Ahaa, där ser man.
Hade en gammal tråd i bakhuvudet där det diskuterades att det kunde bli kinkigt om man ville ha en svetsad rattstång godkänd.
Brukar det vara lätt att få ut material och rekommenderat tillsatsmaterial eller svetstråd från knut-tillverkare och dylikt? Kan ju vara bra att veta när dagen kommer:-)

12L14
Description: This grade is essentially 1215, a resulphurized, rephosporized, low carbon steel in which lead has been added.

Uses: It maximizes machinability. It is used for bushings, inserts, couplings, etc. It has good ductility and is suitable for parts involving bending, crimping, or riveting.

Heat Treating Characteristics: Not recommended.

Weldability: Due to very high sulphur and lead content, welding is not recommended.

3 Reasons To Not Weld Free Machining Steels
http://pmpaspeakingofprecision.com/2009/08/25/3-reasons-to-not-weld-fr . . . .

Any type of arc welding of resulfurized steels is generally avoided. This post will give you some reasons why. Resulfurized steels are free machining steels. This includes steel grades in the 11XX and 12XX series, such as 1215, 12L14, 1117, 1137, and 1144. These steels contain sulfur and may contain lead. These two elements will create low melting temperature constituents that will cause cracks.

Here are 3 reasons not to weld resulfurized free machining steels:

Sulfur reduces weldability. The higher levels of sulfur make a slaggy joint.
The high volume fraction of manganese sulfides also hold hydrogen. This hydrogen can then create post weld cracking.
Both sulfur and lead can become a fume inhalation hazard at welding temperature.
