This will discuss some of the best ways to prepare for your welding licensing test. There are also provide some tips that will help you score high on the exam. So whether you’re just starting in welding or are looking to renew your license, read on for helpful information.

Are you a welder looking to get your welding license in the United States? If so, then you’ll need to pass a welding licensing test. The certification process can be daunting, but with the right preparation and practice, you can make sure that you’re ready for anything. This guide will go over everything you need to know about the welding licensing test so that you can be confident on test day.

Welding has become an increasingly complex and technical science, which is why the American Welding Society was created. The welding certification test will measure your ability to be a competent industrial metal fabricator by meeting minimum requirements for experience in this field, all while demonstrating that you can pass rigorous exams with ease.

8 Tips To Prepare for a Welding Test

These are some helpful tips for preparing your Welding License Test. Whether you’re an experienced welder or just beginning, these methods will help ensure success.

1. The Welding Categories 

Learn what the six main welding categories you’ll be evaluated on are. Although there are many metal fabrication processes and methods, the AWS certification only covers a few of them.

  • Shielded Metal Arc Welding – SMAW.
  • Gas Tungsten Arc Welding – GTAW.
  • Gas Metal Arc Welding – GMAW.
  • Flux Cored Arc Welding – FCAW.
  • Oxy-fuel Gas Cutting and;
  • Plasma Arc Cutting.

2. Choose one certificate at a time

When you’re looking for a specific welding certification, it can be important to know which one applies for what kind of welding you want to do. There are many federal and state laws in America that regulate building codes as well as rules about how much welding equipment or shielding gas may legally use during certain tasks depending on what kind of work is required by law, some areas require more than others so make sure your research covers all potential requirements before starting any projects.

3. Study and follow all the AWS standards.

To ensure the highest quality work, you should follow all of AWS’s standards (codes and specifications). Fabrication such as metalworking is covered under one specific code for each country where it’s used, so make sure to study up on these carefully.

API -This code specifies the manufacture of low-pressure tanks and piping for transporting and storing fuels and petroleum oil.

ASME – This code covers the same range of metal fabrication processes as AWS, although it is most often used to build pressure vessels and high-pressure piping in the United States.

4. The test plate’s blueprint. 

To pass the AWS D1.1 steel plate groove test, you will need to know how each type of welding works and what materials they are using for it not only to show up on your welds but also prevent them from breaking down when exposed under high pressure or temperature situations which could lead to failure before completion.

5. Thick plate

Welding is a challenging and rewarding career that allows you to use your skills across many industries. The physical demands of welding can be met by completing two difficult positions on the test, as well as one thick steel plate size from 1/8″ up until unlimited thicknesses are available for testing.

6. Practice Diligent

When it comes to welding, the most important thing is that you are practising. The code allows for some errors such as undercut and porosity, but these can be clues about how much experience a welder has had so make sure all of your welds meet industry standards by practising diligently until they’re flawless continuous uniformity across every scope condition possible.

7. Invite a friend to give a reliable critique.

When you’re studying for a welding test, the last thing that will help is having your friends offer excuses instead of helping. Your critical friends can nit-pick away at any mistakes and give suggestions on how to improve them so take advantage.

8. Choose a good quality over the looks.

The destructive testing procedure for sheet metal lays down three conditions: if you welded a thicker plate than 3/8″ then it will be bent with an outward-facing edge on one side of your joint; otherwise, when working on thinner materials two test strips are cut from each piece and these sample pieces are stretched in opposite directions until they break at their strongest points.

Avoiding Common Mistakes to Pass a Welding Test

  1. Don’t go too quickly. To the pace of your welds, match the filler metal feed rate, depth, and thickness.
  2. Incorrect settings on the welder must be corrected. Every instrument you utilize and all parameters for the correct application should be double-checked.
  3.  Improper storage, handling, and usage of welding materials and supplies can all contribute to weld spatter. The electrode in 7018 must be kept in a rod oven to keep moisture out of the flux.
  4.  Clean any debris residue after each pass, taking your time. When leaving flux behind, this is the most typical reason for this to happen. It will not be burned out next pass.
  5. Ensure you achieve fusion on the sides of the weld. Completely infuse the entire joint area. It should be a smooth transition between filler weld metal and base metal.
  6. Carefully review the entire instructions and double-check all of the blueprint’s measurements. Even if you’ve completed the same blueprint before, take your time and cut one section at a time.
  7. The blueprint measurements of the test plate might have been adjusted without notice.
  8. Always use good judgment and follow required safety procedures.
  9. Examine the entire work environment and equipment for electrical connections and any safety hazards, paying particular attention to the electrical system.
  10. Wear appropriate-fitting work clothing to protect your entire body from molten metal, searing heat, sparks, and electric shock.
  11. Use only modest or loose clothing. You’re working in a dangerous environment with moving equipment and power tools, so you could easily be dismembered or burned.
  12. Don’t wear pants, jackets, aprons, or coveralls with exposed pockets, sleeves, or collars. If a 2000-degree molten metal object or spark gets caught in your garment, you could suffer serious burns.

Multiple Choice Questions – Answers

1A – The key is major function, and that is to purify the weld pool and weld metal.
2C – The shape of the output wave form from this type power source is referred to as square wave. These type of power sources have enhanced performance on a.c. They can control the balance, amplitude, frequency, to allow better control of penetration and cleaning action.
3B – The surrounding air around the weld pool, contains oxygen, nitrogen and hydrogen. These gases get into the molten weld pool and cause gas bubbles to form (porosity) and lead to embrittlement and weld cracking.
4D – Weld backing is used on the back side of the joint to prevent melt through and to assure complete penetration of the weld joint.
5C – The density of steel is 490 pounds per cubic foot and its specific gravity is 7.8 times that of water. Water weighs 1000 Kg/m3. Therefore, a cubic meter of steel would weigh approximately 7800 kg depending upon the exact grade of steel being checked. Porosity, slag inclusion or other types of discontinuities would reduce the weight but not the specific gravity.
C –
7B – When welding, the melting point of steel (approx. 27800 F) versus the solidification point of the fast freezing flux or slag (approx. 32000 F)  is important to know. Also, it is important to know that the melting point varies with the carbon and alloy content of steel. Steel is magnetic until heated above the transformation temperature of approximately 1333 0 F. How fast the metal conducts heat will have a large effect of preheat and inter-pass temperature control. How much the metal expands on heating and contracts when cooling needs to be understood to control buckling.
8D – Undercut best describes this fashion. Some people want to call it “under fill” but it is not correct, since it is not in the weld being located next to the toe.
9B – If the weld does not combine with another weld or the base metal it is referred to as Incomplete fusion. Weld defects due to incomplete fusion | Weld Defects | News
10A – WPQR determines if a welder is qualified to a Welding Procedure Specification.
11B – This welding technique would appear in the welding instructions or in the welding procedure specification. This generally increases the heat input per weld pass, but will generally reduce the total number of weld passes required to fill the joint.
12D – A fisheye is caused by the presence of hydrogen in the weld. If this appeared on a break test of some type it may or may not be acceptable. Always verify the acceptance criteria per the code or specification.
13A – This is also considered the operating factor and is thought of as the percentage of a shift that a welder/welding operator is actually welding. For robotic and mechanized welding, it can be as high as 90% while for manual and semiautomatic welding it can be as low as 10-20% operating.
14B – Though the weld symbols are identical, the sequence of how the welds are made is different.  The back weld is made last and the backing weld is made first.
15D – VT stands for Visual Examination. This is the most common NDE process and can be used before, during and after welding to assure product quality and productivity.
D – Capillary action is the ability of a liquid to flow in a narrow space or root opening. This is accomplished without the assistance of external forces and even in opposition of external forces.  
17B – A standard is established for use as a rule or basis of comparison in measuring or judging capacity, quantity, content, extent, value, quality.
18D – All industrial codes and standards reference the requirement for having qualified procedures. They need to be openly available and the welders need to be trained on their proper use. The welders need to be qualified on those procedures and their qualification must be current. The supervisor needs to do this by verifying the welder’s continuity report.
19C – Cotton and wool are generally recommended apparel around welding operations. Synthetics like polyester, rayon, are not recommended as they melt, creating more of burn hazard
C –
