Automated welding techniques using robotic welders and large positioners have greatly increased the quality of industrial welding. Greater reliability can be provided using automated welding techniques. In addition, the welds can be completed rapidly, without the use of highly paid and highly skilled welders.
In addition, the use of positioners to position a piece for welding has also provided for high quality welds. Welds that are performed when the piece is disposed in a horizontal position allow the weld to properly flow into an opening and properly fill the space in the opening. Large positioners are capable of rotating large pieces into positions, so that horizontal, high quality welds can be performed.
