion.
Here's an easy way to keep them straight:
< The symbol for Less than points to the Left.
Example: 5 < 9 means five is less than nine.
> The symbol for greater than points to the Right
Right.
Example: 9 > 5 means nine is greater than 5.

Before you start this training
Before you start:
You should attach index tabs to the first page of each section of your copy of
the API 1104 to make referencing the sections an easier task, and highlight
significant
i ifi
t tables
t bl and
d figures
fi
that
th t you will
ill use ffrequently.
tl
API 1104 has 13 sections and two appendices (appendix A & appendix B).
During the open book code exam you will have 2 hours to answer 60
questions (2 minutes per question average).
There are three steps to passing the open book code exam:
1. Understand the question
2. Know what section of the Code your answer will be located and
locate it
3. Mark your answer key with the correct answer and be sure not to
skip a question and get out of sync with the list of questions.
Do not guess the answers – look them up in the code.

Table of contents
List of Tables
A table is a arrangement of data in rows and columns
columns.
Tables are listed by number, title, and the page on which they appear in the text.
List of figures
A figure is an illustration of a pictorial nature. Figures are listed by number, title, and the
page on which they appear in the text.
And use your tabs to get to the section you need.

Analyze the question and be sure you understand what is being ask,
then use
a. the table of contents
b. list of figures (images)
c. list of tables ((information listed in tables))
to locate the correct answer.
NOTE:
Not all items are listed in the table of contents / list of figures / list of

Per Section 1 API 1104 provides a list of permitted welding processes, and does not allow 
for  substitutions without formal consideration by the API 1104 Committee.

and nonstandard names for the permitted processes:

Gas metal arc welding (GMAW), also called metal inert gas (MIG) welding.

cored arc welding (FCAW).
Plasma arc welding (PAW).
Oxyacetylene welding (OAW), also called gas welding.
Flash butt welding (FW).
API 1104 also discusses the use of manual, semiautomatic, mechanized, or automatic welding techniques.
For definitions of these techniques, see Section 3 of API 1104.

1104 Code Book – Notes (cont.)
Per Section 1 API 1104 covers procedures and acceptance standards for various kinds of nondestructive
testing.
The following list,
list in the same order as in Section 1
1, gives common industry abbreviations and
nonstandard names:
• Radiographic testing (RT) (x-ray and gamma radiation testing).
• Ultrasonic testing (UT).
• Magnetic particle testing (MT)
(MT).
• Liquid penetrant testing (PT).
• Visual testing (VT).

API 1104 emphasizes that you must use one system or the other, and not combine them.

Section 2 - REFERENCED PUBLICATIONS
Section 2 of API 1104 lists the standards, codes, and specifications referenced throughout the standard.
The footnotes provide contact information
Section 3 - DEFINITION OF TERMS

Welding Terms and Definitions.

4.2 Materials
4.2.1 Pipe and Fittings - API 1104 says that pipe and fittings must conform to API Spec 5L or any applicable ASTM
specifications, but it then states that chemically and mechanically similar materials also are acceptable.
4.2.2.2 Storage and Handling of Filler Metals and Fluxes
API 1104 requires protection of filler metals and fluxes from deterioration and excessive changes in moisture. Lowhydrogen electrodes (classification number ending in 5,6, or 8) must remain moisture- free. Although it is not mentioned in
great detail in API 1104, electrode manufacturers recommend that low hydrogen electrodes be stored in a heated, vented
oven at a prescribed temperature after opening their container.
4.2.3 Shielding Gases
4.2.3.1 Types
By definition, an inert gas does not combine chemically with other materials. An active gas does. Inert gases include argon and helium.
Active gases include carbon dioxide and oxygen. Gases must be pure and dry, and the gas or mixture of gases for a given procedure
must be of welding quality.
4.2.3.2 Storage
g and Handling
g
A crucial prohibition with respect to shielding gases involves field intermixing. Never try to force one kind of gas into a cylinder
containing another or bring gases to the arc in multiple hoses.

Note:
Pay close attention to any foot notes.
Carefully review the tables and figures, being attentive to superscripts and their corresponding
footnotes which can modify the effect of the information in the table or figure.
footnotes,
figure
You will see three types of footnotes:
Global footnote appears at the top of a figure, list, or table, and influences everything therein.
Regional footnote appears at the top of a column, subsection, or row in a figure, list, or table,
and influences only that portion of the material.
Local footnote applies only to the specific item being footnoted
footnoted.
For example, turn to page 8 in your copy of API 1104. Note the small superscript letters that follow
certain Filler Metal Group Numbers in Table 1. Each superscript refers to a footnote, which changes
