Do You Know The Common Simple Terms Of The Welding Process?

Welding, also known as welding, is a manufacturing process and technology that uses heat, high temperature, or pressure to join metals or other thermoplastic materials such as plastics.

The earliest modern welding technology appeared at the end of the 19th century, so the welding process can be regarded as a conventional process technology for structural forming, which is widely used in various industries. today. Let's take a look at the common and simple terms for welding!

What are the parameters that represent the fillet weld geometry?

According to the appearance of fillet welds, fillet welds can be divided into two types: convex fillet welds and concave fillet welds:

The fillet acts like the load-bearing foot of the weldment in the cross-section of the fillet weld, and the minimum distance from the toe of one weldment to the surface of the other is called the fillet. The fillet value determines the bonding strength of the two weldments and is the most important parameter. Convexity In the section of a convex fillet weld, the maximum distance between the line connecting the weld toes and the surface of the weld. Concavity In the cross-section of a concave fillet weld, the maximum distance between the line connecting the weld toes and the surface of the weld.

Weld width: In a single-run weld cross-section, the distance between two weld toes is called the weld width. Reinforcement height: refers to the height of the weld metal part above the welding toe line on the weld surface, called reinforcement. Reinforcement increases the cross-section of the weld, which increases the load-bearing capacity, but results in stress concentrations at the weld toe. In order to ensure the strength, it is usually required that the weld metal cannot be lower than the base metal, and its height will increase with the increase of the base metal thickness, but the maximum value should not exceed 3mm. Penetration On the cross-section of a welded joint, the depth to which the base metal melts is called penetration. A certain penetration value can ensure the bonding strength between the weld and the base metal. After fixing the filler metal material (electrode or wire), the size of the penetration determines the chemistry of the weld. Different welding methods require different penetration values. For example, in surfacing welding, in order to maintain the hardness of the surfacing layer and reduce the dilution effect of the base metal on the weld, a smaller penetration depth is required under the premise of ensuring the penetration depth.
