Pre-established WPs
The pre-established WPs (Welding Procedures) have
been developed by the Polysoude laboratory to allow
a fast approach to customised procedures. These WPs
correspond to frequently faced applications. Search
criteria are the name of the WP, the tube diameter,
the wall thickness, the base material, the application,
the type of welding head, the weld position; the P6
power source can offer you the pre-defi ned WP best
suited to the request. You are then able to modify
this user WP to refi ne the welding procedure.
All WPs are intended to be executed with argon as
shielding gas.
Warning: Some applications require
two or more programs.
All programs that use fi ller wire have been developed
with wire of 0.8 mm diameter.
The result and the quality of a weld is infl uenced
considerably by non-programmable adjustments. In
the pre-defi ned WPs you will fi nd the values chosen
as each program was generated. The parameters
are:
