2. Electric resistance welding - Wikipedia

   en.wikipedia.org/wiki/Electric_resistance_welding

   Seam welding has been used to manufacture steel beverage cans but is no longer used for this as modern beverage cans are seamless aluminum. There are two modes for seam welding: Intermittent and continuous. In intermittent seam welding, the wheels advance to the desired position and stop to make each weld.

3. Laser beam welding - Wikipedia

   en.wikipedia.org/wiki/Laser_beam_welding

   In the traditional type, the laser output is moved to follow the seam. This is usually achieved with a robot. In many modern applications, remote laser beam welding is used. In this method, the laser beam is moved along the seam with the help of a laser scanner, so that the robotic arm does not need to follow the seam any more. The advantages ...

4. Orbital welding - Wikipedia

   en.wikipedia.org/wiki/Orbital_welding

   A successful orbital weld is 100% automatic and repeatable as long as the operator monitors variables and performs periodic inspections of the weld seam for complete penetration of the weld. Noticing that a variable has changed during the welding process is a necessary skill for orbital welding technicians and operators that can be easily missed.

6. Weld purging - Wikipedia

   en.wikipedia.org/wiki/Weld_purging

   Sheet metal joints might be made on a seam welding machine where weld purging is carried out automatically as part of the machine design. Where sheet metal is formed into tanks or vessels prior to welding, the inside of the vessel can be purged with a flow of inert gas, however for larger sizes the cost of the gas and the time taken is unrealistic.

7. Autogenous welding - Wikipedia

   en.wikipedia.org/wiki/Autogenous_welding

   Autogenous welding is a form of welding in which the filler material is either supplied by melting the base material or is of identical composition. [1] The weld may be formed entirely by melting parts of the base metal, and no additional filler rod is used. There is some variation in the use of this term.

8. Ultrasonic welding - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_welding

   Ultrasonic welding of thin metallic foils. The sonotrode is rotated along the weld seam.. Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld.

9. Cold metal transfer - Wikipedia

   en.wikipedia.org/wiki/Cold_Metal_Transfer

   Cold metal transfer (CMT) is a welding method that is usually performed by a welding robot. The CMT machine detects a short circuit which sends a signal that retracts the welding filler material, giving the weld time to cool before each drop is placed. This leaves a smooth weld that is stronger than that of a hotter weld.
