Certified Robotic Arc Welding (CRAW) study plan

Map the robot program structure used in arc welding cells (main routine, subroutines, job/step hierarchy) and write a one-page diagram of your controller's execution model

Define and contrast joint, world, tool, and user frames, then state in writing which frame each of three common welding motions should be taught in and why

Identify the six axes of a typical arc welding robot and label each axis's motion type (rotational or translational) on a hand-drawn sketch

Explain the difference between a linear move, a joint-interpolated move, and a circular move, and give one welding scenario where each is the correct choice

Set up a practice program that moves the tool through five taught points using at least two motion types, and describe the resulting path shape in your notes

Write and run a program that uses at least one conditional branch and one loop, and record the logic flow in pseudocode

Implement a search or touch-sense routine and explain how the offset it produces is applied to a taught weld path

Describe how weave patterns (sine, triangular, circular) affect bead width and sidewall fusion, and configure two patterns with stated amplitude and frequency

Explain the roles of start, end, and crater conditions in a welding procedure and match each to the correct program instruction

Trace one fault from a program logic error versus one from a process parameter error and state the diagnostic step that distinguishes them

Compare short-circuit, globular, spray, and pulsed transfer in writing, listing current range, droplet behavior, and positional suitability for each

Select shielding gas mixtures for carbon steel, stainless steel, and aluminum, and justify each choice by transfer mode and spatter tendency

Set wire feed speed, voltage, and travel speed for a flat fillet and a vertical-up fillet, and record the resulting arc characteristics

Identify each component of a GMAW torch and wire feeder setup (contact tip, liner, drive rolls, gas solenoid) and state one failure symptom for each

Explain the effect of contact-tip-to-work distance and torch angle on penetration and bead profile, and demonstrate two deliberately wrong settings

List the hazards of arc welding (arc radiation, fume, spatter, electric shock, fire) and the control for each, without consulting notes

Explain the purpose and correct use of a welding helmet shade selection chart across at least four process and current combinations

Describe a lockout/tagout sequence for servicing a robot cell and identify the energy sources that must be isolated

Explain why the robot work envelope must be restricted and how safeguarding devices (light curtains, interlocks, fences) enforce it

State the fume extraction and ventilation requirements for confined-space and open-area welding and describe one monitoring method

Define essential variables for a welding procedure specification and list which changes require requalification

Write a procedure qualification record outline for a groove weld, naming the tests that would be performed

Define the standard terms for joint types, weld types, and weld positions and use them correctly in a written description of a test coupon

Explain the difference between preheat, interpass temperature, and post-weld heat treatment, and state how each is verified

Match a given base metal and thickness to an appropriate procedure and justify the choice of process, filler, and position

Describe visual examination acceptance criteria for undercut, porosity, and overlap, and apply them to a set of sample weld photographs or coupons

Explain radiographic and ultrasonic examination principles and state one strength and one limitation of each

Explain penetrant and magnetic particle testing, and select the correct method for a given material and defect type

Describe tensile, bend, impact, and hardness tests and state what each reveals about a weld

Interpret a set of sample test results and determine whether the weld meets a stated criterion

Read and reproduce welding symbols including fillet, groove, and weld-all-around, and place the arrow and tail correctly

Explain how welding symbols are used in robot programming documentation to define path and joint intent

Identify the components of an arc welding robot cell (robot arm, positioner, power source, wire feeder, torch, safety enclosure) and state each component's function

Convert between inches and millimeters, and between amperage, wire feed speed, and deposition rate using standard formulas

Calculate heat input from voltage, current, and travel speed, and state the units and the effect of travel speed on the result

Integrate program logic, process parameters, and examination criteria in a written end-to-end cell operating scenario

Complete a timed practice set across all twelve domains and score it, then list the three weakest areas

Re-explain the three weakest areas from memory in writing and correct any errors against source material

Review every prior deliverable and rewrite any section that is incomplete or inaccurate

State your exam-day plan including time allocation per domain based on weighting
