WELDER - CITS
For groove welds, use joints that will minimize the volume of weld metal. Consider double-sided joints instead of
single-sided joints.
Weld alternately on either side of the joint when possible with multiple-pass welds.
Use low heat input procedures. This generally means high deposition rates and higher travel speeds.
Use welding positioners to achieve the maximum amount of flat-position welding.
The flat position permits the use of large-diameter electrodes and high- Deposition-rate welding procedures.
Weld toward the unrestrained part of the member.
Use clamps, fixtures, and strong backs to maintain fit up and alignment.
Prebend the members or preset the joints to let shrinkage pull them back into alignment.
Sequence subassemblies and final assemblies so that the welds being made
Continually balance each other around the neutral axis of the section.
