Multipass 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.
