What kind of weld should a lap joint have?
The joint design determines what type of weld the operator will need to produce to meet the acceptable quality standard. A few examples include T-joints, which require a fillet weld; butt joints requiring a groove weld; lap joints, which require fillet welds; and corner joints, which can be fillet or groove welds.
How does an electrode work in lap joint?
When the arc is of the intense heat produced, quickly melts the work piece metal under the arc and produces a molten metal. Simultaneously the end of the electrode melts and the molten metal is carried by the arc into the metal pool on the workpiece to provide a filler to the joint.

What are lap welds used for?
Lap Joint Welding They are formed when two pieces of metal are placed in an overlapping pattern on top of each other. They are most commonly used to joint two pieces with differing thicknesses together.
What is a lap joint metal?
A lap joint is the joint between two pieces of metal in which the edges or ends are overlapped and fastened together to produce a continuous or flush surface.
Should you weld both sides?
When you can weld from both sides of the joint, a full-penetration weld is easier to accomplish. For thin material, the edges can be butted together, a weld made on one side, and a weld made on the back side that fully penetrates into the first.
What are the 5 basic weld joints?
There are five basic welding joint types commonly used in the industry, according to the AWS:
- Butt joint.
- Tee joint.
- Corner joint.
- Lap joint.
- Edge joint.
What method in striking an arc is recommended for the beginners?
scratching method
The scratching method is easier for beginners and when using an AC machine. The electrode is moved across the plate inclined at an angle, as you would strike a match. As the electrode scratches the plate an arc is struck.

How do you fix a welding overlap?
Correcting Overlap in Welding Unlike other welding defects, it’s possible to fix a visible overlap by grinding the excess weld metal. Surface grinding smoothly at the base of the metal removes overlays.

How to prepare joints for welding?
You can also use edge preparation, air carbon arc cutting, and gouging to prepare the joint, depending on the type of alloy you are using. The application of cleanliness measures is critical during joint preparation.
What is a double lap joint used for?
This type of joint is used to join two overlapping members. A single lap joint where welding must be done from one side is shown in view A, figure 6-21. The double lap joint is welded on both sides and develops the full strength of the welded members (view B, fig. 6-21). An offset lap joint.
What is an offset lap joint used for?
An offset lap joint (view C, fig. 6-21) is used where two overlapping plates must be joined and welded in the same plane. This type of joint is stronger than the single lap type, but is more difficult to prepare.
What are the different types of welding joints?
There are five different types of welding joints as defined by the American Welding Society. They each boast unique characteristics in terms of how materials may fit together. Keep reading to learn more about each specific welding joint. Corner joint welding refers to instances in which two materials meet in the “corner” to form an L-shape.
