It has been nearly a quarter of a century since researchers first conceived of combining a conventional welding arc with a laser beam in a hybrid process but only recently has lasergas metal arc GMA hybrid welding begun to be utilized in industrial applications. Now, hybrid laser-GMA welding is fast making the transition from laboratory to production, in industries as diverse as shipbuilding to automobile manufacturing. Recent work investigating the potential benefit of applying this technology to a shipyard pipe shop suggests that significant cost savings may be realized. This paper presents ongoing efforts to study and evaluate hybrid welding, and to estimate potential cost savings that may be realized in a shipyard pipe welding shop.
