Tips For Not Destroying Your Welds While Inspecting Them

The most frustrating thing about testing weld security is that the most common method for testing welds is to see how much force you can apply on either side in order to break it. This means that you have to clean off the area of the old weld parts and then redo the weld every time you perform a test. Here are some tips for testing your welds without destroying them and forcing you to redo them.

1. Visual Inspection

The first thing that you want to do is perform a visual inspection. This is the most cost-effective method of examining welds and although is not the most thorough, it will help you identify a lot of problems before they even have a chance to occur. You should perform a visual inspection of the welding machinery before the welding process is performed in order to see if there are any problems with the equipment that could affect how strong the welds are. The materials that are going to be involved in the welding process should also be inspected to make sure that there are no problems with them. The process of welding should be watched by someone who knows what the ideal form should be at the end. Just by visually inspecting the welding process from start to finish, you can spot a lot of problems without ever having to undo the weld.

2. Radiographic Inspection

The next type of inspection that you can do is radiographic inspection, which uses x-rays to inspect the weld. Certain opaque materials will absorb the x-rays whereas gaps will allow it through. This is a good way for you to make sure that your weld is entirely solid and leaves no gaps between the materials that you are trying to join. If you see a lot of light or other discrepancies on the radiography output film, then you will want to make sure that you redo the weld because it is not strong enough. If you don't see any of these discrepancies, then you don't need to worry about it. Radiography is a mark of weld quality, however the outputs can be difficult to interpret sometimes. Make sure that you get a few engineers trained on welding in order to make sure that everything is ready to go, or have the welds tested by an independent company.
