Gas Metal Arc Welding (MIG) Questions and Answers Graded A+ Why is the arc in MIG welding often referred to as a "continuous spark"? Because the electrode wire is fed continuously, maintaining a steady arc without breaks during welding. How does changing the shielding gas mix affect the MIG weld quality? Different gas mixes, like CO2 or Argon, can alter weld penetration, bead appearance, and spatter levels. Why is it important to maintain the correct electrode stickout in M...

MIG Welding Questions and Answers Already Passed What is the primary function of the shielding gas in MIG welding? The shielding gas protects the weld from atmospheric contamination, ensuring a clean weld pool. How does the wire feed speed impact the MIG welding process? The wire feed speed controls the amount of filler metal, influencing weld penetration and bead size. What type of polarity is commonly used in MIG welding? Direct Current Electrode Positive (DCEP) is commonly us...

MIG and TIG Welding Test Questions and Answers Rated A+ How does the diameter of the tungsten electrode affect the welding process? Larger diameter tungsten allows for higher amperage and deeper penetration, while smaller diameters are better for thinner materials. What is the significance of cleaning the base metal before welding? Cleaning removes contaminants such as rust, oil, and dirt, which can lead to weak welds or defects. What is a common indication of poor gas coverage i...

Extremely detailed revision notes for the migration, identity and sovereignty topic in paper 2 for A Level Edexcel Geography. I included most things listed on the specification and achieved an A* in A Level Geography using these notes. A few aspects are missing from the spec for this specific topic as I missed out what I didn’t need as my exams were in 2022 and had advanced information (should only be enquiry q 4)
