Welding technologies have come a long way and now various kinds of welding techniques are available in the market that can be used to join metal parts together.
Trailer welding fabrication is a crucial aspect of manufacturing and maintaining the trailers. It is about fixing broken metal pieces and ensuring a strong, safe, and durable trailer carrying heavy loads on long journeys.
The biggest and heaviest loads of cargo on highways and roads are transported by trailers, and their steel chassis needs to be strong enough to support these loads at all times.
Welding joints are one of the most important aspects of making a trailer because it is a spot on the vehicle that is more susceptible to stress than the main steel beams on the chassis.
Let us understand the 5 basic types of welding joints that are widely used in trailer repairs.
5 Common Types Of Weld Joints
Here are the 5 common welding joints used in trailer repair services.
- Butt Joint
A butt joint is one of the most common types of joint that is used in the trailer repairs. The two workpieces are joined together by keeping them in the same plane, with their edges meeting and lying parallel.
Welders often use butt joints to fix broken chassis of trailers. It not only fixes the broken chassis by giving a smooth weld but also provides the necessary strength and support to carry a heavy load.
Butt joints provide good strength when fitted and welded properly with each other. They may also be welded with a backing bar or backing strip to further increase their strength.
- Corner Joint
This type of weld joint is used to repair and fix the corners of a trailer. In it, the metal pieces are joined at 90 degrees forming an L shape at the corners.
These weld joints are easy to assemble but also require a little edge preparation before the metal pieces are welded together. It is necessary to maintain the proper shape and symmetry of the corners.
In total, there are two types of corner joints, one is open and another is closed corner joints.
In an open corner joint, there is a little space at the corner from the outer side of the joint. On the other hand, in closed joints, the corners of the joints are fixed in a way that leaves no space from the outer side of the joint.
- Edge Joint
An edge joint is created when the edges of the workpieces are bent and placed parallel or nearly parallel to each other.
There are different types of edge joints depending on how the edges are prepared. You can leave them in a square shape or you can prepare them by cutting or grinding them into a J-groove, V-groove, or a U-groove.
After fixing the edges you can also weld them for additional rigidity. There are many similarities between corner joints and edge joints.
Typically, an edge joint is on the inside of the workpiece, but a corner joint is on the outside.
Material thickness and application requirements are major factors in the selection between an edge joint and a corner joint.
- Lap Joint
A lap joint is formed when the two workpieces overlap each other. The welding is done on the part where two pieces intersect.
A lap joint has good mechanical qualities, particularly when the overlapping components are welded on both sides. Welding both sides of the metal pieces gives the additional strength to the joint.
By measuring the thickness of the two workpieces you can determine the required overlap in the joint. A greater amount of overlap is required with thicker materials.
Lap joints are commonly used to join workpieces, such as adding metal flooring to the trailer or patching holes. While using lap joints make sure that there is no gap or space between workpieces, it is necessary to get a smooth and clear finish.
- T-Joint
A T joint is formed when the edges of two workpieces meet at 90 degrees and take the shape of a T alphabet.
In a T joint, the edge of one workpiece is welded against the flat surface of another. The strength of a T joint is maximized when it is welded from both sides.
This type of joint requires no preparation before welding. It can be easily implemented when the correct parameters and welding techniques are used.
T joints can be welded in flat, vertical, horizontal, or overhead positions, while other types of joints can be difficult to weld in various positions.
