Meeting #545 Agenda for October 12, 2021

Agenda

Helpful Hint

The number one failure of a MIG weld is porosity. The most common cause of porosity is welding a dirty, oily, painted surface. All these contaminants get trapped in the weld, resulting in holes that resemble a sponge.

Lincoln Electric’s Karl Hoes says a welding arc requires a smooth flow of electricity through a complete electrical circuit. Welding current will seek the path of least resistance. So if care is not taken to place the welding ground close to the arc, the current may find another pathway. Firmly attach the clamp to bare metal as close as possible to the arc.

As a general rule, keep the distance the wire sticks out from the end of the gun’s contact tip to between 1/4 and 3∕8 inch.

“Use both hands whenever possible,” Collier urges. “Rest the crook of the gun neck in one hand and hold the part with the trigger in the other hand. Don’t hesitate when it comes to having your prop hand close to the weld. Get a heat-resistant, heavy welding glove if you need it.”
