In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This Unit Standard will be useful for someone who wishes to complete a NQF Level 2 Learnership (or skills programme) in Saw Doctoring.

People credited with this Unit Standard are able to:
  • Explain the techniques of welding and brazing saw blades using oxygen/acetylene.
  • Use oxygen/acetylene to weld and braze saw blades.
  • Clean the welds after using oxygen/acetylene to weld and braze saw blades. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    A Learner who wishes to enter a learning programme for this Unit Standard must be able to demonstrate:
  • Competence in mathematical and communication skills equivalent to NQF Level 1.
  • An understanding of the basic activities of the lumber milling process.
  • Skills competencies equivalent to NQF Level 1 of Saw Doctoring as required by the NQF Level 1 Learnership. 

  • UNIT STANDARD RANGE 
    The scope of this Unit Standard covers:
  • The whole environmental that can be described as the lumber mill with all the processing equipment.
  • The whole environment including equipment, tools and instruments that can be described as the Saw Doctor Shop in the Lumber Mill.
  • All the personnel involved in all the activities in the Saw Doctor Shop.
  • All the material that is handled and used in this work area, regarding oxygen/acetylene welding and brazing.
  • All relevant procedures to be followed when welding and brazing with oxygen/acetylene.
  • All relevant brazing and welding activities required of a Saw Doctor in a Lumber Mill.
  • All the relevant work procedures and safety, health and environmental management requirements relating to the Saw Doctor Shop.

    The context of this Unit Standard relates to the training of a learner at NQF Level 2 in Saw Doctoring and specifically to use oxygen/acetylene to weld and braze saw blades.

    The level assigned to this Unit Standard, i.e. NQF Level 2, is appropriate because:
  • For foundational competence the learner has to demonstrate basic comprehension and employ a narrow range of skills.
  • For practical competence the learner has to show basic competence in a limited range of established and familiar contexts under general supervision and quality control.
  • For reflexive competence the learner has to demonstrate the ability to handle some limited responsibility for quantity and quality of own output.

    The nature of the tasks performed, the scope of learning involved and the required responsibility levels, are consistent with those generally defined for NQF Level 2.
