PRACTICES SMAW 01

Technique:  assemble and tack weld two pieces of 1 ¼ angle six inches long as shown above and run welds in the position of the practice until the angle is completely full of weld on all sides.

PRACTICES SMAW 02

Technique: Set the Amperage on DCRP 130 to 150 and using E-7018 Electrodes place a weld between the joint. Hold the Electrode 90 degrees to the joint as shown above. Change angle of Electrode slightly to overlap next weld beads evenly until the joint is full of weld.

Once the arc is struck the electrode may lightly touch the metal or a slight arc length may be maintained.

Slag each weld bead before applying the next.

Travel from left to right on all weld beads first, and then practice alternating direction.

FOR ALL SMAW PRACTICES

BURN ALL ELECTRODES DOWN AS LOW AS POSSIBLE

PRACTICES SMAW 03

Technique: set the Amperage and weld the first bead using the angles shown above. Adjust the angle slightly to overlap the first bead with the second and third weld beads.

Continue to weld beads from the bottom up overlapping each bead in half until the joint is filled.

Watch for the weld puddle to split the center of the bead under it to keep it straight and for proper placement.

PRACTICES SMAW 04

Technique: Set the Amperage on DCRP 90 to 110 and using E-6010 Electrodes place a weld between the joint. Hold the Electrode 90 degrees to the joint as shown above. Change angle of Electrode slightly to overlap next weld beads evenly until the joint is full of weld.

Once the arc is struck the electrode may lightly touch the metal or a slight arc length may be maintained.

Slag each weld bead before applying the next.

Travel from left to right on all weld beads first, and then practice alternating direction.

Notice the difference in the appearance between the E-7018 Electrode and the E6010 Electrode. While the 7018 produces a thicker smoother weld bead with a heavy slag and medium penetration, the 6010 produces a flatter weld bead with pronounced ripples thinner slag and deep penetration.

PRACTICES SMAW 05

Technique: set the Amperage and weld the first bead using the angles shown above. Adjust the angle slightly to overlap the first bead with the second and third weld beads.

Continue to weld beads from the bottom up overlapping each bead in half until the joint is filled.

Watch for the weld puddle to split the center of the bead under it to keep it straight and for proper placement.

The resulting weld bead is flatter with more pronounced ripples than those produced with the E-7018 electrode. The E-7018 electrodes have iron powder added to the electrode covering (Flux). The iron powder and metal available from the core of these electrode accounts for the heavier, smoother weld bead.

The E-6010 electrode provides a hotter arc that cuts through dirty, rusty, or painted surfaces and produces a weld with a flatter profile, lighter slag covering and deep penetration.

PRACTICES SMAW O6

Technique: Set the welding Amperage on DCRP 100-110 and starting at the top of the joint, hold the correct travel angle, start the arc, and weld down the joint. 

There should be no side to side or weave technique used and the weld bead should be about the size of the electrode including the flux.

Change the angle slightly to overlap a series of weld beads from one side of the joint to the other. Completely fill each side of the angle assembly.

PRACTICES SMAW 07

Technique: set the welding machine for DCRP at 90-110 amps and weld vertical upwards from the bottom of the joint to the top using the weave technique.

The vertical up weave is similar to the vertical up stringers except each pass is weaved from side to side and completely covers the prior weld bead.

The initial amperage (or heat) setting may need to be increased slightly when weaving wider than the first three passes.

Pause in each corner to allow proper filling and weld formation. The weld appearance will be flat with a pronounced ripples.

PRACTICES SMAW 08

Technique: Set the correct amperage on the machine and weld from the bottom of the T joint to the top.

Use a slight weave from side to side as you move up the joint. The closer the weave pattern the better.

The weld bead width should be approximately 1 ½ times the diameter of the electrode.

Place the second and third weld beads as shown above, keeping them the same size and allowing them to overlap half of the prior weld bead.

The side to side weave shown should be quick enough to produce a bead of the proper width, without being too high in the center. Pause slightly in each corner of the weave pattern similar to the motion of a windshield wiper. 

Fill each side of the angle assembly flush with weld beads.

PRACTICES SMAW 09

Technique: set the welding machine for DCRP at 125-150 amps and weld vertical upwards from the bottom of the joint to the top using the weave technique.

The vertical up weave is similar to the vertical up stringers except each pass is weaved from side to side and completely covers the prior weld bead.

The initial amperage (or heat) setting may need to be increased slightly when weaving wider than the first three passes.

Pause in each corner to allow proper filling and weld formation. The weld appearance will be flat to slightly round with a smooth appearance.

PRACTICES SMAW 10

Technique: Set the welding machine on DCRP 90-100 amps for E-6010 electrodes. Weld the assembled angle joint in the overhead position using E-6010 Electrodes. Hold the electrode as indicated and weld from one end of the joint to the other. A slight push or drag method may be used.

In the Overhead position maintain travel speeds that result in a weld bead that is flat and well formed. Slow travel speeds result in a large bead being deposited at is difficult to overlap and blend in. Travel speeds that are too fast result in a thin stringy bead with little penetration.

Continue to run stringer beads until the entire angle is filled with weld.

PRACTICES SMAW 11

Technique: Set the welding machine on DCRP 125-150 amps for E-7018 electrodes. Weld the assembled angle joint in the overhead position using E-7018 Electrodes. Hold the electrode as indicated and weld from one end of the joint to the other. A slight push or drag method may be used.

In the Overhead position maintain travel speeds that result in a weld bead that is flat and well formed. Slow travel speeds result in a large bead being deposited at is difficult to overlap and blend in. Travel speeds that are too fast result in a thin stringy bead with little penetration.

Continue to run stringer beads until the entire angle is filled with weld.

PRACTICES SMAW 12

Technique: The Instructor will use the track burner to cut beveled plates then cut a backing bar for assembling the groove.

The student will remove burning slag and grind the groove face for welding.

The instructor will assist you in aligning and assembling the groove joint and setting it in the welding position.

Remember: we add two more beveled pieces to make 3 welded joints before discarding

PRACTICES SMAW 13

Technique: Place the groove in the flat position and weld the root pass against the backing bar, then continue welding stringers until the joint is filled. The cover passes should not exceed 1/8 inch high or be more than 1/8 over each side of the groove.

PRACTICES SMAW 14

Technique: Place the groove in the Horizontal position and weld the root pass against the backing bar, then continue welding stringers until the joint is filled. The cover passes should not exceed 1/8 inch high or be more than 1/8 over each side of the groove.

PRACTICES SMAW 15

Technique: Place the groove weld in the Vertical up position and weld the first pass against the backing strip using the side to side weave motion. Slag and continue weld passes until joint is filled flush. The final cover pass should not be more than 1/8 inch high and not more than 1/8 inch over the edge of the groove.

PRACTICES SMAW 16

Technique: Place the groove in the Overhead position and weld the root pass against the backing bar, then continue welding stringers until the joint is filled. The cover passes should not exceed 1/8 inch high or be more than 1/8 over each side of the groove.
