ultipass welds used in oil and gas pipeline construction are critical since weld failure can be catastrophic. In addition to being subject to stringent quality requirements, pipeline construction is often completed in challenging environments. Due to tight project timelines and the need to ensure proper penetration between weld passes, operators and helpers typically must grind and clean the welds while they are still hot. All these factors make proper weld preparation and interpass cleaning crucial to the success of the overall process. Knowing the common mistakes to avoid and which abrasive products can help get the work done is important to maintaining quality and staying on production timelines.
Pipeline welding challenges As mentioned above, the sometimes-difficult environment and stringent quality and timeline demands of pipeline welding introduce challenges into weld preparation and cleaning. In midstream pipeline construction, full-length pipe is often laid out in the right-of-way (ROW) already bevelled. The pipe gang preps the pipe by cleaning the rust and pits off of this bevel. They then face the land to a nickel thickness and tack weld the
