Fabrication techniques encompass the methods, processes, and practices used to transform raw materials into finished equipment. Mastery of core techniques—welding, machining, forming, assembly—combined with specialized methods enables fabricators to produce diverse equipment types and meet varied specifications.

Welding techniques include SMAW (stick), GMAW (MIG), GTAW (TIG), FCAW, and SAW, each suited to different materials, positions, and applications. Advanced techniques like orbital welding for consistent root passes, narrow-gap welding for thick materials, and overlay welding for corrosion resistance extend fabrication capabilities.

Machining techniques range from conventional turning and milling to CNC multi-axis machining for complex geometries. Forming techniques include rolling for cylindrical shells, pressing for heads and cones, and specialized forming for unusual shapes. Assembly techniques integrate components using welding, bolting, and specialized connection methods.

Quality techniques ensure technique application meets requirements: weld procedure qualification, machining setup verification, forming dimensional control, and process documentation. Technique selection considers material properties, code requirements, available equipment, and workforce skills.
