Abstract

Metal parts or plates are heated to prepare them for arc welding by (a) sand or shot blasting to SA3 quality, (b) spray coating to a thickness of 10-100 u with a primer paint based on anti-rust metal powder of adequate granulometry dispersed in a specific binder and mixed with powders of Al and/or metallic oxides, graphite and/or usual pigments, and air drying. Used esp. in naval construction. The arc welding which may be automatic, semiautomatic or manual may be effected immediately or after a lapse of several months without intermediate treatment and without onset of corrosion.
