8. Welding Techniques
MIG, TIG, stick, spot—different processes to fuse metals with heat and sometimes pressure, each with its quirks and strengths.
Why It's Important
Strong, clean welds keep structures honest. Bad prep or wrong process, and the joint tells on you later.
How to Improve Welding Techniques Skills
Prep like it matters: Fit-up, bevels, clean surfaces. Most weld quality is decided before the arc starts.
Dial the parameters: Match current, voltage, wire/rod, and shielding gas to material and joint.
Control heat: Manage travel speed and interpass temps to avoid distortion and brittleness.
Follow a WPS: Use a welding procedure specification for repeatability and compliance.
Inspect and learn: Visual checks, fillet gauges, bend tests when needed—then adjust technique.
