  2. Weld access hole - Wikipedia

    en.wikipedia.org/wiki/Weld_access_hole

    Without the weld access hole, the middle of the flange would be blocked by the web and inaccessible for welding. The hole also minimizes the induction of thermal stresses with a combination of partially releasing the welded section, avoiding welding the T section where the flange joins the web and improving cooling conditions.

  3. 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.

  4. List of welding codes - Wikipedia

    en.wikipedia.org/wiki/List_of_welding_codes

    Specification and qualification of welding procedures for metallic materials - General rules ISO/TR 15608: Welding - Guidelines for a metallic material grouping system ISO 15609: Specification and qualification of welding procedures for metallic materials - Welding procedure specification, five parts. ISO 15610

  5. Welding Procedure Specification - Wikipedia

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

    The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...

  6. 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 ]

  7. Magnetic particle inspection - Wikipedia

    en.wikipedia.org/wiki/Magnetic_particle_inspection

    Magnetic yoke is a hand-held device that induces a magnetic field between two poles. Common applications are for outdoor use, remote locations, and weld inspection. The drawback of magnetic yokes is that they only induce a magnetic field between the poles, so large-scale inspections using the device can be time-consuming.

  8. Welding - Wikipedia

    en.wikipedia.org/wiki/Welding

    For manual welding methods, labor costs generally make up the vast majority of the total cost. As a result, many cost-saving measures are focused on minimizing operation time. To do this, welding procedures with high deposition rates can be selected, and weld parameters can be fine-tuned to increase welding speed.

  9. Welder certification - Wikipedia

    en.wikipedia.org/wiki/Welder_certification

    In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.
