Welding jaws (clamping system) for closed wig - orbital welding heads with an integrated heat shield and guide system for the upper clamping jaw pair and an active gas cooling

摘要

Welding jaws (clamping system) for wig - orbital welding heads for the fixing and centering of two pipe ends (parts of a joint), which are made from four parts (a set = four parts) and in the suitable welding head (system binding) by means of a screw connection and / or clamping connection be fastened, characterized in that the shoe halves shaped portions (1) to the welding head center along one or more solid radii. These shaped portions, the effect of the shielding of the remaining welding head system and thus act as heat shield.
