Fabrication and Welding
Fabrication
Cutting: Use appropriate cutting methods such as sawing or shearing to achieve the desired tube lengths. Avoid excessive heat input to prevent material distortion.
Forming: Cold forming techniques such as bending and rolling may be employed to shape the tubes. Ensure that the forming process does not compromise the integrity of the tubes.
Machining: If machining is required, use sharp tools and appropriate cutting speeds to minimize work hardening and achieve dimensional accuracy.
Cleaning: Remove any contaminants or surface impurities from the tubes before further processing or welding.
Welding
Preparation: Ensure proper fit-up and joint preparation to achieve full penetration and minimize distortion. Beveling or chamfering may be necessary for thicker tubes.
Welding Method: Use welding methods such as Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), or Shielded Metal Arc Welding (SMAW) suitable for the material and application.
Consumables: Select welding consumables, including electrodes and filler metals, compatible with the base material to ensure weld integrity and mechanical properties.
Welding Parameters: Control welding parameters such as heat input, travel speed, and interpass temperature to minimize the risk of distortion, cracking, and metallurgical changes.
Post-Weld Treatment: Perform post-weld heat treatment as necessary to relieve residual stresses and restore material properties. This may include annealing, stress relieving, or solution heat treatment.
Inspection: Conduct thorough visual inspection and non-destructive testing (NDT) to detect weld defects such as cracks, porosity, or incomplete fusion. Follow relevant codes and standards for inspection procedures.
