Lesson 8.9 Welding

1

Arc Welding is the process that used the heat from an electric arc to join pieces of metal together

1

Safey and Health Risk for Arc and MIG Welding include Electric Shock, Burn, Fire, Breathing Hazards.

1

To help with Electric Shock, make sure everything is properly installed and way from water.

1

When Welding, you can wear synthetic clothing.

1

When welding, your hair can be down and you can wear sunglasses.

1

After finishing each weld, you should dip your work in water and be careful about the steam.

1

To make sure others are blinded, everyone should say "COVER" before starting to weld.

1

Make sure all of the ventilation systems are turned off before starting to weld.

1

Arc Welding is better know as Stick Welding

1

Shielded is the cloud of gases formed by the burning of the flux.

1

Slag is only found on a ARC weld.

1

When welding with a Arc Welder, it is easier to weld in the DC setting.

1

Before your welder will work, the ground clam must be attached.

1

Electrodes are made of 2 parts: Rod and Flux Covering.

1

To have a clean weld, you should Bevel the metal before welding a joint.

1

Striking is EASY. You can either use the scratch or tapping method.

1

While a stringer bead is simple, it takes time to master the straight forward movement.

1

Weave beads that move from side to side, allow you to fix issues along the way.

1

If your travel speed is too FAST, you will have narrow ripples.

1

If your amperage is too LOW, you will have Narrow and Built Up

1

If the Lenth of the Arc is too LONG, you will have Build Up and Poor Penetration.

1

The 4 types of joint welds you will need to make include Butt, Tee, Corner, and Lap.

1

MIG Welding is the process in which a continuous solid wire electrode is fed through a welding gun and into the weld pool, joining the two base materials together

1

When MIG Welding, it is best to use a Gas mixer of 75% argon and 25% carbon dioxide

1

When MIG Welding, just guess on the settings. Don't reference the chart.

When Overhead Welding, be sure to travel at a slow speed for the best weld.
