Upselling

[Tracie Lynn]

Upswelding is a technique used in welding where the workpiece and filler metal are both heated to a high temperature. This causes the filler metal particles to melt and bond with each other, resulting in a stronger weld. It is often used to strengthen weak spots in a joint or weld, making it an important tool in the welding process.
