Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
What is difference between seam welding and spot welding?
The only difference between the two is that projection welding requires preparation of the joint members in the way of adding a preformed dimple or projection. Spot welding is used without such preparation to the joint members. it's just heat and pressure.
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
Why spot welding robot not used in arc welding?
A spot welding robot has generally 5 axis opposed to an arc welding robot that needs 6 axis. The controls and communication channels with the welding power supplies are configured differently as well.
What is land in spot welding process?
