I keep getting porosity when welding aluminium. Any …
When welding aluminium by the MIG process, turbulence can occur if too low a welding current is used because large droplets are transferred across the arc. However, excessive currents deposit metal over a gas bubble before it escapes, giving irregular shaped porosity.
How to Weld: The Ultimate Guide - Welding Headquarters
2020/8/2· Depending on the type of welding being done, welders may go for a MIG welder or the multipurpose welder that works for all four types. Apart from having the right machine, welders must be equipped with a welding helmet that will keep their face (especially their eyes) safe from the heat, the gases emitted during the process, and any splattered of the liquid slag.

5 Best MIG Welders - Aug. 2020 - BestReviews
Strictly speaking, this is called flux-cored arc welding (FCAW), but it''s generally seen as one of the two methods of MIG welding. Somewhat confusingly, there are two types of flux wire: gas-shielded flux core wire (which still needs a gas supply as above) and self-shielded flux core wire (in which the flux burns, releasing its own protective gas).

My MIG welder tips page
Common MIG welding is also referred to as short circuit transfer. Metal is deposited only when the wire actually touches the work. No metal is transferred across the arc. Another method of MIG welding, spray transfer moves a stream of tiny molten droplets across
MIG Versus TIG | Articles | Grassroots Motorsports
Since the wire feeds automatically and the heat gets in the weld joint faster, MIG welding is generally a timesaver. We usually figure that MIG welding is about two to three times faster—that is, it will take two to three times as long to lay a 12-inch bead with TIG than MIG.

Why is there no amperage control on a MIG welding …
MIG welding power sources have what is known as a ''constant voltage'' output characteristic (Fig. 1). The arc voltage is established by setting the output voltage on the power supply. The power source will then supply sufficient welding current to melt the welding electrode at the rate required to maintain the preset voltage (or relative arc length).
