MIG Welding Techniques and Projects Guide

Apr 25, 2025

MIG Welding Tutorial

Equipment and Setup

  • Welder: Dual voltage MIG welder
  • Power Source: Plugged into 115V on a 20 amp breaker
  • Material: Cold rolled steel, no cleaning required
  • Settings:
    • Voltage: 18 volts
    • Wire Feed Speed: 196 inches/min with 0.035 wire

Welding Projects

  1. Outside Corner Joint

    • Experiment with lower settings
    • Aim for a MIG-like TIG look with ripples
    • Plan to perform cut and edge test for penetration
  2. Uphill Fillet Weld

    • Increase wire feed speed slightly to 212 inches/min
    • Clean nozzle before welding with MIG pliers (welpers)

Techniques

  • Corner Joint:

    • Keep arc on the leading edge of the puddle
    • Maintain short stick out length (affects amperage)
    • Focus on flowing metal into the root of the joint
  • Uphill Fillet Weld:

    • Use upside down "V" technique to ensure penetration
    • Technique places arc on leading edge to avoid cold lap or lack of fusion
    • Avoid reducing settings for aesthetic purposes; prioritize penetration

Testing and Results

  • Cut and Etch Test:
    • Reveals weld penetration and potential lack of fusion
    • Conduct test with a polish and etchant

Personal Insights and Advice

  • Video Production:
    • First video posted 15 years ago with low-resolution camera
    • Emphasizes starting where you are and committing to improvement
    • Importance of taking action rather than waiting for ideal conditions

Conclusion

  • Key takeaway is to start with available resources and commit to continuous improvement. This approach enabled the creation of over 600 videos on welding.
