![]() If the shape is located on the bottom side of the reference line, that means the weld should be applied on the same side of the joint as the arrow is located. ![]() These symbols indicate what type of weld should be performed on the joint. In the middle of the line, there will always be a shape such as a triangle, a V or parallel lines for example. The reference line is the heart of the information on a welding blueprint. ![]() The leader line is simply the line that connects the arrow with the horizontal reference line. Each arrow will lead to a set of instructions and we’ll talk about that below. Unless you have a set of basic blueprints, your document will probably have a number or arrows on it pointing to multiple different areas that need to be welded. The arrow points to the area on the blueprint where the weld should be applied. Image credit: Pinterest The Arrow & Leader Line The diagram may seem a little busy, but it does a good job of covering the fundamentals of welding blueprint reading. In the image below you’ll notice a depiction of a horizontal line with an arrow angling downward at the end of the line. We’re going to review some of the more common symbols and how they’re used so that you can use this document as a great starting point. There are tons of them and that’s why we suggested earlier to keep reference material around the workplace. So now that we know which points of view blueprints can be drawn from the next step is to become more familiar with the various symbols drawn on a welding blueprint. The top view looks like an aerial view if you were standing over the object and the right-side view shows the object or objects from the perspective on the right side. ![]() There’s no trick language here – the front view shows a picture of the object to be welded from the front of the object. If there’s one area of understanding welding blueprints that doesn’t require a lot of explanation, it’s this section. First, let’s take a look at the view or perspective you can expect to find on welding blueprints. It doesn’t matter whether you choose to offer blueprint training in-house, seek outside help or if you decide to take on the training roll yourself – the fundamentals of how to read blueprints for welding remain the same. The 3 Basic Views Or Perspective Found In Welding Blueprints A simple way to get around this is to make sure that your workplace has reference books, a collection of accessible videos and strategically located posters to help a staff welder track down a symbol that they’re not familiar with. Workplace Posters, Videos & LiteratureĮven welders that can read blueprints may not have all welding blueprint symbols memorized – that shouldn’t come as much of a surprise as there are many of them. The solution is to bring in outside help when needed or to offer incentives and help for welders to take welding blueprint courses to further career goals and to help the company grow. It’s always a good idea to help employees with training to make them better at their job. That doesn’t mean you shouldn’t help your staff welders fill in any gaps that they may have when it comes to reading blueprints. Option 2: Outside Helpįor a small business, hiring a dedicated trainer may not make a lot of financial sense. When taking advantage of an in-house trainer you can help your employees to upgrade their skills whenever time permits without having to compromise your business schedule. Having an in-house trainer is a great idea if you employ a significant number of welders. If you’re the owner of a medium to large-sized business with a focus on the welding industry or if you have a division with a welding shop its always a good idea to consider your options for helping your staff welders increase their knowledge and skills.
