Resistance Welding and Fusion Welding (9) Flashcards
1
Q
Resistance Spot Welding (RSN)
A
- Used with Lap Joints
- Cab be manual or automated (robotic welding of car bodies)
2
Q
Resistance Spot Welding (RSW)
A
Similar to Spot Welding, one of the parts has small projections which concentrate heat at desired locations.
3
Q
Resistance Seam Welding (RSEW)
A
Series of overlapping Spot Welds accomplished between the wheel electrodes.
4
Q
Flash Welding (FW)
A
Produced by a flashing action and pressure. Brought together slow and smashed together. (Butt Joint)
5
Q
Upset Welding (UW)
A
Pressure is applied before the current. No melting occurs.
6
Q
Fusion Welding
A
The edge of the workpieces are melted and fused together. A filler metal is added to form the weld. The weld area forms a mold/basin for the molten filler metal to fill.
