instructions

Information:

The following welding instructions are for information only. In general,

the relevant welding regulations must be noted. The AD leaﬂets must

also be noted when welding on pressure vessels.

When welding stainless steel, utmost cleanness is necessary. E.g. it is

not allowed to use rusty tools or screwed parts. Also make sure that no

mild steel is processed in the closer environment.

Use enought inert gase for tack-welding. Make sure that you use tack-

welding and not spot-welding. For tack-welding and welding, the

protective gas pure argon must be used.

The suitable welding dummy must be used to avoid the distortion of

the welded socket.
