Joints can be a variousdesigns depending on

thickness and results required. Plates should be Clean, free

from grease, oil and excessivescale.

SAW is the standard process

used on the AGW, an openarc process can also be usedwith modifications to thewelding equipment.

Joint Design and PreparationAll Joint Designs and Welding Procedures discussed are

rough starting references. All Joints and procedures must be

qualified by the end user or tank manufacturer.

Welding ConsumablesThe mechanical properties obtained from actual production

joints may vary considerably from those obtained on the test

data shown below.

For Welding Carbon and HighStrength Low Alloy SteelsSelecting the proper fillercombinations for submerged arc

welding is slightly more

complicated than for other

processes because there are two

distinct components: Flux and

Electrode. Both flux and

electrode determine mechanicalproperties.

Most Sample procedures areperformed with Lincoln 780 Flux, L-60and L-61 Wire.

780 flux characteristics, include very good slag removal, making it the

most common choice for a variety of applications. The faster freezing

of 780 slag minimizes spilling on roundabouts. Low flash-through

with excellent bead shape and slag removal make 780/L-60 excellent

for semiautomatic welding.

Basic Set-up Steps before welding

1) Set Flux Belt to Joint2) Adjust Head Angle

3) Set Electrode Stick-out

4) Position Electrode (6mm) from weld Joint (vertical/horizontal adj.)

5) Manually drop flux to cover Weld

6) Set Travel Speed, Volts and Amps for plate thickness

7) Switch Flux recovery vacuum on

8) Begin weld, maintaining proper Parameters
