5 Stud Welding Procedure
This chapter contains the basics of stud welding, how you must actually proceed, and
what must be observed. You learn to select correct welding parameters and which
welding elements can be used.
5.1 Safety Instructions
Improper operation of the power unit is LIFE-THREATENING!
Threat to life
– by electric shock and arc
– by toxic vapors and airborne particles
– by red-hot metal spatters (fire risk)
– by blow-up of explosive gases and materials
– during welding of hollow parts
– by strong magnetic fields to persons fitted with a pace maker
THREAT TO LIFE by electrical shock and arc
During the actual stud welding process, do not touch the welding
elements, chuck, or retaining nut nor any electrically conductive
parts in their vicinity. These are all electrically life.
Step onto an insulating mat, if you have to weld under the
following conditions:
– in confined rooms with electrically conductive walls
– under confined conditions between or on electrically conductive
parts
– with restricted freedom of movement on electrically conductive
parts
– in wet or hot areas
When operating the stud welding unit, you must not wear any
metallic jewellery incl. wrist watches, especially on hands. Remove
any electrically conductive or electro-magnetically sensitive parts
from your body before you start welding. In this way, you avoid the
risk of damage by electric shock or influence of electromagnetic
fields.
