25.160 - Welding, brazing and soldering

This document specifies the performance requirements for fluxes in solid, liquid and paste forms
intended for use with soft solders.
NOTE 1 ISO 9454-1 specifies the requirements for labelling and packaging as well as the coding system for the
classification of the fluxes.
NOTE 2 Some of the fluxes intended for inert gas and vapour phase soldering may not pass some of the criteria
in Tables 1 and 2.
Requirements for these fluxes are agreed between the purchaser and the supplier.

The principle of the method specified is to distil a prepared flux solution with sodium hydroxide to expel the ammonia present in the flux, to pass the resulting distillate into a standard sulfuric acid solution, to titrate the excess acid with sodium hydroxide solution and to calculate the ammonia content of the flux. Applies to fluxes of class 3.1.1 only, as defined in ISO 9454-1.

This document specifies a qualitative method for assessing the aggressiveness of a flux towards copper.
The test is applicable to all fluxes of type 1 as defined in ISO 9454-1.

This document outlines the equipment and operator qualification needed for laser-arc hybrid welding, and recommends butt, fillet and flange joint preparations and consumables suitable for use with this process. It also gives an overview of the steps to take during equipment set-up, procedure specification, workpiece set-up immediately prior to welding, and after welding once inspecting and testing the welds. This document applies to laser-arc hybrid welding of steels, aluminium and its alloys. T...view more
