Enclosed Weld Heads

Enclosed Weld Heads provide complete inert gas protection of the full weld bead circumference (an industry requirement for producing welded joints in electro-polished and hygienic applications). Collets are required for each tube diameter to be welded.

‘Fusion’ applications only, filler wire cannot be used with these heads. Welding will be made after preparation of the tube ends to provide a flat, square face. During welding the weld head remains static, only the rotor carrying the electrode rotates in an ‘orbital’ motion around the tube.

Our range of OSK weld heads are unique in design, the cable and handle/motor assembly is separate from the weld head itself, so one handle assembly can run a variety of different sized weld heads. This concept provides significant cost savings on multiple weld head systems and unmatched flexibility using the same weld heads on different manufacturers´ power supplies.

Four versions of the OSK welds are available:

Compact Gas Cooled, Gas Cooled, Water Cooled and High Duty Water Cooled
