Basic Welding Joints

Welded joints are one of the most commonly seen joints although there is much more that goes into them than most realize. A Weld Joint is characterized by being the place where two or more metal pieces are joined together through the introduction of melted solder and high heat. There are 5 types of weld joints, corner, lap, tee, edge, and butt. Each one has it's own unique qualities and the best places to implement. 

The butt joint is formed by placing the ends of two parts together. The two parts either lie on the same plane or are side by side. It is the most simple type of weld joint. There are a few different types of welds involved with a good butt joint.

Next, let's focus a little on the corner joint. The corner joint is another pretty basic option for beginners and looks exactly how it sounds. This joint is identified by the two welded pieces being joined together in the shape of an L. It is important to remember to weld both the front and back of the L shape for structure and strength.

T-Joints are commonly used in construction because they offer a wide range of placement flexibility. These look exactly as they sound, a joint that forms two 90 degree angles and when welded resembles the T of the English language.

Welding along the edge of two parts to fuse them together is referred to as, you guessed it, the edge joint. Because this joint can not fully reach the complete thickness of other joints, it can not be used in a place that will have high stress or pressure.

A lap joint is commonly used to weld together two pieces of metal with differing thickness. They are laid across each other to overlap and are joined on each end of the metal. This type of weld is used in a variety of different scenarios, all depending on the situation.

When working on projects of welding steel, we recommend using galvanized tubing and piping from Ohio Galvanized Tube. Specializing in over 20 product applications, there is a type of steel tubing for every project. Visit our website here!
