Welding monitor uses pressure on back side of weldment to monitor penetration of weld. Sudden drop on pressure chart means weld pool has fully penetrated; sudden rise means pool no longer extends through joint. Devised to ensure full penetration along full lengths of weld joints, when direct observation of back sides by visual inspection, x rays, or fiber optics not possible. Used in initial development of welding parameters or during production as safeguard.
