Welding Techniques for Strong Joints

What is a weld applied to the other side of a joint before a groove weld is started called?

a) Fillet weld b) Plug weld c) Spot weld d) Seam weld

Answer:

A weld applied on the opposite side of a joint before initiating a groove weld is identified as a back weld.

In welding, the use of different techniques is crucial to ensure strong and reliable joints. One such technique is the back weld. This method involves applying a weld on the opposite side of a joint before starting a groove weld.

Back welding is commonly used to reinforce joints and prevent any weak or brittle areas in the final welded structure. By adding this extra layer of weld on the back side of the joint, it helps improve the overall strength and integrity of the weld.

While fillet welds, plug welds, spot welds, and seam welds are all important types of welds in various welding processes, the back weld specifically refers to the weld applied on the back side of a joint before a groove weld is initiated.

By incorporating back welding into your welding techniques, you can ensure that your joints are more durable and resistant to failure. It is an essential step in achieving high-quality welds that meet the required standards for strength and reliability.
