The purpose of the course ”Welding of stainless steel” is to provide technicians, engineers and chief engineers of projection, operation and maintenance a skills enhancement on optimisation of welded structures and components of stainless steel.

Participants

Technicians, foremen and other supervisors
Skilled workers, in need of extra training
Engineers

The course is directed at construction, development and production people, and users and personnel dealing with quality control.

Target

The participants will be supplied with state of the art knowledge of relevant welding methods and their impact on corrosion and mechanical properties.

Content

The course focuses on welding of stainless steel viewed from a materials’ point.

The materials are supplied from the works in a condition, in which it has been striven to achieve the best combination of properties as regards corrosion and strength.

In connection with welding, a change of the material in the heat affected zone is introduced. A new element in the form of weld metal or braze is added, which has a deviating structured and perhaps also deviating composition. Furthermore, the geometry and state of stress have been changed.

Special conditions as regards defects in the joints and methods for test will be reviewed. The training is based on an oral presentation in close cooperation with the participants.

The course is not a work-shop course, and thus practical problems and solutions will be presented in examples, assignments and demonstrations.

The following subject shall be dealt with:

  • The processes’ special properties as regards as regards heat treatment, metallurgical treatment, geometry and properties of strength.
  • The processes, TIG (GTAW)-, MIG (GMAW)-, laser-, resistance and plasma welding will be dealt with: brief description of the solid state  processes (friction and fusion welding)
  • Brazing processes: heat impact, corrosion problems and soldering brittleness
  • Welding metallurgy: hardening, Microstructure, phase transformation, secondary precipitation and material combinations
  • Choice of filler materials and welding without fillers (autogeneous)
  • The impact of shielding gases such as arc gas and purge/backing gas
  • Heat treatment
  • The welded joint’s impact on corrosion: constructive shape, strength and welding defects
  • Post treatment of surfaces
  • Control of the welded joint
  • Micro structure control
  • Corrosion testing
  • Various examples and exercises.
