GB/T 8366-2021Resistance welding - Resistance welding equipment - Mechanical and electrical requirements (English PDF)

1 Scope

This document defines and specifies the specific electrical and mechanical properties of the following resistance welding equipment.

---Resistance spot welding;

---Projection welding;

--- Resistance seam welding;

---Butt welding 1); and

---Flash welding 2).

This document specifies the technical parameters of the equipment and the methods for measuring these properties.

Not all requirements apply to all types of equipment.

Resistance welding equipment includes the following types.

---Single-phase AC resistance welding machine;

---Single-phase secondary rectification resistance welding machine;

---Single-phase inverter resistance welding machine;

---Three-phase secondary rectification resistance welding machine;

---Three-phase primary pole rectification resistance welding machine (sometimes called inverter);

---Three-phase inverter resistance welding machine.

This document does not apply to solder mask transformers that are separate from the equipment.

Note. IEC 62135-1 specifies the safety requirements for resistance welding equipment.

1) Usually refers to the non-preferred term, buttwelding.

2) Usually refers to the non-preferred term, flashbuttwelding.
