Automatic orbital welding machine

PLC-controlledfor integrationfor pipes

Product Overview
Automatic outer prop welding machine welds the base plate to the pipe and threaded sleeve without separate joints, providing repeatable dimensional accuracy for prop assemblies. The unit is designed to operate as part of a system with inner prop and base jack welding machines; typical components used in combination include: Base jack welding machine, Inner prop welding machine, Outer prop welding machine, Cup lock welding machine, Ring lock welding machine.

Process and Control
The system performs circular welding on the base plate-to-pipe and pipe-to-threaded-sleeve joints from both positions (top side or inside the sleeve) to maximize throughput and uniform weld quality. Design features reduce operator exposure to spatter and heat during continuous welding. Electrical input is normally 380–415 V, 50–60 Hz; control is via LED interface with a Siemens PLC and motor drive. Clamping and de-clamping of the workpiece and movement of the welding torches are pneumatically operated.
