AWS Certified Welder study plan

AWS Certified Welder · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Specific welding process & Base material

  • List the four domain weights and rank them by study priority, then allocate weekly hours so that domains 1 and 3 receive at least 60 percent of total time.

  • Define the specific welding process named in the exam scope and diagram its power source, electrode, shielding method, and typical current ranges from memory.

  • Classify at least eight base materials into carbon steel, stainless steel, and aluminum groups and record the matching filler metal or electrode family for each.

  • Identify the three most common process-to-material mismatches and write one corrective rule for each.

Your checkpoint

A one-page process-and-material matrix covering at least eight base materials with the correct filler or electrode family and the process variables that change for each.

Week 2

Specific welding process & Base material

  • Explain how current type, polarity, and amperage affect penetration and deposit rate for the exam process, and predict the outcome of reversing polarity on a given setup.

  • Describe the purpose and adjustment range of the key process variables: voltage, travel speed, wire feed speed or electrode feed, and shielding gas flow.

  • Match preheat and post-weld heat treatment requirements to at least five base materials and thickness ranges.

  • Diagnose five common weld defects (porosity, lack of fusion, undercut, slag inclusion, cracking) and trace each to a likely process or material cause.

Your checkpoint

A defect-cause table listing five defects, the process or material variable most likely responsible, and the parameter adjustment that corrects it.

Week 3

Welding position (flat, horizontal, vertical, overhead) & Joint / pipe diameter configuration

  • Define flat, horizontal, vertical, and overhead positions using the standard position numbering system and sketch the electrode or torch angle for each.

  • Select the correct position designation for at least six described joint setups, including pipe fixed and pipe rotated conditions.

  • Compare heat input and deposition control strategies across the four positions and state which position demands the lowest heat input and why.

  • Identify the joint types (butt, lap, tee, corner, edge) and the standard groove preparations associated with each.

Your checkpoint

A position-and-joint reference sheet with four position sketches, correct numbering, and the joint type and groove preparation for each of six setups.

Week 4

Welding position (flat, horizontal, vertical, overhead) & Joint / pipe diameter configuration

  • Calculate the number of test coupons or passes required for a given pipe diameter and wall thickness using the standard qualification rules.

  • Explain how pipe diameter and wall thickness change the qualified thickness range and position qualification for a welder.

  • Describe the difference between fixed-pipe and rolled-pipe testing and predict which positions are qualified by each.

  • Outline the sequence of root, fill, and cap passes for a fixed-pipe joint and state the inspection point after each stage.

Your checkpoint

A worked qualification scenario showing a chosen pipe diameter, wall thickness, and position, the resulting qualified range, and a pass-by-pass inspection checklist.

Week 5

Specific welding process & Welding position (flat, horizontal, vertical, overhead)

  • Practice setting process parameters for each of the four positions and record the amperage, voltage, and travel speed that produce an acceptable bead in each.

  • Explain why vertical and overhead positions require lower current or different manipulation than flat and horizontal, and state the consequence of using flat-position settings overhead.

  • Identify the manipulation techniques (stringer, weave, whip, step) appropriate to each position and the limits on weave width.

  • Correlate three common position-specific defects with the process variable that causes them.

Your checkpoint

A position-parameter log with one recorded setting set and one identified risk per position, plus the corrective adjustment for each risk.

Week 6

Base material & Joint / pipe diameter configuration

  • Match at least six base-material and joint-thickness combinations to the required preheat, interpass temperature, and filler selection.

  • Explain how base material chemistry (carbon equivalent, alloy content) influences cracking risk in restrained joints and what controls mitigate it.

  • Describe joint fit-up tolerances (root gap, land, misalignment) and predict the effect of each on penetration and defect formation.

  • Compare qualification requirements for plate versus pipe and state which variables are essential and which are nonessential.

Your checkpoint

A material-joint compatibility chart covering six combinations with preheat, interpass limit, filler, and the fit-up tolerance most critical to each.

Week 7

Specific welding process & Welding position (flat, horizontal, vertical, overhead) & Base material & Joint / pipe diameter configuration

  • Complete a timed 40-question mixed practice set spanning all four domains and score each answer by domain to expose weak areas.

  • Re-teach the two lowest-scoring domain topics from memory in written form without notes, then correct errors against source material.

  • Build a flashcard set of at least 30 facts covering process variables, position numbering, material groups, and joint qualification rules.

  • Resolve every missed practice question by writing the correct reasoning and the distractor logic that made the wrong answer plausible.

Your checkpoint

A scored 40-question practice log with per-domain accuracy percentages and written corrections for every missed item.

Week 8

Specific welding process & Welding position (flat, horizontal, vertical, overhead) & Base material & Joint / pipe diameter configuration

  • Complete two full-length timed mock exams under test conditions and compare per-domain scores against the week 4 milestone.

  • Review only the highest-frequency missed concepts and confirm mastery by explaining each aloud in under one minute.

  • Rehearse the exam-day routine: position numbering recall, process-variable checklist, and material-group decision tree.

  • Finalize a one-page summary sheet of formulas, position codes, and qualification rules for last-minute review.

Your checkpoint

Two completed timed mock exams with score reports showing at least 80 percent overall and no domain below 70 percent, plus a final one-page summary sheet.

Milestones

Week 2: Score at least 75 percent on a 20-question quiz limited to domains 1 and 3, and correctly complete the process-and-material matrix without notes.

Week 4: Correctly assign position designations and qualification ranges for at least eight of ten described joint and pipe setups, and produce an accurate worked qualification scenario.

Week 6: Score at least 75 percent on a 30-question mixed quiz covering domains 3 and 4, and complete the material-joint compatibility chart with no more than one error.

Week 8: Achieve at least 80 percent overall on two timed full-length mock exams with no single domain below 70 percent, and finish the one-page summary sheet.
