How do changes in weld parameters affect a weld?

Scenario: A baseline weld was made using automated welding equipment. Voltage, wire feed speed, travel speed and contact-tip-to-work distance were then adjusted individually from baseline weld settings to illustrate how each parameter affects a fillet weld when raised and lowered. See the results in this simple breakdown.
