Introduction
Electromagnetic pulse welding is an innovative solid-state welding technology that belongs to the group
of pressure welding processes and is based on the use of electromagnetic forces to deform, accelerate
and weld workpieces. No external heat source is used, the connection is only created by a high-velocity
impact.
The increasing use of the electromagnetic pulse welding process has created the need for a standard, to
ensure that the welding operations are carried out in the most effective manner and that appropriate
controls are performed on all aspects of the implementation.
To be effective, welded products need to be free from problems in production and in service. To achieve
this goal, it is necessary to provide controls from the design phase through material selection, choice of
parameters, the fabrication itself, and inspection. For example, poor design can create serious and costly
difficulties in the workshop or in service. Incorrect process parameters and/or material selection can
result in welding defects. Welding procedures need to be correctly formulated and approved to avoid
weld discontinuities. To ensure the manufacture of a quality product, management need to understand
the causes of potential problems and implement appropriate inspection procedures and subsequent
quality measures. Supervision should be implemented to ensure that the specified quality is achieved.

The equipment shall be adequate for the concerned application. Welding equipment shall be capable of
producing welds that meet the acceptance levels specified in 4.8.4. Welding equipment shall be
maintained in good condition and shall be repaired or adjusted when a welding operator, inspector or
welding coordinator is concerned about the capability of the equipment to operate satisfactorily.
4.4.2 New equipment
After installation of new or refurbished equipment, appropriate tests of the equipment shall be
performed. Such tests shall verify that the equipment functions correctly.
4.4.3 Reproducibility and validation tests for qualified machine welding settings
