How to weld > Welding on primed steel
Suitable welding performances
Welding can be performed with or without leaving the primer in the joint.
When the primer is left on it is possible to attain advantageous results of the general properties in the joint. It is also feasible to perform welding with the same parameters as for welding a joint without a primer. However, the outcome may be further improved if the primer is removed from the joint and the adjacent surroundings prior to welding.
If the primer is left on in the joint, MAG-welding with basic types of flux cored wires is a good option since it supports a lowered level of porosity. However, beneficially low porosity levels in the weld metal can be attained in general for all other types of welding methods welded with the recommended consumables.
