  2. Symbols and conventions used in welding documentation

    en.wikipedia.org/wiki/Symbols_and_conventions...

    The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.

  3. List of welding processes - Wikipedia

    en.wikipedia.org/wiki/List_of_welding_processes

    This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

  4. Welding Procedure Specification - Wikipedia

    en.wikipedia.org/wiki/Welding_Procedure...

    Bend test coupons for welding procedure qualification. A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements.

  5. Autogenous welding - Wikipedia

    en.wikipedia.org/wiki/Autogenous_welding

    Autogenous welding is a form of welding in which the filler material is either supplied by melting the base material or is of identical composition. [1] The weld may be formed entirely by melting parts of the base metal, and no additional filler rod is used. There is some variation in the use of this term.

  6. Ultrasonic welding - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_welding

    Milk and juice containers are examples of products often sealed using ultrasonic welding. The paper parts to be sealed are coated with plastic, generally polypropylene or polyethylene, and then welded together to create an airtight seal. [17] The main obstacle to overcome in this process is the setting of the parameters.

  7. Welding joint - Wikipedia

    en.wikipedia.org/wiki/Welding_joint

    Pipes and tubing can be made from rolling and welding together strips, sheets, or plates of material. [4] Flare-groove joints are used for welding metals that, because of their shape, form a convenient groove for welding, such as a pipe against a flat surface. Selection of the right weld joint depends on the thickness and process used.

  8. Weld access hole - Wikipedia

    en.wikipedia.org/wiki/Weld_access_hole

    The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam. The hole in the web allows a welder to weld the flange to another part of the structure with a continuous weld the full width on both top and bottom sides of the flange.

  9. Electric resistance welding - Wikipedia

    en.wikipedia.org/wiki/Electric_resistance_welding

    Seam welding has been used to manufacture steel beverage cans but is no longer used for this as modern beverage cans are seamless aluminum. There are two modes for seam welding: Intermittent and continuous. In intermittent seam welding, the wheels advance to the desired position and stop to make each weld.
