Welding remains one of the most popular ways of joining metals. As a result it is a fabrication technique that is used in lots of industries. Its wide use is helped by the fact that you can weld in various positions and create joints to satisfy different needs. But, you always need to ensure the welds are good quality. Our on site x-ray services and other forms of NDT are a good way of testing this.
To ensure we offer the best results with our NDT, we ensure our operatives have a wealth of knowledge and experience. For one thing they know about the various weld joints they may encounter and need to test. Below is a little bit of information about some of the most common ones.
This is the go to type of welding and one of the easiest to master. It requires the welder to place two pieces of material side by side so they run parallel and do not overlap. They then weld a joint along the line where they come together. Several different styles of welding can be used here, including square groove, bevel groove, and U groove.
In some cases you need to overlap the metals before you weld them. This is most commonly necessary when the pieces have differing thicknesses. The welds can be on either side, or both in some cases. The style of welding here can include slot, spot, and J groove.
When metals come together at a right angle you need this kind of welding. It is particularly popular for joining pieces of sheet metal to create products like boxes and box framework. The weld is usually on the outer edge. Styles of welding to achieve this can include edge, corner flange, butt, and more.
One of the trickiest welds is to join two pieces of sheet metal in a 90 degree T shape. The challenge is keeping the pieces in place and joining them effectively. Once again there are several styles of welding to use here, including fillet, plug, and melt through.
This type of joint is most common when the pieces of sheet metal have flanged edges. Here the edge is bent over to create a flange that will add strength. Welding pieces with these edges is similar to creating butt joints, so the pieces are often sided by side and the weld is on the same edge. As a result, you can use most of the same welding styles.
Choose on site x-ray services
Format NDT Ltd has the skills to test all kinds of welds. We can use x-ray or gamma radiography to see inside a weld to look for flaws such as pores and laps. This can help to determine if the weld will be strong and stable.
Our on-site x-ray services are useful to clients all over the UK in different industries. For example, we can support fabricators who want to test the weld quality on different products. In addition, we can offer testing for items in-situ, including pipes, boilers, water tanks, and more.
