Seam welding is a resistance welding process for joining metal sheets in continuous, often leak tight, seam joints by directly applying opposing forces with electrodes consisting of rotary wheels. The peripheral shapes of the electrode wheels concentrate the current and the heat generation. Seam welding is mostly applied in manufacturing of

The general heat generation formula for resistance welding is: Heat = I2 x R x t x K. Where "I" is the weld current through the workpieces, "R" is the electrical resistance (in ohms) of the workpieces, "t" is the weld time (in hertz, milliseconds or microseconds), and "K" is a thermal constant. The weld current (I) and duration

From a resistance welding point of view the part must be held or positioned in the proper orientation and alignment to meet the part specification. It must stay that way until the electrodes have closed on the part. Fixtures or tooling frequently perform this function. PIN LOCATING 4 PROJECTIONS.
This paper proposes a high-efficiency energy storage system within the micro resistance welding device based on battery-supercapacitor semi-active hybrid
Resistance welding machines invariably have at least one electrode which moves with considerable force; in this respect they closely resemble a power press. If a machine is operated while a finger or hand is between the electrodes or platens, severe crushing will result. The risk of crushing should be considered for each machine and a suitable

Issued by: State Administration for Market Regulation; Standardization Administration of the People''s Republic of. China.
Micro resistance welding is one of the most effective ways to obtain permanent joints of metal parts. The quality of welded joints strongly depends on the characteristics of the power supply of
Four definite segments or periods of timing are set up on a resistance spot welding machine during one welding cycle. Squeeze time. Weld time. Hold time. Off time. Squeeze time. It is the time between the initial application of the electrode pressure on the work and the initial application of current to make the weld.
For welding transformer''s types, the impact can be seen if comparing between AC & DC spot welding -AC takes more 10% in total energy to produce same weld size compared to DC [4] . Under welding
amplitude for micro resistance welding typically ranges from hundreds to thousands of amperes and depends on the material type and thicknesses of individual parts [1], [2].
Spot welding, a form of resistance welding, is a process used to join two or more metal sheets together by applying pressure and heat to the weld area. It involves the use of electrodes, typically made of copper, to apply an electric current to the metal pieces. This current generates heat due to the resistance in the materials, causing the
