what is the difference between ultrasonic welding & radiographic welding
back hand welding is when you pull the welding rod or whatever it is that you are using and forehand is when you push it ahead
"Automotive" means that such a person is specialized in cars.
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.
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc 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.
UT, with regard to welding, stands for Ultrasonic Testing.
industrial applications ultrasonic cleaning,ultrasonic cutting,ultrasonic machining,metal forming,metal welding, medical applications
What creates the heat is the flame inside the torch
The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.

In plastic welding, equipment used includes plastic welders (some are ultrasonic) and as with any type of welding, protective equipment such as gloves.
High frequency welding is a process where plastics such as PVC are heated with high frequency waves. This is to soften the plastics for easier molding.

Branson Ultrasonic offer welding technologies. For example, they offer Linear Vibration Welding, Orbital Vibration Welding, as well as many other types of welding tehcnologies.
"Automotive" means that such a person is specialized in cars.
in arc welding only heat is used to weld metal. but in resistance welding pressure will also be used along with heat.
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.
