Axon Engineering offers a variety of welding options. In-house welding is performed in our specially designed, designated welding area.

We are certified by TÜV Hellas – TÜV Nord for groove butt welding according to Section IX ASME Boiler and Pressure Vessel Code. Axon is certified for Procedure Qualification Record (PQR) , Welding Procedure Specification (WPS) and two operators obtained Welder Operator Qualification Tests Records (WQTR) for ASTM A240 Grade 304, EN10025-2 Grade S275J0+N and DIN EN 10083-3 Grade 42CrMo4.

Also Axon is certified by EuroCert for fillet welding, for Welding Procedure Specification (WPS) according to EN 15609-1, for Welding Procedure Qualification Records (WPQR) according to EN ISO15614-1:2011 and Welders Qualification Test Certificate (WPQ) according to EN ISO9603-1:2013.


A common and cost effective coating process, phosphating is a crystalline conversion coating formed on ferrous metals, achieved by means of emersion. This process is commonly used to amplify corrosion protection properties, increase friction properties of sliding parts and finally enhance adhesion of surfaces to be painted.

Phosphate Characteristics 

Appearance Dark Grey to Black 
Additional Coating Oil or Paint
Standards BS EN 12476 
Coating Thickness +0.005 mm

Black oxide

A chemical conversion coating that does not alter mechanical, physical or dimensional characteristics of the treated surface. Its application, contrary to other conversion coatings available, is mostly decorative as it offers a restricted corrosion protection in mild conditions, proving to be an excellent cost effective solution.

Black Oxide Characteristics 

Appearance Uniform black 
Referred Standard MIL- DTL-13924 D
Coating Thickness  None

Chromate conversion coating (Alodine 1200S)

Alodine is a chemical conversion coating for aluminum and aluminum alloys. The treated surface appears to have increased anti-corrosion properties and an improved bond for painting.

Alodine 1200S Characteristics 

Appearance Light iridescent golden to tan
Referred Standard MIL –DTL-5541
Coating Thickness None
