A device for welding may include a track configured to surround a workpiece. The device for welding may also include a cart configured to contact the track such that the track guides the cart around the workpiece. The cart may include a frame and a welding torch receptacle. The welding torch receptacle can be attached to the frame. The welding torch receptacle may be configured to maintain a tip of the welding torch at a set distance away from the workpiece while the cart moves around the workpiece.

A method and system for capturing and aligning a drill pipe of a surface drill includes a first arm assembly and a second arm assembly. Each arm assembly features an end effector coupled to a position adjustment mechanism configured to receive a plurality of shims for positional adjustments relative to the drill pipe. The end effectors include ramp features and elongate fingers forming ends of the effectors. The arm assemblies are arranged at an obtuse angle to each other, creating a receptacle for the drill pipe. The method includes positioning the arm assemblies on a mast, actuating them upward and inward, engaging the drill pipe with the elongate fingers, guiding the drill pipe along the ramp features, and capturing the drill pipe in the receptacle formed by the end effectors.
