Welding consumables - Gases and gas mixtures for fusion welding and allied processes (ISO 14175:2008)

This International Standard specifies requirements for the classification of gases and gas mixtures used in fusion welding and allied processes including, but not limited to: - tungsten arc welding (Process 141); - gas-shielded metal arc welding (Process 13); - plasma arc welding (Process 15); - plasma arc cutting (Process 83); - laser welding (Process 52); - laser cutting (Process 84); - arc braze welding (Process 972). The purpose of this International Standard is to classify and designate shielding, backing, process and assist gases in accordance with their chemical properties and metallurgical behaviour as the basis for correct selection by the user and to simplify the possible qualification procedures. Gas purities and mixing tolerances are specified as delivered by the supplier (manufacturer) and not at the point of use. Gases or gas mixtures may be supplied in either liquid or gaseous form, but when used for welding and allied processes, the gases are always used in the gaseous form. Fuel gases, such as acetylene, natural gas, propane, etc., and resonator gases, as used in gas lasers, are not covered by this International Standard. Transportation and handling of gases and containers shall be in accordance with local, national and regional standards and regulations as required.

Schweißzusätze - Gase und Mischgase für das Lichtbogenschweißen und verwandte Prozesse (ISO 14175:2008)

Diese Norm legt Anforderungen für die Einteilung von Gasen und Mischgasen fest, die zum Verbindungs¬schweißen und für verwandte Prozesse verwendet werden; sie sind jedoch nicht auf folgende Anwendungsgebiete begrenzt:
-   Wolfram-Inertgasschweißen (Prozess 141 nach ISO 4063);
-   Metall-Schutzgasschweißen (Prozess 13 nach ISO 4063), was umfasst:
-   Metall-Inertgasschweißen (Prozess 131),
-   Metall-Aktivgasschweißen (Prozess 135),
-   Metall-Aktivgasschweißen mit Fülldrahtelektrode (Prozess 136),
-   Metall-Inertgasschweißen mit Fülldrahtelektrode (Prozess 137);
-   Plasmaschweißen (Prozess 15 nach ISO 4063),
-   Plasmaschneiden (Prozess 83 nach ISO 4063),
-   Laserstrahlschweißen (Prozess 52 nach ISO 4063),
-   Laserstrahlschneiden (Prozess 84 nach ISO 4063),
-   Schweißlöten (Prozess 972 nach ISO 4063).
Es ist der Zweck dieser Norm, Schutzgase, Gase zum Unternahtschutz, Prozessgase und Hilfsgase nach ihren chemischen Eigenschaften und ihrem metallurgischen Verhalten als Grundlage für eine korrekte Auswahl durch den Anwender einzuteilen und zu bezeichnen und für mögliche Zulassungsverfahren zu vereinfachen.
Gasreinheiten und Mischgenauigkeiten gelten für den Anlieferungszustand durch den Lieferant (Hersteller) und nicht für den Zeitpunkt des Verbrauchs.
Gase und Mischgase können entweder in flüssigem oder gasförmigem Zustand geliefert werden; zum Schweißen und für verwandte Prozesse werden die Gase jedoch immer gasförmig verwendet.
Brenngase wie Azetylen, Erdgas, Propan usw. und Lasergase (Resonatorgase) werden von dieser Norm nicht erfasst.
Transport und Gebrauch der Gase und der Gasbehälter müssen nach den vorgeschriebenen örtlichen, nationalen und regionalen Normen und Verordnungen erfolgen.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 14175 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee

SC 3, Welding consumables.

This second edition cancels and replaces the first edition (ISO 14175:1997) which has been technically

revised.

Requests for official interpretations of any aspect of this International Standard should be directed to the

Secretariat of ISO/TC 44/SC 3 via your national standards body, a complete listing of which can be found at

⎯ plasma arc cutting (Process 83);
⎯ laser welding (Process 52);
⎯ laser cutting (Process 84);
⎯ arc braze welding (Process 972).
NOTE Process numbers are in accordance with ISO 4063.

The purpose of this International Standard is to classify and designate shielding, backing, process and assist

gases in accordance with their chemical properties and metallurgical behaviour as the basis for correct

selection by the user and to simplify the possible qualification procedures.

Gas purities and mixing tolerances are specified as delivered by the supplier (manufacturer) and not at the

point of use.

Gases or gas mixtures may be supplied in either liquid or gaseous form, but when used for welding and allied

processes, the gases are always used in the gaseous form.
