    Specification and qualification of welding procedures for metallic materials - Welding procedure test, 13 parts. ISO 15615: Gas welding equipment. Acetylene manifold systems for welding, cutting and allied processes. Safety requirements in high-pressure devices ISO 15618-1: Qualification testing of welders for under-water welding.

  3. Post weld heat treatment - Wikipedia

    en.wikipedia.org/wiki/Post_weld_heat_treatment

    Industry codes, such as the ASME Pressure Vessel and Piping Codes, often require mandatory performance of PWHT on certain materials to ensure a safe design with optimal mechanical and metallurgical properties. [2] [3] The need for PWHT is mostly due to the residual stresses and micro-structural changes that occur after welding has been ...

  4. 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 ...

    en.wikipedia.org/wiki/Weld_quality_assurance

    Weld mapping is the process of assigning information to a weld repair or joint to enable easy identification of weld processes, production (welders, their qualifications, date welded), quality (visual inspection, NDT, standards and specifications) and traceability (tracking weld joints and welded castings, the origin of weld materials).

    The BPVC was created in response to public outcry after several serious explosions in the state of Massachusetts.A fire-tube boiler exploded at the Grover Shoe Factory in Brockton, Massachusetts, on March 20, 1905, which resulted in the deaths of 58 people and injured 150.

  9. Orbital welding - Wikipedia

    en.wikipedia.org/wiki/Orbital_welding

    The main components of the typical orbital welding system are the power supply with integrated computer control, the welding head, and either a wire feed mechanism or a presharpened tungsten electrode. Welding of certain sizes and material types will also require a water/coolant system.
