Extensive work in research has resulted in the development of a wide range of alloys and welding procedures.

Because many common welding procedures involve an open electric arc or flame, the risk of burns is significant.

Cracks developed in the oil bath casing due to incorrect welding procedure.

His job was to teach safe quality welding procedures, not-foment union demands, or whatever this conversation was sliding toward.

Electric Boat said, however, that since the cracks had been discovered, welding procedures had been revised to eliminate the problem.

It must descend, expand, climb, perform complicated welding procedures by remote control and cut steel like butter.

Elaborate welding procedures may be used to achieve the highest quality repairs.

Many basic welding procedures are done by hand, rather than by robot (there are only two in the plant).

The welding procedure qualification test piece replicates all of the essential variables that will be used in production welding.

Electric Boat said that it had revised its welding procedures to eliminate the problem, but a Pentagon spokesman called the cracks "extremely serious."
