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.
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 ...
The ASME developed its boiler code in 1915. The code provided a solid reference of construction standards, but ASME lacked the authority to regulate. This was further complicated by the existence of local and state jurisdictions with their own codes and standards. This resulted in a patchwork of confusion having no basis in consistency.
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 ]
The largest ASME standard, both in size and in the number of volunteers involved in its preparation, is the ASME Boiler and Pressure Vessel Code (BPVC). The BPVC provides rules for the design, fabrication, installation, inspection, care, and use of boilers, pressure vessels, and nuclear components. The code also includes standards on materials ...
Heat traps are very simple and inexpensive. They are an effective way to prevent cooling of hot water in water heaters by thermosyphoning the hot water to a higher elevated portion of the piping system. Thermosyphoning is based on natural convection. Hot water rises and is then displaced by cold water beneath it. The heat trap stops this ...
