INTRODUCTION PRELIMINAR STUDIES AND CONSIDERATIONS
MOUNTING AND CONSTRUCTION
There are some areas where the welding is not allowed. Do not weld on:
-

When welding, grinding or cutting near items such as brake lines, electrical cables,
etc., always take the necessary precautions for their protection, also considering
dismantling them, if necessary. Otherwise they could be damaged and not work
properly.
To get a proper weld, defects such as undercuts, fissure, blow holes, pits in the weld
seam, etc. should be avoided. If the welding bead is not good, it will result in stress
concentration that will have an effect on fatigue strength.
Examples of incorrect types of welded connections:
