23
Global
?
!

• America
• Companies responsible for workers safty
• Over-exaggerating very safe look
• Asia
• Companies choose equipment of the welder
• Clean, with a high level of technology
• Europe
• Workers choose their own r.p.u
• Appreciate innovative design and ergonomics

24
Legislation
?
!

• NEN CE norms
• Air flow gt120 l /min.
• pressure in helmet lt7 mbar.
• duration of batteries gt4 h.
• noise of the device lt75 dB.
• thread for apparatus M45x3.
• Recommended voltage lt60 V (D.C.) or lt25
  V (A.C.)
• Hoses and couplings gt(500 ?50)N applied
  axially for (10?1)s.
• Total mass lt5 kg
• Weight on the head lt1,5 kg

25
Problem Definition
?
!

• Safety
• Indication when the filters have to be replaced.
• After welding it should be possible to remove the
  headpiece, but to keep the respiratory protection
  on.
• No parts of the r.p.u. should stick out of the
  back of the welder.

26
Problem Definition
?
!

• Ergonomics
• Easy replacement of the filters.
• Indication of full filters
• Low level of noise (lt 75db).
• Vibrations from the motor should not reach the
  welder.
• The airflow should not cause discomforts while
  being used.
• The r.p.u. should not limit the sight on the work
  piece.

27
Problem Definition
?
!

• Technique/adequate performance
• The inside of the unit should be protected
  against dust and small particles, to increase
  lifetime of the motor
• The weight of the battery should become less then
  1/3 of the present battery
• The welding sparks should not affect the r.p.u.

28
Problem Definition
?
!

• Global Design
• The r.p.u. should have a uniform look, in stead
  of just a combination of different parts.
• The r.p.u. should look conform the preference of
  American, Asian or European market.

29
Problem Definition
?
!

• Financial advantage
• Where possible use of standard products
• Avoid complex design of the non-standard parts
• As few parts as possible, avoid screws
• Finding a compromise between costs of dismantling
  and lowest possible costs of the R.P.U

Life cycle analysis of the models with Tornado

?
!
35
Conclusions LCA

?
!
From the end-of-life comparison of the two models
with Tornado, we can see that

• The two models have similar financial lines,
• The disassembly time of the two models is much
  shorter with respect to that of Tornado,
• The total cost/profit cumulative of the two
  models is much lower with respect to that of
  Tornado.

These characteristics are very important since in
the near future, producers will have more
responsibilities about the treatment of their
end-of-life products.
36
Conclusions LCA

?
!
From the life cycle comparison of the two models
with Tornado, we can see that

• The two models have similar environmental effects
  (MET points) lines,
• The total environmental effects of the two models
  is worse with respect to that of Tornado,
• The difference is more significant at the
  production stage,
• There is a potential for improvement by focusing
  on types of materials (thermoplastics), weights
  of parts and manufacturing processes,
• The end-of-life destinations associated to
  disassembled parts are compliant with legislation
  even if they have negative environmental effects.

With respect to the priorities of the near
future globalisation, lower end-of-life costs
and compliance with legislation on environment,
we can consider that the developed models are
quite satisfactory.
