Abstract: A pipeline padding machine is disclosed. The pipeline padding machine includes a machine main frame, a cabin coupled to the machine main frame and an extension mechanism. The extension mechanism can couple the cabin to the machine main frame. The extension mechanism can be configured to translate the cabin vertically relative to the machine main frame. Because the extension mechanism can translate the cabin vertically, the pipeline padding machine can allow for improved operator access and improved operating positions. Alternatively, or additionally, the cabin may be horizontally translated and/or rotated about a vertical axis.

Abstract: A backing plate for includes a synthetic diamond portion configured to abut a joint region during a welding operation. A welding clamp includes a plurality of clamping blocks, each including a synthetic diamond portion configured to abut a pipe joint region during a welding operation. Because the backing plate and clamping block each include a synthetic diamond portion, the backing plate and clamping block can withstand high welding temperatures without damaging or diminishing the quality of the weld.

Abstract: A method is disclosed. The method includes disposing an automated welding device adjacent to a pipe joint and welding an open root pass via the automated welding device using the predefined welding process, wherein the predefined welding process is configured to control a welding arc in response to a short circuit condition. A secondary welding process can be overlaid on the predefined welding process by cycling welding parameter of the predefined welding process can be cycled between a high parameter value and a low parameter value about a base parameter value. Further, an arc between the automated welding device and the pipe joint can be maintained during welding. Because the welding parameter is cycled between a high and low parameter value, the automated welding device can deliver consistent successful welds.
