Can anyone help??? This was due yesterday??? This is welding!
If the questions aren't clear then here they are.

1.) The step motion (we call it the stitch motion), is used with what type of welding electrodes?
2.) What type of penetration is gained by using the step motion technique?
3.) A vertical weld can be made in which directions?
4.) Which vertical technique is the easiest to perform?
5.) What technique or motion is used when welding in the horizontal position?
6.) 6013 electrodes were designed to weld; what material, in what polarity, while traveling in what direction?
7.) What is the recommended amperage to be used when welding a ⅛” 6013 electrode in AC?
8.) If you make a small weld, what can be done to correct this problem according to the video?
9.) What solidifies first when welding with 7018, the poodle or the flux?
10.) What is porosity?
11.) What can cause porosity?
12.) When using a ⅛” 7018 electrode in DC+, when is the suggested amperage?

Answer:

1.

2.black box

3. Weld left to right or right to left, make sure the contact tip is within ⅜” of the work when welding, meaning that there should never be more than ⅜” of wire “sticking out”, tilt the handle to about 75 degrees.

4. Vertical jump technique

5. For the horizontal position welding technique, you need to point the MIG gun upward in an angle between 35-45 degrees and tilted at an angle between 15-35 degrees towards the weld position.

6. The 6013 electrodes can be used with AC or DC (either straight or reverse polarity) in any position. It can weld mild steel to medium steel. However, there are some positive and negative reviews about the E6013. It has a thicker coating, for example, that does not spatter.

10. Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%.

11. Porosity is caused by the absorption of nitrogen, oxygen and hydrogen in the molten weld pool which is then released on solidification to become trapped in the weld metal.

12. When using a 3/32-inch diameter rod is that you will need to use 50 amps on 1/16-inch steel thickness and around 90 amps on the ⅛-inch thickness of steel. You will need to set the amps much higher for the bigger rods. For 5/32-inch diameter rod, you can set the current at 120 amps for welding the 1/4-inch steel.
