Elements and Performance Criteria

Materials
Ferrous and non-ferrous

Heating
Oxy acetylene and fuel gas, cylinders, connections, hoses, tips and nozzles

Consumables
Fluxes (resin or powder), all types of silver solder and brazing grades, etc.

Overview of assessment requirements
A person who demonstrates competency in this unit must be able to perform brazing and silver soldering.

Context of assessment
This unit may be assessed on the job, off the job or a combination of both. Where assessment occurs off the job, i.e. the candidate is not in productive work, then appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

Interdependent assessment
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with brazing and/or silver soldering or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Consistency of performance
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Required skills

Look for evidence that confirms skills in:

preparing materials
performing brazing/silver soldering
undertaking visual inspection
reading and interpreting routine information on written job instructions, specifications and standard operating procedures
following oral instructions

Required knowledge

Look for evidence that confirms knowledge of:

the reasons for selecting specific methods of assembly/alignment
the procedures for minimising distortion of the materials being brazed/silver soldered
the procedures for assembling and setting up the specific heating equipment
the reasons for selecting specific heating equipment
the reasons for selecting specific consumables
conducting test runs
typical applications of brazing and silver soldering processes
the procedures and precautions for preheating the materials to be joined
the effects of the use of inappropriate techniques on the performance of the jointed materials
the effect of inappropriate quantities of jointing material on the performance of the jointed materials
the procedures for normalising the temperature of jointed materials
the consequences of using inappropriate techniques to normalise the temperature of the joint
the procedures for removing excess jointing material
the procedures for inspecting brazed/silver soldered joints
use and application of personal protective equipment for silver soldering and brazing
