Why is fluoride slag used in positional welding?
The more fluid fluoride slag designed for positional welding is less easily removed. Basic fluxes - the high proportion of calcium carbonate (limestone) and calcium fluoride (fluospar) in the flux reduces the oxygen content of the weld pool and therefore its surface tension. The slag is more fluid than that produced with the rutile coating.See all results for this questionWhy are neutral fluxes used in arc welding?Neutral fluxes are designed to have little or no effect on the chemical analysis of the weld metal and therefore on the mechanical properties. They contain low silica, calcium silicate and alumina and do not add significant amounts of silicon and manganese to the weld.See all results for this questionWhat is Submerged Arc Flux? - Welding Ovens by KeenThe utilization of a strip electrode for surfacing may be done to save money. This particular welding system uses the strip electrode and flux to make a corrosion-resistant overlay on a less expensive base material such as stainless steel. During this procedure, a wide, uniform bead is produced that has minimum penetration.
What happens to the flux in a weld pool?
The flux may also suffer mechanical damage during recirculation, breaking down to form a dust. Although a small particle size is capable of carrying a higher current, too many fines in the flux will give rise to gas being trapped between the slag and the weld pool.See all results for this questionWeld-FAQ: Useful Answers to Common QuestionsWeld-FAQ.

The list of Titles of Frequently Asked Questions, is in this first page.Weld overlay - WALDUNWhen two or more metal-specific properties are applied to a base metal, we speak of welding coatings or overlay. The weld overlap can be achieved by the following methods: arc welding, plasma arc welding to shield the metal welding, self-shielding coring of the wire and arcs to shield the weld seam support and other industrial applications.

As with the wire, strip is available in a range of coil weights. Whilst the wire is relatively simple and is designed to match the parent metal composition and/or mechanical properties, the flux is far more complex. The functions of the flux are:
