HOW TO USE THIS MODULE
Welcome to the module “SHIELDED METAL ARC WELDING NC 1I”. This
module contains training materials and activities for you to complete. The
unit of competency “Basic, Common and Core Competencies” contains
knowledge, skills and attitudes required for a shielded metal arc welding NC
I course. You are required to go through a series of learning activities in order
to complete each of the learning outcomes of the module. In each learning
outcome there are Information sheets, Operation sheets, Job sheets and
Activity sheets. Follow this activity on your own and answer the Self-check at
the end of each leaning activity.
If you have questions, don’t hesitate to ask your facilitator for

assistance.
Recognition of Prior Learning (RPL)
You may already have some of the knowledge and skills covered in this
module because you have:
 been working for some time
 training related to this area of qualification
 Already have completed training in this area.
If you can demonstrate to your trainer that you are competent in a

particular skill or skills, talk to him/her about having them formally
recognized so you don’t have to do the same training again. If you have a
qualification or Certificate of Competency from previous trainings show it to
your trainer. If the skills you acquired are still current and relevant to this
module, they may become part of the evidence you can present for RPL. If you
are not sure about the currency of your skills, discuss it with your trainer.
Remember to:
Work through all the information and complete the activities
in each section.
Read information sheets and complete the self-check. Suggested
references are included to supplement the materials provided in this module.
Most probably your trainer will also be your supervisor or manager.
He/she is there to support you and show you the correct way to do things.
You will be given plenty of opportunity to ask questions and practice on
the job. Make sure you practice your new skills during regular work shift. This
way you will improve both your speed and memory and also your confidence.
Use the Self-checks, Operation Sheets or Job Sheets at the end of each
section to test your own progress.

After completing this module ask your trainer to assess your
competency. Result of your assessment will be recorded in your competency
profile. All the learning activities are designed for you to complete at your own
pace.
Inside this module you will find the activities for you to complete
followed by relevant information sheets for each learning outcome. Each

Information sheet
1.1-1
Perform root pass
Root pass simply refers to the 1st pass in any weld process, which
makes the two members being welded, one structure. Subsequent passes
increase the weld depth to the desired thickness, yielding the necessary
strength.
The root pass is the first pass on an open joint, usually when welding
pipe and mild steel. It is usually used as a first pass that will provide the
base for subsequent filler passes. Since it is bridging a gap it may be done
with a quick freezing rod with a cellulosic flux like 6010 or 6011. Some of
the root may be ground away to eliminate any voids and laid over with a low
hydrogen rod such as 7018 until the weld is completed.
Perform Root pass

1. Tack the plates on the jig
2. Adjust height of the jig
3. Ground clamp
4. Hand tools needed
5. Materials needed
6. Notify the welding assessor that you are ready to start your root pass
Tips: in performing root pass

 Use E6010 1/8”
 DCEP polarity set up
 Set current at minimum( 1/8” = 90 amperes)
– test arc
 Adjust accordingly depending on your
preference
 Begin at the bottom welding up
 Make sure your stance is comfortable so you
can support yourself while welding
 Make sure you can see the weld puddle
 Maintain a short arc and concentrate on the
root gap
 Ensure root pass penetration
 Point your rod to the center of the pipe to
melt both edges
 Push the rod inside the pipe so the arc is in
the inside when welding
 The sound of the electrode burning should be coming from the inside
of the pipe

SEPTEMBER 2019
Page 9 of 36
 If burn hole occurs, stop weld to prevent it from getting bigger.
 Skip the burn hole, continue weld pass
 Return to the burn hole after cleaning the slag
 Clean the root pass and repair burn holes if there are any.
 Slow down your speed of travel for the root pass, if the keyhole is
large your amperage is too high.
 Adjust amperage accordingly.
 Should arc be broken, grind and clean the slag before you continue
your weldment
 Do not exceed root pass the groove face
 Clean Root Pass
 Grind the root pass until it shines/ clear all the slag
 Maintain the groove line
 Groove face
Root Pass
Widely used in plate and pipe desgns

 Face side is not as important as root surface on bac or inside.
 If root surface is correct: frot side can be ground, gouged or burned out
Weld is evaluated from root side only

 Root face for most grooves will be out the same size

Cleaning root pass
Stringer bead brushes have narrower knots twisted from base to tip, making
them better suited to penetrate tighter spaces like corners, fillets, and root
pass welds during cleaning. Remember, the tips of wire brushes do the work, so
using appropriate pressure is key to performance and efficiency.

well!!!

Perform Capping
The final weld bead in the in a weld joint. It may be completed in the
form of a stringer bead or by waving a motion back and forth.
Perform Capping Pass

 Use 1/8” E7018 DCEP
 Set current setting to 100 amperes
 Feather weld ends when restarting weld beads
 Manipulate electrode from side to side to create a welder bead.
Some basic guidelines for welding the cap are as follows:
 Keep your electrode angle pointed to the center of the groove at all times
with very few exceptions.
 Keep your arc length as short as possible.
 If possible, drag your electrode slightly no matter what the position is. Most
people will disagree with this but it works for me because it keeps the slag
behind the puddle. Once you build a shelf of weld then you can drag.
 Only move forward and side to side with the electrode otherwise the weld
will become rough.
 When the steel plates gets to hot let it cool down or put on a vice grip to lean
on.
 Make sure you fuse the bevels edge by pushing the toe of the weld into it.
 Overlap stringer beads from at least 25% to a maximum of 50%. The goal is
for the weld to have a single flat profile when finished.
