Claims7
A pipe welding apparatus, comprising:
- a support fixed to the ground;
- a torch which is supported by the support and is formed to correspond to a welding portion of a pipe;
- a first rotation part for rotating the torch in a circumferential direction of the pipe up to a predetermined angle;
- and
- a second rotation part for rotating the torch in an axial direction of the pipe up to a predetermined angle,
- wherein the first rotation part comprises an outer bracket which performs a horizontal reciprocating motion along a guide provided at the support and an inner bracket which is hinge-connected to the outer bracket around a rotating axis, and
- wherein the second rotation part comprises:
- a fixing member attached to the support;
- a second rotation part connecting member for connecting the torch and the fixing member;
- a screw fixation member connected to the fixing member;
- a central member which becomes a center of rotation;
- and a second rotation part bolt which is formed to passing through the fixing member and the screw fixation member and provides a welding force so that the fixing member rotates around the central member.
