1.

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

Pitanje 2
2.

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

Pitanje 3
3.

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

Pitanje 4
4.

When Welding, you can wear synthetic clothing.

Pitanje 5
5.

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

Pitanje 6
6.

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

Pitanje 7
7.

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

Pitanje 8
8.

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

9.

Arc Welding is better know as Stick Welding

Pitanje 10
10.

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

Pitanje 11
11.

Slag is only found on a ARC weld.

Pitanje 12
12.

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

Pitanje 13
13.

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

Pitanje 14
14.

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

Pitanje 15

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

Pitanje 16

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

Pitanje 17

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

Pitanje 18

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

Pitanje 19

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

Pitanje 20

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

Pitanje 21
21.

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

Pitanje 22

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

Pitanje 23

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

Pitanje 24
24.

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

Pitanje 25
25.

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.
