Welding process energy consumption detection method

1 Scope

GB/T 43656-2024 gives the methods for measuring the energy a welding operation consumes. Welding is one of the larger electricity loads in Chinese manufacturing and one of the least measured, because the consumption of a single machine varies with the process, the duty cycle, the idle time and the auxiliary equipment, and because there has been no agreed unit against which to compare a resistance welder with a laser welder. The standard fixes that by defining the energy consumption per unit of weld - per unit length, area or joint according to the process - and the conversion factors that make the processes comparable. It sets the general requirements, the requirements on the measuring equipment, the scope and types of energy consumption to be counted, the detection and calculation methods, and the test report, with informative annexes giving the conversion factors for pressure welding, friction welding and brazing units and worked calculation examples for laser wire welding and induction brazing. It took effect on 1 July 2024.

This document specifies the general requirements for energy consumption testing during the processing of welding methods such as fusion welding, pressure welding and brazing, as well as the requirements for testing instruments. Requirements, energy consumption test scope and types, test and calculation methods and test reports. This document is applicable to the detection of energy consumption during the processing (including no-load and welding) of welding methods such as fusion welding, pressure welding and brazing. The welding method can be implemented as a reference. The energy consumption test does not include the energy consumed by preheating before welding and heat treatment after welding.
