A system and method is provided in which a welding system modulates the heat input into a weld joint during welding by changing between a high heat input welding waveform and a low heat input welding waveform. The system can utilize detected weld joint geometry and thickness to vary the utilization of the high heat and low heat waveform portions to change the weld bead profile during welding. Additionally, the wire feed speed is changed with the changes between the high heat input and low heat input portions of the welding waveform.

Apparatus and method for modulating heat input during welding

A welding fixture and method allow for both coarse and fine adjustments of headstocks and tailstocks for securing a tank or other cylindrical-like object within a welding fixture. Coarse adjustment is provided by adjusting the headstock and/or tailstock linearly along a rail system. Find adjustment is provided by linearly adjusting a movable table on which the headstock and/or tailstock rest. The headstock and tailstock may also have compression clamping members for securing the tank to the headstock and tailstock. Pipe stands are also provided for supporting the tank before, during, and after the welding process.
