What preparations should a welder take before touching an arc?

2021-10-27

The work done before the first arc is drawn will have a huge impact on the scope of the project and the integrity of the metal. Whether it is from the production of project plans and organization of materials, or from the inspection and cleaning of materials, these preparations should be completed before the start of welding.

For a manufacturing workshop, it is very necessary to ensure that all preparations are completed before the welding process starts. In the end, if you fail to take the necessary initial steps when the project is conceived, it may end up in vain, leaving a costly mistake.

Preparation before welding

Preparation before welding is as important as the welding process itself, because it is related to the success of your project. Therefore, before starting a welding project, please consider the following measures:

1. Check the materials. 

First, you must inspect the material to look for defects, such as scratches or grooves, and determine whether your material and size are correct items. You should also check to make sure the material is clean, square, and if there are holes and grooves. Inspection can also confirm that appropriate materials are present and organized correctly. This is one of the most important steps because it sets the tone for the entire project and eliminates any unpredictable problems in the material.

2. Review project details and drawings.

 This is where you can start to visualize how to assemble the structure. This step also allows the team to gather all the necessary materials, tools, and equipment to effectively build the project. If this is a component you have not welded before, practice welding a piece of scrap metal to help eliminate errors and shorten the duration of the project. This will allow you to dial in device or machine settings in advance. The more customized and unique the project, the longer this step will take, but the more important it becomes to optimize the entire project.

3. Organize your materials and equipment. 

Taking the time to place materials in a strategic location can reduce errors and enable the team to find what is needed immediately.

4. Assess the potential safety hazards in the area. 

Any existing security issues need to be checked and resolved quickly and effectively. Removing unsafe or unnecessary equipment and materials can provide you and your team with a safe and clean working space to carry out projects. The goal of your store should be to increase efficiency while maintaining top quality in a safe environment.

Visual inspection

Checking your materials and equipment is more important and necessary than you may realize. The inspection phase allows you to polish up the problems in the process, erase anything that might contaminate the welding, and consolidate your overall plan.

The inspection process can be a thorough or brief inspection according to your needs. It can be as simple as checking the material type to determine whether it is steel or aluminum, or lifting and touching the material to determine its weight, which will help identify the material. For more complex materials, the magnet can determine whether the material is mild steel or stainless steel, because stainless steel is not magnetic.

When you visually inspect materials, be sure to search for contaminants. If found, wipe the material with a towel or wire brush to remove any remaining dirt. If oil stains are present, you may need to use chemical cleaners to remove it. Since metal is porous, oil will be absorbed, causing serious setbacks and damage to the project. If oil is found on the material, you can use denatured alcohol to remove it. In extreme cases, methyl ethyl ketone (MEK) is required. MEK is a dangerous chemical substance that needs to be handled very carefully due to its flammability. It should be stored in a plunger container to prevent fumes from escaping.

When inspecting materials used in production, it is important to check their verticality and proper dimensions. The end square will provide a more compatible match, which in turn will result in higher quality welds, less delay, and improved structural integrity. If there are air pockets or debris in the welds, it will depend on the strength of these welds. If the material is not inspected in advance, the structural integrity of the weld will be weakened. Determining the right size is as simple as pulling a tape measure on it. However, if the tolerance is very tight, a micrometer may be required.

As you begin to examine project details and drawings in a broader way, assigning color codes to different parts of the project can provide a clearer picture and help organize your thoughts. The organization may take some time in the beginning, but in the end it will save time and possibly prevent any mistakes. You might consider positioning all the materials you will use in the same direction to ensure a fast and organized project area.

Checking whether personal protective equipment is damaged, and checking whether there is a possibility of fire or electrical hazards in the workplace are essential to creating a safe working environment. In addition, the use of proper weightlifting techniques is essential to prevent injuries. Thinking ahead of time how to transport the structure out of the work area or prepare it for transport will lead to a smoother project.

detail

Make sure to review every detail of your welding work to make the process as efficient as possible.

Proper preparation before welding can improve efficiency, reduce errors, and reduce the risk of injury. Taking appropriate steps at the beginning can speed up the run time during production. Having a proper plan is the key to completing a successful project, ensuring consistency and a better quality insurance plan.

Although it is not necessary to take preparatory measures before starting a welding project, it is recommended. This will improve the entire manufacturing process. When you use clean, well-prepared materials, the structural integrity of the materials may not be compromised. Taking these necessary steps at the beginning of this process can result in a more cost-effective strategy. Preparing for the first arc can only improve the process and effect of the weld.
